Check out what some of our happy patients are saying about us:

Dr. Roberts did my braces over 10 years ago, and I honestly loved him! I’m terrified of the dentist in general but I always remember him being very patient and understanding of my anxiety surrounding having my teeth worked on. Now that I’m older I’m having some issues with my teeth again (nothing caused by the braces, they’re still beautifully straight, just super poor quality and constantly breaking because of genetics– thanks dad) and I’m seriously considering going back to Dr. Roberts if the work I need done is within his realm of expertise. Over all loved the practice, great bedside manner and SUPER thorough!

Mitchell the front desk receptionist was very friendly and polite. Bill the doctor was also very friendly, funny and he answered all my questions. He made me feel very comfortable and confident. He gave me plenty of advice and information. Overall the whole experience there was great! I’m recommending this place to all my friends and family.

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!

Dr. Roberts is absolutely wonderful!  He did a beautiful job correcting my cross-bite, space between the two upper front teeth and between the canine teeth on the bottom.  I now have the beautiful smile I always wanted.  They provided me with a workable payment plan and his staff made you feel like family.  Although I’m happy to be done with wearing braces, I will truly miss my monthly visits to his office.   It was such a pleasant and relaxing experience.  Thank you Dr. Roberts and Staff.

Amazing orthodontist! He’s an expert! I saw him for my adult Invisalign. I wanted someone who knew they’re stuff. He’s definitely the guy. He was referred to me by my dentist. I really am a perfectionist when it comes to my teeth, and he definitely exceeded my expectations. The staff is also awesome and really helpful when it came to working with my insurance.

Michael C. from Puyallup, WA (Source: Yelp)


My daughter is a university of Pennsylvania student who needed braces. D r Roberts is a down to earth doctor that helped her make appointments around her college schedule. Her smile looks great and she was able to do the clear braces (invisalign) so she could actually take her braces off for graduation and other social functions. Dr. Roberts is very professional and understanding and this office was a great fit for our daughter while in college.

Sakinah W. from Philadelphia, PA (Source: Yelp)


I would like to give a special review for Dr. Roberts and his entire staff. Every time I come for an appointment, I am treated with dignity and respect. There is never a wait. There is always room for an emergency appointment. When you are in the care of Dr. Roberts he makes you feel just like you are family. I cannot thank Dr. Roberts enough for the miracle that he created with my mouth. No one would have ever believed it could have been done. Major construction was done and now I have a beautiful smile! All the other orthodontist prior to my initial consultation with Dr. Roberts, they wanted to break my jaws. I said oh no!! But Dr. Roberts said that he could work his magic and now look at me. I have recommended friends/colleague’s to him. Whenever I hear people speaking about their nightmares with other orthodontist, I say you should go to Dr. Roberts. I am forever grateful to this man!

Dr. Roberts is a fantastic orthodontist; personable and professional. The staff is also helpful and friendly, with the office providing space for families to play games and watch movies between siblings’ appointments. I had a wire pop out from my permanent retainer, installed by a different orthodontist, which was very uncomfortable, and the office saw me right away — the day before Thanksgiving.

I cannot say enough good things about my family’s experience with Dr. Roberts at Roberts & de Marsche. My two children and I were patients at his practice. I had Invisalign as an adult and my children had traditional braces. He was always warm and professional and I had confidence in all of his recommendations. All of our teeth were fixed beautifully. We get compliments regularly on how good they look. His office is clean and inviting. There is plenty of seating, a game room and another room to complete homework or other work. The staff is fantastic and very helpful and I never had an issue with scheduling an appointment. I would highly recommend Dr. Roberts.

Pengbo G. from Elkins Park, PA (Source: Yelp)


After two and half years of treatment, Dr. Roberts fixed my crooked teeth with his dexterous hands and broad knowledge. As a matter of fact, I was little indignant over those biased comment. Dr. Roberts’ expertise on adult orthodontic treatment is a real tour de force. Besides, Dr. Roberts himself is a real gentleman, suave, humorous and amiable. He has really good music taste by the way. Friendly staff, very short to none waiting time, convenient location in center city, clean facility, spacious penthouse (they are on the top of 15 storey building) with nice decor — I recommend anyone who wants to have a beautiful smile and great treatment experience.

