Board of Directors


Tommy Zarembka

President Tommy Zarembka

Tommy has been part of the Potomac Soccer Association (PSA) community for over seven years with both of his children playing for the club. The club’s family feel, great coaches, and the relationships his children have formed make PSA a wonderful club to be a part of.

His community involvement extends to being a board member of the Global Soccer Alliance (promotes cultural exchanges between North American and African youth soccer programs and reduce barriers to play for youth in low-income African communities) as well as co-founder and President of Cornerstone Community (provides housing and community for instability housed men with a history of chronic substance abuse).

He is the Strategic Partnerships Director at Food & Friends.


Shannon Merkle

Treasurer Shannon Merkle

Shannon Merkle is a Senior Systems Analyst who works in the field of cancer research. She has two sons in Potomac soccer – a U18 senior and a U15 8th grader. The Merkles chose Potomac originally due to the strong reputation of the club. They stayed due to the fantastic coaches, wonderful friendships, and strong organization that Potomac has provided. Born and raised outside of DC, Shannon’s favorite professional sports teams include the Washington Football Club, Washington Nationals, and Washington Capitals. Additionally, they are often found donning the Maryland Pride colors to root for our Maryland Terrapins. When not on the soccer field (which isn’t very often), they can be found enjoying dinner out at local restaurants.
