About Mastorakos Orthodontic Associates

A perfectionist approach to treatment planning, with x-rays projected on screen so patients understand each step before committing.

Reviews often highlight the level of detail the orthodontist brings to treatment planning, using TV-projected x-rays to walk through options and answer questions without pressure to proceed. Adult patients in particular mention being pleased with results achieved later in life, including a cross bite corrected over about a year and a half. Anxious or nervous patients and families with multiple kids in treatment also come up repeatedly, with staff noted for celebrating small milestones along the way.

We could not be happier with the care our family received at Mastorakos Orthodontics. Bot of our sons, Henry and Jack, have been patients at Mostorakos over the last 4 years. Our experience here from the first consultation to braces removal was OUTSTANDING. To start with, Dr. Bill is a class act. Friendly and knowledgeable. He takes the time to speak to parents and gives a positive outlook to your children. EVERY step was explained throughout the process by Dr. Bill and staff. Can't forget the front of office staff. The personalized attention and genuine care shown throughout their treatment has been a blessing. If you're looking for a top-notch orthodontics office that practices expertise, kindness and great results Mastorakos Orthodontics is the place to be!!!!

Dr. Bill Mastorakos is a class act! His office is thoughtfully laid out, with such a warm, inviting atmosphere. The waiting area feels so welcoming, and there are many small, special touches—from a personalized greeting placard with your name when you arrive, to complimentary items to take like mouthwash and toothpaste, to the beautiful art on the walls. His front desk staff are friendly and helpful, and scheduling a consultation was hassle-free. The entire experience was top-notch from start to finish. During my visit, Hannah guided me through the x-rays and photos with great care. Then, Dr. Bill projected detailed images onto a large TV and thoroughly explained all the treatment options. He was not only incredibly knowledgeable but also personable and genuinely caring. His passion for orthodontics is evident. There was no pressure to proceed with treatment, and he was so patient in answering all of my questions. Thank you, Dr. Bill, and your wonderful staff, for an outstanding experience!

Every single person here is exceptional. I have just gone for an initial consultation, and was met with top-notch quality, kind people. Dr Bill is very thoughtful, thorough, and as kind as can be.

If you are looking for professional orthodontics, this place is the answer. My son just got his braces off today and we both love it! Not only for kids teenagers but adult case too. I am 42 years old and my son is 14 years old, we both got our nice smile from Dr. Bill!! He is perfectionist ! Worth for the price!! I am recommended.

The entire team at MOA is welcoming and inviting, from the first phone call to the end of the appointment. We are in the early stages of my son needing orthodontic work and Dr. Bill was honest and transparent about his needs and the road ahead. I’d recommend this group to anyone needing orthodontic care in the area.