Melinda P. from Philadelphia, PA (Source: Yelp)


Dr. Roberts did an amazing job transforming my teeth. I underwent the Invisalign procedure and was amazed at the results! Not only did Dr. Roberts straighten my teeth, but he went above and beyond with additional corrective measures. I have a brand-new smile! I highly recommend Dr. Roberts to anyone looking for an excellent orthodontist.

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!

Kara M. from Cleveland, OH (Source: Yelp)


Dr. Roberts did my braces 7 years ago (as an adult). I had severe crowding issues. He got my teeth straight in less than 10 months! My smile is still beautiful seven years later. Worth every penny I paid! At 23, my smile was the most expensive thing I owned. Totally worth it though. I wish I still lived in Philly so that I could send my daughter when in a few years.

Mesha B. from Denver, CO (Source: Yelp)


I am quite surprised to see negative reviews of this practice. Dr. Roberts and his staff are excellent. I went to him after being completely dissatisfied with another orthodontist in the area. At the time of my consultation, I had other braces in place. They were very accommodating to this fact and tried not to remove too many of the brackets already in place to minimize the cost to me. I was in residency while going through this process and the practice was nothing short of amazing in accommodating my ridiculous schedule. My teeth came out beautifully, my braces were off in time for my wedding and my photos came out great. Dr. Roberts also referred me to other great dentist when appropriate. He is hilarious and great to have as a dentist. As a physician, I know what it means to have a busy practice and also be pretty much on time for patients. I would and have certainly recommended him to friends. Excellent service.

Mary T. from Philadelphia, PA (Source: Yelp)


I highly recommend Dr. Roberts to anyone who is considering orthodontic treatment!  It took me awhile to commit to this regimen :), but I am so glad I did.  It is one of the best investments I’ve ever made.  I am on the last leg of my Invisalign treatments and my teeth have never looked so good. Dr. Roberts really knows his craft – I have absolute confidence in him — he is also very nice and extremely funny.  Plus my office visits have been very relaxing and even uplifting.  Everyone has been so nice and helpful.  They seek to make you comfortable and take seriously any concerns you have.  I will be sad to say goodbye when all is done!  Knowledge base, professionalism and customer service would all be an A+.  My dentist recommended only one orthodontist to me, and that person was Dr. Roberts.  I recommend him too!

Dr. Roberts has been my orthodontist since I was in Middle School, and I’ve consistently been impressed by the professionalism and geniality shown not only by Dr’s Roberts and Demarsche, but by their staff as well. Credit where credit is due- Dr. Roberts repeatedly exceeded my expectations. He would always explain what the next step in the process would be, and even explained why and how it would be the best approach. When I finally did have the braces taken off, and when I had a permanent lingual retainer applied, he even included (as a personal favor- free of charge) a little bit of bonding material to smooth out some natural irregularities in my teeth. I was very impressed by this, as it showed that he was willing to go the extra mile. Overall, though I suspect I won’t need orthodontic braces again, if I ever did… I would trust Dr. Roberts and Dr. Demarsche to get the job done.

All of the employees at this establishment worked their hardest every time I went in for an appointment and the result was amazing. Instructions were clear, appointments were easy to make, and everyone was always in a good mood. I would recommend this place to anyone who is looking to get braces.

Tammi A. from Cherry Hill, NJ (Source: Yelp)


My family has been going to Dr Roberts since my daughter was around 7 yrs old. My daughter has a medical condition that affects her adult teeth also causing her to lose teeth. She is now 15 yrs old. The work Dr Roberts has done so far on her, makes her beautiful face smile again! He and his staff are wonderful professionals. His receptionist  Lisa is friendly, knowledgeable, professional and she does an excellent job to accommodate your schedule for appointments.  It is a very inviting atmosphere in his office, with a little arcade room, good music and the location is great. I recommend anyone needing braces, to go see Dr. Roberts.

