About M. Marie Dang, DMD, MS, PA

Dr. M Marie Dang handles complex cases herself, including palate expanders and Invisalign plans she manually revises, and reviewers say she saved teeth another orthodontist wanted extracted.

Dr. M Marie Dang draws particular praise for hands-on involvement in complex cases, from combining palate expanders with frenulum procedures to personally reviewing and adjusting Invisalign plans rather than leaving that to software. Several reviews describe her correcting significant issues like severe underbites, and even saving teeth another orthodontist had recommended pulling. Many families bring multiple children through treatment here, and results are described as lasting well beyond the braces coming off. Scheduling tends to run smoothly, with little wait time and flexibility around school and work.

Dr. Dang is a pleasure to work with. She is very thorough and makes sure her patients stay on top of a consistent cleaning routine, which really helps prevent plaque buildup and keeps everything on track throughout the treatment process. She takes the time to ensure there are no issues with the braces, and everything progresses smoothly. She is also very gentle and genuinely caring, which makes a big difference—especially for kids. I would highly recommend her to anyone looking for a knowledgeable and compassionate orthodontist.Thanks for everyrhing Kostas and Isaiah.

We had an excellent experience with Dr. Dang and highly recommend her. My son is not the easiest patient, and he needed oral surgery for a palate expander and a frenulum procedure ahead of braces. Dr. Dang was incredibly patient and steady throughout, guiding us carefully through what can be a tedious and complicated process. Because my son was already a teenager, timing with his growth plate was critical. I had initially consulted another well-known orthodontist, but chose Dr. Dang because of her thoughtful, thorough approach and commitment to doing things the right way for long-lasting results. Happily, my son’s braces are now off and he has a terrific smile. Dr. Dang truly cares about her patients and is passionate about her work. We are so grateful we found her.

Dr. Dang is very knowledgeable and attentive to your needs. My daughter just got her braces off after 2 years. Her teeth look amazing and my daughter is very pleased with her results. She has to continue wearing a retainer and eventually get implants put in but Dr. Dang has been very thorough and has explained to us the next step. Doctor Dang is very honest and will tell you exactly what you need to accomplish for the best results.

Our experience with Dr. Dang has been wonderful from day one. She is not only a highly skilled clinician, but also patient in her approach. She is knowledgeable, compassionate, and excellent at explaining all the details that are part of the process to both her clients and their parents. Her commitment to her patients is obvious in every interaction. So thankful for such a great result!
