Testimonials
Ostler professionals are very personable and great staff hygienist and Dr. Constantine is very thorough. I would rate this practice a 10 star review.
I highly recommend this practice. Thank you Dr. Libby and staff for taking such good care of me during all of my visits.
Vernell, Sue, Nota and Drs. Libby and Constantine are the BEST
Perfect dental practice! Dr. Constantine is excellent: light touch, highly skilled and great chair-side manner. I have been a patient for several years and have had a range of issues that required his expertise. The dental hygienists are also very good and the staff is very competent and pleasant. Just praise, no complaints. Can’t improve on perfection!
Dr Constantine is very professional, compassionate and knowledgeable. Always there when I need him. So glad and grateful to have him helping me with my dental issues . His staff is amazing, helpful and supportive. I highly recommend him for any kind of dental care! Melba S.
From the first phone call to an office I had never been to before, until the follow up appointment, I was very impressed by Dr Constantine & his staff. I happen to be a retired dentist myself so I was very familiar with the procedures that are common to my dental predicament, an emergency visit for a fractured premolar. Dr. Constantine’s office gave me an emergency appointment for that afternoon. The treatment could have been a root canal, a crown or an extraction. Thank you so much for seeing me that day. An x-ray was taken, I was numbed (very well) the broken part of the tooth was removed & I was reappointed for the crown I need. The office was clean, spacious, accommodating, & friendly. I had an opportunity to ask any questions I might have & I was in & out of the office in 45 minutes. Well done! I would highly recommend this convenient central Towson dental office to anyone, I was certainly impressed.
I’ve been going to them for something like 20 years. Even after moving out of area, I still drive 45 min to see them. Nora is incredible, I love her so much, I’ll be devastated when she retires. I hope whenever that happens I’ll be able to keep seeing Susu, because I had a great experience with her as well. Dr. Constantine (fantastic name) and Dr. Libby are phenomenal, I have all the trust in them. Everyone there is pleasant and kind. It’s rare to go anywhere 40+ times and never have a bad experience, but that’s what I’ve found here. Simply amazing, thank you!!
The best in way of trustworthy and personable dentists, friendly and efficient staff, and timely service. Dr. Constatine was amazing with our children, pulling off the impossible—giving needles without them knowing. If there were more stars I would use them! After 16+ years using them for our whole family, not a glitch. Top notch!
We love this dentist office! Everyone is so nice. Our whole family of 4 goes here from young kids to my husband who need surgery and an implant. Dentists are great with kids!
The staff is professional, safety conscious, provide education tips to improve dental hygiene, and always ready for the patient on your arrival. I know that due to the efforts of my hygienist Nora and Dr. Chris Constantine my dental health, and in fact general health, is markedly improved. From the reception desk to the treatment rooms this is an A+ practice!

So relieved to have my team at Osler Dental Professionals, Nora, Dr. Chris Constantine, and reception staff, always ready to take care of my dental hygiene needs. Today was my cleaning with Nora and exam from Dr. Constantine – tremendous plus to know that continued adherence to the plan of care has resulted in a good report. No caries, no discernible gum disease, no further bone loss! Thank you Osler Dental Professionals for all you do!
Osler Dental Professionals is an amazing place! The staff goes above & beyond to make you feel comfortable and to ensure that all of your dental needs are met. Dr. Constantine has a caring nature, which makes you feel like you’re a priority during every visit. You will not regret going to Osler Dental Professionals!
I’ve been going to the to Osler for about 3 years now. From the front desk to the back staff and Dr Constantine every one is amazing.Every one has excellent customer service skills. They do amazing work . I give the 10/5 stars. I would recommend to everyone and you won’t be disappointed
The staff is so pleasant and patient friendly. Even though going to the dentist is not my favorite activity, this practice makes it go as stress free as possible!!
I would recommend to a friend!
My experience at Osler Dental Professionals was nothing short of amazing. I had pretty bad anxiety towards the dentist from past experiences. My visit from start to finish was great. The front desk, the hygienist, and the dentist made me feel so calm and explained everything in great detail. Julie, the lead dental assistant was awesome! I would strongly recommend anyone looking for a dentist or a change from your current one.
What a great experience! Susu and Dr. Constantine are absolutely amazing: gentle, caring, easy to talk to! I highly recommend this dental proactive!
I have been going to Dr. Constantine and Dr. Libby for dental care for many years. The service I have received from the dentists and the dental hygienists is both kind and professional. The office staff is courteous and professional. I give them my highest recommendation.
