My twin sons were seen at Drs Roberts and deMarsche for all their orthodontic care. The experience was always excellent, right from the initial consultation, to scheduling appointments, to the friendly on-time staff, and the big game room. Quite a different experience than I had at another orthodontist where I grew up! Highly recommend Drs Roberts and deMarsche.

Dr. Roberts and de Marsche have a great office! Dr. de Marsche always answers any questions I have and the staff is so friendly. I get to come in on Saturday mornings (which means I don’t have to take off work!!) and my teeth have been looking great ever since I started coming here!

Drs. Roberts and de Marsche are extremely experienced in their practice and its evident in their work. I was very excited about their Saturday hours in Lawrenceville. I have been able to make the commute from NYC easily as necessary. +1 for adult Invisalign!

“Excellent service, very courteous and professional staff. Drs. Roberts & DeMarsche have treated both our children and we are more than satisfied with their pretty smiles. Facility is very clean and entertaining for little children with ample of parking. There is no wait time and they are always accomodating with appointments. Entire staff is very committed to providing excellent care and dedicated to their profession. I would absolutely recommend my friends and family to get their orthodontist treatment here.”

I went to Lawrenceville Othodontics for Invisalign in 2014 because I heard good things about the professionalism of their staff and the quality of their work. Drs. Roberts & de Marsche exceeded my expectations as they saw me through my entire treatment plan and had my teeth *perfectly* straight in less than 1 year. Not only are they experts in their field, but they are personable, have a great staff, and their office is beautiful (and conveniently located) too! This duo represents the best NJ and PA has to offer in orthodontics, and I would highly recommend them for any child or adult looking for orthodontic care today!

I was a patient here for many years when I was a kid. My sister and brother came here as well. Everyone was so friendly and welcoming every time we walked in. As kids, we loved playing in the big game room and watching the movies on the big screen tv. I have come back a few times as an adult and everyone was just as kind. I was always in and out quickly when I had something fixed. Great orthodontists and very friendly!

I’ve had an excellent experience here. I came in on May 2010 with horrible teeth to be honest and had no idea what was going to happen. 2 years later today on May 30 my braces have been taken off and my teeth are straight. Dr. Roberts and the rest of the employees make you feel comfortable as soon as you walk in. Dr. Roberts himself is a great guy and very hilarious. I wouldn’t want to have had this experience done anywhere else. If you want to great doctors & staff to help you come to Dr.Roberts i promise you won’t regret it!

Drs. Roberts & De Marsche are wonderful orthodontists. I have been going to there office since I first had braces in middle school; for over 10 years. They are both extremely friendly and helpful and love what they do. The rest of the staff always greets you with a smile and remembers who you are. The atmosphere is very professional and personable; there has never been a visit where I haven’t felt comfortable and welcome. There office is great for kids too. They have a wonderful game room with fun arcade games and a big screen TV. As well as, a quiet study room for those students who need that extra time to get a head start on their studies. I am in my twenties but still revisit their office time to time for some quick check ups and adjustments. You are in good hands with Drs. Roberts & De Marsche and you’ll be happy with your new smile!

Dr.Roberts & de Marsche is a great facility to get orthodonitic work done , I love this place. Everyone is great and greets you with a smile and by name. They are incredibly on time and the atmosphere is so relaxing. I wish I could get all of my dental needs done there.Thanks Dr. Roberts and Staff

