Denise Dombay  - SwimLabs Montgomery County Owner and Competitive Coach


Denise started swimming almost before she could walk. Her mom was an instructor and coach at the local YMCA and Denise and her sister grew up around the pool—taking lessons, playing with friends, practicing with the swim team, and eventually lifeguarding, teaching, and coaching. She swam through college, graduating from The George Washington University (GWU) as a Division 1 athlete and budding accountant. After a long and successful corporate career in the DC area, and raising two amazing teens, Denise decided to return to her two loves—swimming and coaching. She still swims and regularly competes in Masters swim meets, holding several Top 10 times for her age group. She’s a proud member of the Germantown Masters swim team, and she also participates in open water swims, including the Great Chesapeake Bay Swim. The June 2018 event will mark her 10th year of “crossing the Bay”. Denise is still involved with GWU, as a member of the Business School Board of Advisors and as a member of the Athletic Advisory Council. She is also serves on the Board of the Capital Area Food Bank. Now she’s hoping to share her passion for swimming with others!
