Very friendly staff! Dr Flanagan was amazing! He gave honest evaluation of my son's teeth, where I felt another Ortho just wanted to put him into... braces for the money.read more

Dr. Flanagan does amazing work. My sons teeth turned out amazing and we are about to start 2 more in his program. The lifetime retainers has been a... life saver. My son managed to lose 3 retainers in one week, all were replaced at no charge and they even worked with him to make a plan on how to not lose anymore. Pricing is comparable to the areas pricing. Friendly staff and a fun program for the kids.read more