Nicole H. from Philadelphia, PA (Source: Yelp)


I was referred to Dr. Roberts by my dentist and I am extremely pleased with the results from wearing traditional braces for approximately 13 months. Both Dr. Roberts and his staff are friendly and patient. All appointments were amenable to my work schedule and Dr. Roberts is very nice, smiles a lot, and tells jokes while singing to the office music. I was apprehensive about getting braces as an adult, so I’m glad my experience was so positive in this office.

Jewel J. from Philadelphia, PA (Source: Yelp)


I had braces installed June of last year. They were removed July of this year. I am beyond satisfied with the results. Dr. Roberts and staff gave me the results I’d always dreamed of. He listened to what I wanted and took care in the alteration of my smile. Everyone at the office is kind and professional. The waiting room is well kempt and comfortable. I always recommend Dr. Roberts to my friends who ask.

Sharell Wilson (Source: Google)


My teeth were crooked and I had a lot of spaces. With patience and all the hard work of Dr. Roberts and his team I can know say I am happy with my smile. The staff were friendly and my journey took several years so we all grew to know each other on a first name basis. Once given the green light the practice opened back up after covid-19 and worked diligently to get me to the finish line as it relates to my transitioning from braces to retainers. As an adult getting braces I was apprehensive, but I would not change this experience for the world !! My teeth are straight and I know longer an concerned about my dental issues worsening with age. Thank you Roberts & de Marsche!!!!!

Monica W. from Philadelphia, PA (Source: Yelp)


Dr.Roberts made my adult orthodontic experience a breeze, I went in not knowing what to expect (adult braces consult) and he explained everything to me and made me comfortable throughout the whole process. Dr.Roberts and his staff are very experienced and their professionalism is outstanding. They really make you feel like family. I highly recommend this facility.

S H. from Philadelphia, PA (Source: Yelp)


Dr. Roberts has been my orthodontist since I was in the 6th or 7th grade. He told me what was wrong with my teeth and how they needed to be treated. He told me I needed braces and it did wonders on my teeth. Dr. Roberts is hands down the best person anyone can go to, if you need surgery on your mouth he will refer you to the best person he knows and they will get the job done no matter what and he will not let you down. He is the greatest man and specialist you will ever meet.

Neena P. from Dallas, TX (Source: Yelp)


When I was looking for an orthodontist who specializes in Invisalign a colleague of mine referred me to Dr. Roberts — and I couldn’t be happier! He is very thorough and takes his time to explain the process to you. As a professional in healthcare myself I am very careful with the healthcare providers I use. His office and equipment are clean, and his staff are courteous and helpful. I’m only halfway through the process but I (along with my family and friends) have noticed such an improvement in the alignment of my teeth. If you’re looking for an expert in orthodontics look no further!

Mandy G. from Norwood, PA (Source: Yelp)


I’m surprised to see two sub-par reviews here. Dr. Roberts did extensive orthodontic work for me while I was in college, and when all was said and done, my teeth were perfect. He put a permanent retainer on my top and lower front teeth, and they haven’t budged at all. I had a dentist appointment yesterday, in fact, and the doctor said, “I’d be willing to bet you’ll never lose a tooth in your life.” Without Dr. Roberts expertise, I definitely wouldn’t be in the position I am today. Not to mention that he’s hilarious and the adjustment appointments were nothing short of enjoyable. I’ve recommended him to anyone and everyone I know who needed orthodontic work – I went from hating my teeth to them being my best asset!

I am very excited to start treatment with Dr. Roberts. He has a great personality!!! He explained my options, was very through and super nice. His office in Lawrence Township is amazing and his staff is nice, caring and knowledgeable. Seeking orthodontic treatment as an adult, I was a bit uncomfortable and nervous, but they made feel excited about having one!

I have known both Dr. Roberts and de Marsche for about 30 years. I was the first paitent of my family, not a simple case for an adult, but it was a superb experience for me. My teeth are straight and repaired for life. Then over the years, our three children were very forturnate to be treated by Dr. Roberts and de Marsche with excellent results. They are their staff are true professional, always do the right thing by their patients and the entire experience is just aweseme. I highly recommend !!!

