To say I had a difficult case with my teeth would be an understatement! I had countless surgeries and procedures (exposures of impacted canines, full top and bottom crown Gingivectomy, you name it!) plus a crazy 7 years of braces and access orthodontics handled my case. I am BLESSED to have found them because they handled everything with patience, skill, and the result? STUNNING! If you are worried about where to go and don’t know where to turn look no where else! I am blessed to have found them and my teeth were worth everything! Appointments are fast, easy, and informative. Just go, I literally couldn’t rave enough about this place!

Today they removed her braces and she is so so please and proud to smile now!! Back at 2 to pick up her retainer!! Thank you Crew from Access Orthodontics Weymouth!!!

We started our journey with Dr. Pham-Nguyen six years ago. My oldest daughter had a severe defect with her jaw, that with patience…. and I mean copious amounts of patience from Dr. Pham and his staff… I now have a happy and confident 18 year old. It wasn’t always easy and she had to mature a lot, as she started so young, but now she is happy and smiles so much more. Her corrective surgery was was done in Boston with a wonderful surgeon and Dr. Pham was there every step of the way. If he was away from his weymouth office and in the building during the surgery consultation and pre-op appointments, he would come right in and join us. We were not passed on to another doctor. We were shared with another doctor that Dr. Pham trusted to work with him and get the best results for my daughter. We love him. We are a year post op and braces free and visit free. For the last two years he has been my other daughter’s orthodontist and has recently begun to see my son. Every single milestone is celebrated and when the patient isn’t contributing quite the way they should be.. Dr. Pham is firm but kind. There is a joint effort between staff, patient and parent. Everyone plays a part. No staff member has a job too small and if you are looking for an orthodontist that will make the seemingly impossible happen, then the office of Dr. Pham-Nguyen and his staff, is where you want to be.

After 5 years my braces journey is finally over, thank you so much to Dr.Pham and all of the staff for being so kind and supportive, and for being amazing at what they do! My situation with my teeth was very tough and seemingly impossible but Dr.Pham was still able to help me have perfect teeth.

My daughter started here end of fifth grade and just got her braces off today… I can’t say enough about how efficient and effective and helpful access orthodontics was from helping me with insurance to their organized on time operation…my daughters teeth came out gorgeous and they really helped her take ownership of her care from brushing and elastics to encouraging her in the final stretch. We started in Weymouth because we lived south shore and ended at the Southie office because we moved… the girls at the front are awesome…would definitely recommend

My son and I both received treatment from Access Orthodontics and I can not express enough how awesome my experience was with them. I myself had braces to assist in the preparation of corrective lower jaw surgery. Dr. Khiem B. Pham-Nguyen was very responsive and collaborated my treatment with Oral & Maxillofacial Surgery at Boston Medical Center seamlessly. Evelynne who is amazing assisted Dr. Pham-Nguyen in the collaboration with Oral & Maxillofacial Surgery at Boston Medical Center. She assisted me through the whole process and kept me informed throughout my treatment. She was the main point of contact and went above and beyond her job. She was informative and compassionate and even came to visit me in the hospital after surgery. She is truly a blessing. I highly recommend Access Orthodontics when considering any orthodontic treatments.

I was a patient for almost 5 years and received quality care. Everyone that works here is super friendly and cares about giving the best treatment possible. Also, they were very flexible and offered appointment times to fit me and my busy schedule! Dr. Pham has done a great job and thanks to him and his team I have an excellent smile!

Today I got my braces off and my journey with the staff here has been amazing! They helped me make my teeth look better than I thought was possible and they were always so kind and helpful. As long as you follow directions everything will go smoothly and you will leave with perfect teeth. I would 100% recommend this place to anyone!

Honestly, I don’t know how Dr. Khiem did it because last year I went to an overnight camp for 25 days and during that time, I didn’t put on my elastics as told, so when I came back, all the progress he had made beforehand almost completely disappeared and in a span of less than 1 year, he’s got my teeth looking great. It’s crazy what kind of transformation my teeth went through in that short span of time. Right when I got my braces off, everybody noticed it and congratulated me, and it’s all thanks to the Dr. Khiem and the staff that work there. They are friendly and just the entire experience was all in all amazing, so thank you!

Dr. Pham and his staff are amazing. They have dedicated a significant amount of effort in ensuring that my teeth came out looking perfect, and I couldn’t be more pleased with my orthodontics experience. Dr. Pham has shown great care for my teeth, and I highly recommend him. He is a good and intelligent man who cares about his work.

The best decision of my life to get my braces with access orthodontics. Dr. Pham is one of the best and most knowledgeable in the field. He is super kind and friendly and overall really helpful in answering all your needs and concern regarding the process. It’s worth every penny with the service and procedure that he provides. The staff are professional and really great. The team has been great to work with. It’s been 3 years of excellent service and never once had I had any bad experiences. I can’t say enough of how great this place is. It was an honor to have DR. PHAM help make my smile great. Thank you to the team at ACCESS ORTHODONTICS

After my dentist recommended me, I started coming here in 2nd grade and my teeth were a mess. I needed two palette expanders, braces, and multiple oral surgeries. Because our insurance changed and we signed a contract in the beginning, Dr. Pham hasn’t made any money off of me in years. He’s continued to help me fix my teeth and smile out of the kindness of his heart. After everything, my teeth were finally ready to get the braces taken off when I started my senior year of high school. All the staff members; Dr. Pham, Evelynne, Jenny, Chastity, and Cali; are always so welcoming and friendly and make sure to be on top of you so you don’t miss an appointment and that you know what you’re doing. They really look out for you and want you to succeed in your orthodontic experience. Although it took 10 years for everything to come together, my family and I are really happy with the results. Highly recommend.

I was referred to Dr. Pham by my dentist because my family couldn’t afford braces for me. We had trouble getting my braces covered by our insurance since my teeth needed braces but weren’t not messed up enough to automatically be covered. After an in-depth first visit with Dr. Pham, he appealed to my insurance company many times over the course of several years about my case so that he could help me get braces. Throughout his relentless hard work, Dr. Pham finally got the appeal for the insurance company to cover my braces and my family and I were so thankful to him for pursuing my case even after years because he really did care about providing me with the best possible dental care and smile. I was a patient at Access Orthodontics for over 3 years and Dr. Pham and his staff provide exceptional care. They’re extremely friendly and kind, and I never felt that I couldn’t voice any of my worries. Dr. Pham and his staff always made sure to know how I was doing and help me if I felt discomfort or anything. They were so kind to me and my family, making sure that I received the best care and my experience with braces was as painless as possible. I 100% recommend getting braces at Access Orthodontics because Dr. Pham and his staff provide exceptional care and I’m so thankful for that and my smile!