I’m so glad I went with Dr. Roberts! We’re finishing up my adult treatment and I am very happy with my smile. Dr. Roberts is skilled, personable, and truly cares about making sure his patients leave with nothing less than a stellar smile! As a patient, it can be really difficult choosing the right orthodontist for you when you don’t know anything about orthodontics (like me). I consulted with several doctors, read their online reviews, and looked at photos of their work, but in the end I still didn’t feel confident that I could choose the best treatment plan for me (was given vastly different treatments). I chose Dr. Roberts because I liked his work and because I felt very comfortable with him (and his staff) during my consultation. He explained my proposed plan to me and he and his staff didn’t mind answering my millions of questions when I called back later after doing more research. About a year after I started my treatment, I moved cross-country. This drastically slowed down my treatment because I couldn’t schedule regular appointments. Earlier this year when I went back out West after the holidays, I bit into something really hard and caused damage to my braces. It was an easy fix, but I couldn’t make it back for another six months. By the time I saw Dr. Roberts again, the problem was much worse than it would have been if I had just seen him soon after it happened. This added about half a year’s visits (with regular appointments) to my treatment. It was no problem at all and Dr. Roberts is taking care of it. I can’t imagine how much extra work he has had to put into my braces because of my insanely irregular visits. I’ll bet we could’ve ended my treatment sooner if he wanted (I’ve been seeing him for 3+ years), but Dr. Roberts won’t get these things off me until he’s sure I have my best smile. I don’t know if other doctors would have been as pleasantly accommodating as he’s been! (I’d even left some of my consultations feeling rushed and inconvenient.) His office is friendly, clean, and there’s always good music playing (and a movie for kids in the waiting area). Would recommend!

I just finished my invisaline treatment by Dr. Roberts. He did a fantastic job. Also, His staff was accommodating and very friendly. I would have no problem recommending Dr. Roberts to my friends and family. Thanks Again!

Everyone in the office is so nice and really helpful. I had started invisalign express with a dentist in my hometown and transfered to Dr. Roberts. By the end of the treatment my teeth looked good but Dr. Roberts thought that we could do better with a new set of invisalign which came at no charge to me. 8 years after I got my braces off my teeth look better than they ever have! Thank you Dr. Roberts and friends!

Couldn’t ask for a better orthodontist. I had braces and a child and needless to say I had to put them back on as an adult… Dr. Roberts made sure I didn’t have to wear them very long, which was great. They also were very flexible on payment methods and the staff was friendly and great! Definetly RECOMEND!

Google User

Excellent meticulous work. I am very happy with the result, as well as the excellent careful work throughout the more than 2 years I went to him. He is also a very nice guy!

Dr. Roberts did a great job with my teeth! I went through about a year of invisalign and appointments were always fast, informative, and the staff was very polite. Kathy also did a great job putting in a bonded retainer on my lower teeth. Great place to go and super convenient to Center City!

Dr. Roberts is an excellent orthodontist! My teeth were in really bad shape. I had a terrible bite and they were very crowded. Dr. Roberts gave me my smile and confidence back. I get so many compliments on how beautiful my teeth look. I couldn’t be happier! I would recommend him to anyone. The staff is also a plus to this practice. Everyone is very professional and friendly at the same time. Great Office!!!!!!

Dr. Roberts is amazing! What a sweetheart… I had my braces in for 1.5 years, was able to get them off before graduating. He made my visit pleasant, went out of his way to help without me ever having to ask. The location is super convenient as well. His staff all are friendly and there’s never a long wait.. 5 minute tops! I would highly recommend this office, and have to a few friends! I love smiling now! To show off his great work!! 🙂

These folks do great work. They care about getting everything just right (I am pretty particular about things). I am an adult male – had regular braces with clear ones in the upper front. Very few people noticed and all of the feedback was positive. The office is beautiful and very clean – enjoyed the whole experience.

Kelly Anne Dolan

I am extremely happy with the results that I have gotten as an adult patient with Dr. Roberts. I had a lot of crowding and misalignment, and he fixed all the problems wonderfully. My orthodontic treatment has also greatly improved my placement and articulation for singing. Dr. Roberts is a true expert and his course of treatment has given me a completely new smile. The staff is very professional, courteous, and knowledgable as well. I highly recommend Dr. Roberts for anyone looking for an orthodontist–the transfomation is amazing!

I’ve been coming here for a little over 3 months and have always had a really good experience. Everyone is always friendly and helpful. I just got my braces off today and couldn’t be happier. My teeth are perfect! -Nicole
