Ellie Gaug, RDH

A proud native of Huntingtown, MD, I have been working at Prince Frederick Dental Center since I graduated Dental Hygiene school in 2016. I began working as a temp, filling in when needed and was happy to start full time in May of 2018. Funny enough, my very first day working as a hygienist was here at PFDC on the same day as my graduation party!

I have three siblings and am very close with my family. When purchasing my own house, I made sure to only move 15 minutes away.

I obtained my Bachelor’s of Science in Dental Hygiene from Old Dominion University and graduated summa cum laude.
I love to travel and take road trips, especially to be outdoors and go hiking. My favorite hobby is taking care of my two cats!

In six short months, I was offered a full-time position and I have now been with Prince Frederick Dental Center for over 17 years. I thoroughly 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 activityis watching my daughters with their many sporting events.

After over 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.

I genuinely care for people. I am very happy to have the opportunity to see patients and enjoy the chance to educate and help them understand the importance of oral health.
