The Mullen Family Ortho Difference

We get it – teenagers sometimes lose or stop wearing their retainers. Our Smile Guarantee will make sure they enter adulthood with a stunning smile – no questions asked.
We offer free consultations to educate each patient and family in a friendly, no-pressure environment. We accept all major dental insurance plans and offer zero-interest, flexible payment plans.
Our preference whenever possible is to consolidate child/adolescent treatment into one comprehensive phase to save you time and money.
We never want finances to dissuade patients from getting the treatment that is most ideal for their particular smile, which is why we provide our aligner treatment for the same price as braces.

“Dr. Mullen and his amazing staff are absolutely wonderful. My wife and I were very worried needing to get orthodontic work done on our 7 year old. Dr. Mullen and his staff catered to our daughter. They explained every little detail throughly and put our minds at ease. Our daughter asked questions and the staff was very understanding to her needs and worries. Any hint of discomfort and the staff immediately addressed our concerns. We would 110% recommend him over and over again.

“I was fortunate enough to be treated under Dr. Mullen’s expertise, who had taken on a unique odontoma case in the upper gums, and executed the alignment process for my teeth in exceptional fashion. For me, Dr. Mullen stood out amongst a variety of orthodontists for the genuine care he held for his patients and his commitment to perfection. Due to his noteworthy skill, intuition, and, initiative, we were able to complete the treatment process months earlier than estimated.”
