In six short months, I was offered a full-time position and I have now been with Prince Frederick Dental Center 17 years. I thouroughly enjoy our relaxed, yet professional atmosphere. It seems to calm patients and make them at ease. I approach every day as a new challenge to strive for professionalism and excellence. My goal is quality dentistry while serving my patients.

I live in Saint Mary’s County with my husband, Jim (a real estate agent), my two daughters: Brittany and Madelyn, and our dog, Max. I enjoy family vacations, amusement parks, and quality family time at home. My favorite activities are watching my daughters with their many sporting events.

After sixteen years as a dental hygienist, I can still say I absolutely love what I do and enjoy getting up every day to make the smile of Southern Maryland a little brighter.