Audrey P. from Philadelphia, PA (Source: Yelp)


No one wants to get complicated orthodontic procedures, but if you need to this practice is wonderful. We’ve only ever seen Dr. Roberts, and he’s great. He explains what is needed and gives frequent updates on procedures. When brackets come free they always manage to get us in and see us quickly. After a consultation you will be given a price and a monthly payment plan. The staff is wonderful — very helpful and friendly. The waiting room is clean and spacious, with Disney/Pixar movies running and even a few free arcade games in a little separate room. The location is central Center City, convenient to many bus routes and close to many stores and restaurants, including the Apple store around the corner. Our only complaint is that sometimes when it’s busy there can be an overlong wait in the chair, but his happens only about 15% of the time.

Jonathan R. from Philadelphia, PA (Source: Yelp)


Five out of Five every time for Dr. Roberts and staff. I had my reservations to get braces as an adult, but boy, it was worth it! All thanks to Dr. Roberts and his staff! From the very first consultation to the last visit when my braces were removed this office was friendly, professional and most importantly experienced!. Dr. Roberts his technicians and office manager coordinated seamlessly with my dentist for information, provided flexible payment / finance options and scheduled office visits around times that worked for me. Keep in mind, my teeth were bad before braces! My before and after treatment pictures could land Dr. Roberts a cover story in all the major orthodontic journals. This office did a stellar job and I couldn’t be happier! Thanks!

Poker B. from Philadelphia, PA (Source: Yelp)


I’m so surprised to see any negative reviews of Dr. Roberts. Over the course of my treatment, Dr. Roberts made sure my teeth were perfect. It’s clear he has a ton of experience with Invisalign as well as traditional braces. This is the most important quality of an orthodontist- experience. Dr. Roberts is a pro. His assistants leave something to be desired, but Dr. Roberts himself performed the majority of my work.

PM S. from Philadelphia, PA (Source: Yelp)


I am also surprised to see low reviews here, because my experiences with Dr. Roberts, the male orthodonist, have been a complete joy. I have found him to be straightforward, kind, and competent, with a good sense of humor to boot. He’s meticulous and careful in his work, and the results have been very good as a result. Moreover, the front office has been very nice in all of my dealings, especially Lisa, the coordinator. I strongly recommend this doctor to anyone, but in particular to adults looking for orthodontial work.

Anna L. from Lawrence Township, NJ (Source: Yelp)


I first met Dr. Roberts about 20 years ago. My oldest child needed braces, we went to see him at the recommendation of my dentist. not only he took care of her, but he also took care of my other two children .I have always been uncomfortable with my smile, I thought it was time to take care of myself. during one of my routine dental cleaning I was talking to my dentist about it, and discussed different option he then once again  referred me to Dr, Roberts. At the advise of Dr. Robert I decided that Invisalign was the best way to go. Here I am not one year after with a smile that I had dreamed all my life. THANK YOU Dr. Roberts. I couldn’t be happier.

Megan T. from Titusville, NJ (Source: Yelp)


I came to Dr Roberts on a recommendation from a friend and I was not disappointed. Both my top and bottom teeth were severly crooked from my molars coming in and swallowing incorrectly (I pull on my teeth). They scraped the inside of my lips, made it difficult to eat, and uncomfortable to smile. In a few years, Dr Roberts had my teeth and jaw line corrected. He was patient with me through my set backs when I would forget to wear my trays. He was kind, reassuring, and knowledgeable. I would highly recommend both himself and his staff for invisalign.

Colleen O. from Camden, NJ (Source: Yelp)


I came to Dr. Roberts at the recommendation of a colleague at work who needed braces as an adult. I had braces when I was younger but my teeth shifted into my adult years and I decided that I wanted to invest in my teeth. I went in for my consultation convinced that I would only be willing to use Invisalign. After meeting with Dr. deMarche and Dr. Roberts, it was clear that I would get the best result from traditional braces. Honestly, I wasn’t excited about the idea of getting braces again but Dr. Roberts assured me that it would be worth it! A little less than two years later and I am getting fitted for my permanent retainers! I am so happy with the result thus far and I can honestly say that the time flew by. The staff is so friendly and professional and they really made every visit enjoyable. Thank you to the team at this office for making this whole experience pleasant!