I thought I might need significant work, but Dr. Libby fixed my problem by simply smoothing the edges where my tooth had chipped. He continues to earn my trust. I was running very late, but the efficient office managers assured me they could make it work, and they did. Thank you!
Outstanding practice.
Have been with Dr. Constantine for a number of years. He’s highly skilled, ethical & very compassionate. My best dentist ever and can’t recommend more highly!
This is our entire families dentist for many generations, they are THAT good. Look nowhere else, this is the only dentist in maryland that we trust or would even consider.
Dr. Constantine was very professional and kind. He continuously asked me how I was doing. I got a new crown and after several visits my permanent crown was installed today. I appreciate his gentle, conscientious manner. I would recommend him highly.
Love this dental practice! Many years ago Dr. Ed Gutman helped me overcome my fear of the dentist and I have been a patient of Osler Dental for almost 30 years! My dental hygienist, Nora, is wonderful!
Great professionals the Dentist was patient and didn’t make me rushed with all my many questions they earned my business today
I found Osler Dental using a Google search. Completed 1 implant in Nov. 2023… Dr. Constantine was very professional, very ‘clear’ in describing the process and everything worked out well! They also had the lowest price – compared to others…
I did return to see him because I, recently, had a bit of jaw pain – but even thought it has nothing to do with the implant – he gave me sensible suggestions on how to alleviate the pain I’m experiencing. Quality establishment!!
Highly recommend! I have LOTS of anxiety about going to the dentist. After my first visit almost 10 years ago! Dr. CONSTANTINE, Dr. LEWIS, NORA VERNEAL, AND JULIE are amazing and have been taking care of us very well. They always make me feel comfortable, welcome. I feel that me and my family are in a great hands. Thank you so much for all you do for us. Thanks tu SUSU for taking care of me today!!
The dental office is a beautiful space. The staff is friendly. My wait time was less than five minutes. And the best part of all is Dr. Constantine, who is friendly, competent, honest, and someone I feel really good about entrusting my dental health to. And this is how honest he is: another dentist told me I needed to get a tooth re-capped. I went to Dr. Constantine to do the job and he told me it could be fixed with a filling instead of capping the whole tooth.
Going to Oslar dental has been the most comforting experience I’ve had at a dentists office. The hygienist , Dr Constantine , and the office staff thoroughly expain everything and patiently answer your questions. This dentist is top notch and I recommend them highly.
I can’t express how much I appreciate them. From the front desk, I love Verneal,who is always so helpful and walks you through everything and answers any questions you could have. To Dr Constantine who is simply amazing. I am a very anxious dentist person. He is so caring, and makes sure that I know what he is doing, so no surprises. He understands my fears and concerns and makes sure that I am ok with every step. 100% recommend to everyone.
If you are looking for empathy ,compassion, kindness and professional treatment , this is the dental practice for
YOU! The moment you walk in to the time you walk out you are treated with a personal kindness I have NEVER experienced. I can only describe Dr. Constantine as SUPERIOR EXCELLENCE ⭐️⭐️⭐️⭐️⭐️ his attention to detail surpasses any dentist I have ever been treated by (trust me it’s been a lot). The communication and follow up you receive by him personally and his staff is beyond measure. I have been his patient for over 2 years , it’s been a journey and a life experience that has changed my life. It is of my opinion and experience ALL of the past dental practices I have had are only concerned with your money and getting you in and out as fast as possible. Dr. Constantine cuts NO CORNERS and while I was impatient at times he has the ability to make you see the logic of his treatment with superior LONG TERM results. If you are like me and have a fear of the DENTIST due to bad or traumatic experience(s) “FEAR NO MORE”. I use to say I hate the dentist however, I now say with the utmost honesty I LOVE MY DENTIST 🪥 🦷. I can guarantee you if you’ve read this review Dr. Constantine is the dentist for you! Don’t hesitate or look for another, he is and will be your saving grace. Thank you to everyone at Osler you are all the “crème of the crop”.
Dr.Constantine is definitely the best dentist I have ever had. He is an artist in his field. I am truly blessed to have him as my dentist. I also want to acknowledge his assistants and front desk for their remarkable service and kindness . They made each visit enjoyable.
One of my teeth cracked and the piece fell off. The office brought me in the very next day for an evaluation. I am always so grateful for this office’s caring kindness. And as expected, Dr. Constantine is going to be able to save my tooth!
Very professional staff and my appointments are on-time. Excellent dentists!
Osler Dental is top-tier in every element from staff to the only dentist I’ve ever enjoyed visiting. That’s not just for the amazing teeth work he did. Dr. Constantine is a straight shooter his ” genuineness and personable demeanor” is why I chose Osler after checking other providers. If you’re looking for a great dentist, especially for implants, Chris Constatine is the man.
