Dr. Radu is proud to offer free consultations for patients of all ages, with many orthodontic treatment options, individualized to everyone’s lifestyle and needs.

Born, raised and college educated in Europe-Romania, Dr. Radu won a diversity visa lottery in 1995 and with it, the right to legally immigrate to the US. She served her new country as a dentist and captain in the US Army Reserves from 2001-2004 and again as an orthodontist contractor in Germany between 2015 and 2016 during a working sabbatical. Upon her return, she decided to branch into a specialty clinic and add another specialist to her practice, providing periodontal services.

An open-minded clinician, Dr. Radu is committed to providing outstanding service for her patients and is always incorporating new techniques. Dr. Radu attends numerous orthodontic education courses and limits her practice to orthodontics exclusively. She is a Certified Provider for Invisalign®, Invisalign Teen and Clear Correct. Dr. Radu enjoys treating complex interdisciplinary cases such as combined orthodontics with jaw surgery and “Wilckodontics” (periodontally accelerated orthodontics) and incorporates routinely laser procedures and mini-implants that facilitate faster and more predictable orthodontic treatment results.

In her spare time, Dr. Radu takes great pride in taking care of her patients and her three children, Julia, Alex and Johnny.
