Dental Hygienist

Gwen Duong, RDH

Gwen has been our Registered Dental Hygienist since 1997. She received a Bachelor of Science degree in biology from Virginia Commonwealth University in 1993 and a Bachelor of Science degree in dental hygiene in 1997. She focuses on two major health issues: your home care techniques and your dental fitness. Ms. Duong provides the knowledge and techniques necessary for you to maintain good oral health for a lifetime. Both our adult and child patients appreciate Gwen’s gentle and caring manner. They are comfortable under her care and therefore keep their oral hygiene care up to date. Gwen and her husband, Steve, live in Centreville, Virginia, and enjoy spending time with their son and two daughters: Cameron, Camille and Caeley.

Jill Tsiamis, RDH

Jill graduated from Oakton HS and went on to continue her bachelor’s in marketing from GMU. She completed her hygiene training from the University of MD in 1994 and worked until 2006, including part-time with Dr. LeBeau while Gwen was on maternity leave. She stayed home to raise her three children Yianni, Nikolas and Eleni, and during that time became an avid tennis player, certified personal trainer, and fitness nutrition specialist. Once her kids were in high school and college, she returned to dental hygiene and works part-time as a licensed realtor. She enjoys biking, hiking, trips to the beach, spending time with family and friends, attending concerts, and vacationing in Florida and Maine. Jill loves meeting new people and can’t wait to build relationships and care for our patients.