Excellent service, they were able to see me super quickly and were incredibly knowledgeable, professional and friendly- highly recommend!
Dr “just call me Chris “ Constantine is an amazing dentist and is on the leading edge technologically. My tooth situation has never been great but it also has never been as good as it is now – he and his excellent team get the credit. Bridges and implants he created along with regular care by the technical staff have put me in a healthy state
I wish every professional medical office, regardless of specialty, was run as professionally and as “family comfortable” as Osler Dental Professionals. I trust their advice because I think they only advise a course of treatment they themselves would take.
If you’re looking for a dental practice where you can be treated courteously and professionally, and where you can truly relax in “the chair” then this is the place you should go. Life is good … and so is my smile!
Amazing people! I really let myself go and through several appointments, they have been extremely patient and kind, set clear expectations, and armed me with tools and education to take care of myself moving forward. Cannot thank them enough for how much they care!
I’ve been a patient since I was a child and highly recommend both Dr. Libby and Dr. Constantine. They truly care – not only for your teeth, but for your well-being. Once, Dr. Libby kindly rearranged his schedule last-minute so I could have an earlier dental appointment and be able to attend a friend’s funeral. The front office staff are friendly and accommodating. As a long-time patient, everyone knows my name (and how to pronounce it correctly!) and they care about how I’m doing.
Dr. Constantine is extremely gentle, which is wonderful for patients who may be nervous about going to the dentist. They always take the time to explain any treatments or procedures you may need and answer your questions. I always feel respected and cared for.
This is an excellent practice. I wouldn’t go anywhere else. ⭐️⭐️⭐️⭐️⭐️
In the many years that i have been a patient I have never experienced one moment of pain. The greatest compliment a dental patient can give!! They are truly amazing. Love you Nora😎
Dr Constantine is the best! I had a problem and he got me in the next day!
The exceptional care and professionalism of this dental office has been a true blessing. I also appreciate how clean it is… before, during and after the pandemic. I’m glad to have them on my dental health team!
The staff was very nice and considerate and I think the price is pretty reasonable for what I’m getting
I’ve been going to Osler for seven years. I came to them not knowing who they were. I had a consult with Dr Constantine and was very comfortable. I’ve had some rather extensive work done and I wouldn’t go anywhere else. Every person in that office is professional and also empathetic.
Been coming here 35 + yrs.
Most professional
Hygienist and dentist, fortunate to have found this dentist
Dr. Constantine is a very caring, gentle, and thorough dentist. While I’ve only been his patient for about six months, he has seen me through a couple of problems (including a cracked tooth) and I’m happy to have found him when we moved back to Baltimore. His staff is also excellent. I highly recommend Dr Constantine without reservations.
The entire medical team and front office staff provides excellent dental care and service. Grateful to be with Osler Dental for a long time. Highly recommended
The best Dental office ever and everyone is very professional & pleasant!
Friendly and professional staff make visits to the dentist enjoyable. Even for the dentist! Great location and beautiful offices at the Osler Medical Center (right across from UMD Saint Joseph’s Hospital).
I just had three dental implants completed today by Dr. Constantine and the whole process was easy and painless. I appreciate the attention to detail, expertise, and service that I experienced. I always compile a list of options and get estimates before embarking on any major project or service. Price is not the only factor I consider but the quality of service and value as well. I found the cost for my implants to be extremely reasonable compared to 2 other estimates I had received and I liked that the cost was inclusive of everything from start to finish and did not deviate. There were no extras or hidden fees- the whole process was very upfront. Dr. Constantine is probably the most diligent and detail oriented dentist I have encountered. It is evident he takes pride in his work. The staff are wonderful. Sue at the front desk does collect payment- in response to the previous review- because that is her job to do so. This is a business with considerable operating expenses and fully staffed. Collecting payment in advance is customary and absolutely necessary. The implant parts and crowns have to be ordered and they have to cover those costs in advance of treatment. I did have to reschedule and miss a few appointments during the course of my treatment and I found Sue and the staff to be very understanding. This is a practice that I would, and have, recommended to neighbors and friends without reservation.
I transferred my dental care to this practice about a year ago based on a family member’s referral and I’m very glad I did! They are both modern and classic in their delivery of professional dentistry. All the latest technology and advanced training one likes to see delivered in the manner of a family dentist of old. I have since referred others and highly recommend both doctors and their team! (They are also following strict safety protocols during the pandemic which made me very comfortable going in for a routine cleaning recently.)












