About Us

Meet the Doctor

Born, raised, and college-educated in Europe-Romania, I won a Diversity Visa lottery in 1995 and, with it, the right to immigrate legally to the U.S. In 1999, I earned my doctorate of dental medicine from the University of Pennsylvania, and my certificate in orthodontics from George Washington University, Washington, D.C., in 2001. I proudly served in the U.S. Army Reserve as a general dentist and Captain from 2001 to 2004. Recently, I worked again for the military as a board-certified orthodontic contractor in Kaiserslautern, Germany, during a working sabbatical. I continue to learn by annually participating in numerous orthodontic education courses to bring the latest treatment methodologies to my patients.

I love the aesthetic focus of my specialty and the complexity of the cases I take on. My niche is designing new smiles to facilitate better breathing and facial harmony. I enjoy treating complex adult cases in an interdisciplinary setting: working with general dentists, periodontists, and oral surgeons to address severe problems.

I am also helping severe OSA (obstructive sleep apnea) patients minimize their dependency on CPAP machines, improve their smiles, aachieve a more harmonious jawline, enjoy a good night’s sleep and an overall better quality of life.

In my spare time, I enjoy spending time with my three children: Julia, Alex, and Johnny. They all had expanders and braces and seem to understand my work from the patient’s point of view. You may see them at different times helping in the office with various tasks: from instrument sterilization to assisting chairside or even doing some minor landscaping. When I’m not at the office, I love to travel and experience new cultures. Trying ethnic foods, hiking, and riding my scooter off of the beaten path are among my favorite hobbies. I also enjoy DIY projects such as remodeling, gardening, cooking, streaming foreign movies, and attempting to bake cakes from scratch for my kids’ birthdays.