I highly recommend Dr. Chris Constantine and Dr. Lewis Libby. My daughter, chipped her front tooth on a Saturday night. We reached out to Chris. on a Sunday morning, to see what we could do. Not only did he come to our house and help, but had us come into his office and he gave our daughter first hand treatment. He is an excellent dentist and overly cares about his patients. I highly recommend him and Dr. Libby to anyone that is looking for a great dentist.
A colleague referred me to Dr. Libby about 10 years ago. I’m forever grateful! My mouth was a mess. Not so today. Everyone is so professional and caring here. I won’t go to anyone else but Nora for cleanings. I had a dental implant completed by Dr. Constantine last year and it was the best decision. I just can’t say enough great things about the entire staff. Thanks to you all!
Dr. Libby is a truly great Dentist and a great human being also. His high level of expertise, thoroughness, caring and gentle attitude, and very fair pricing makes him an EXCEPTIONALLY good choice if you are looking for a dental care provider.

My extended family has been seeing Dr. Libby for decades and i do mean decades! they would not go anywhere else. My husband started seeing as a child years ago. He travels by plane, from Montana, just to see Dr Libby. He is the most sensitive, kind, caring, devoted dentist in Baltimore, and i felt absolutely no pain whatsoever, during or after during my procedure. He gives every patient a phone call at night from his home to check on them, after he works on them. He even sent me a follow up card in the mail, to let me know he is there; should i need him. Staff also goes above and beyond to help. He is the most professional, first class, 5 star doctor on the planet
I have always been anxious about going to the dentist but that changed when I started seeing Dr. Chris Constantine. He immediately put me at ease. He is thorough yet gentle. I would highly recommend him.
I would highly recommend both Dr. Libby and Dr. Constantine. I have had nothing but great experiences with both of them! They are extremely knowledgeable and always make me feel at ease… I still come to see them for my all of my dental work, even though I live in New York. I can honestly say I look forward to all of my appointments.
Can’t say enough good things about everyone in Dr Libby’s and Dr Constantine’s dental practice. Love them!!!
When I most recently came back to Dr. Libby after a period of geographical absence my gums and teeth were a mess! Today I smile gladly with a full tooth smile. The work Dr. Libby, Dr. Constantine, Nora, Angela, Julie, and Sue do is way beyond what I have experienced at other dental offices.
When I completed the health history form for their file the answer to “referring dentist” was “Dr. Libby’s father”. Dr. Libby the elder was my family’s childhood dentist from the start and when he passed away his son left the US Navy to take over what was a successful family practice.
Dr. Libby the younger is the original founding dentist of Osler Dental Professionals along with Dr. Chris Constantine (or “just Chris” as he like to say) along with a host of wonderful folks in various capacities.
I wish every professional medical office, regardless of specialty, was run as professionally and as “family comfortable” as Osler Dental Professionals. I believe their advice because I think they only advise a course of treatment they themselves would take.
If you’re looking for a dental practice where you can be treated courteously and professionally, and where you can truly relax in “the chair” then this is the place you should go. And by the way, I said I started with the elder Dr. Libby when I was a child – I have been retired from my work life for more the 18 years now. Life is good … and so is my smile!
Caring and talented doctors. Amazing staff. I can’t say enough good things about Osler Dental! Highly recommend!
Our whole family has been going to this practice for over 30 years. My children and now grandchildren all go regularly for cleaning and to care for whatever crops up. They are conservative in providing care options (i.e. don’t just try to sell you something). They are great in caring for my mother who has dementia and for grandkids to build comfort from their first tooth. My children and their children have no cavities and great smiles. My husband and I have healthy teeth and gums for a lifetime. They are up to date with the latest techniques and are fantastic with care. I can call anytime and they follow up after every procedure. I cannot say enough about the friendly, patient, helpful practice. This is the practice for your lifetime of dental care.
Dr. Libby is the most amazing dentist I’ve ever met! So happy to have found someone to fix my teeth, make me comfortable and teach me new things!
I absolutely love this practice! I actually started with Dr. Libby ‘s father many years ago. What a professional and caring group of people- from Drs. Libby and Constantine to Sue at the front desk. I actually relax when I see them because they are gentle with their work, unlike the dentist I grew up with. My oral health is in excellent shape due to this practice.??
Dr. Libby is great! I feel at ease when I come for a office visit, and he is generally concerned with my total health wellbeing and not just my dental posture.
Had wonderful experience coming in last minute with broken molar. Dr. Constantine saved me from dreaded root canal. He’s a very gentle and caring dentist.
Professional and friendly staff. Have had excellent care for my entire family.
