Piranha Coaching Staff

Jason Memont
Head Coach, Competitive Swimming

Jason Memont has been involved in competitive aquatics his whole life. He began as a swimmer at the Haverhill YMCA in Massachusetts when he was five years old, eventually competing at YMCA nationals. After high school he went on to compete and set school records at Rochester Institute of Technology in New York.  After graduating from RIT, Jason returned to Massachusetts and began his coaching career at YMCA of the North Shore for just under three seasons. After sending multiple swimmers to nationals and NCAA Division One programs, he began a long collegiate coaching career beginning at The College of William and Mary. In his three years at WM, the record boards were rewritten and he coached multiple conference championships. In 2007, the women’s team won the first ever conference team title.
After W&M, Jason coached for seven years as the Associate Head Coach at University of South Carolina in the SEC. Coaching highlights during that tenure include conference record holders, a World University Games participant, and two World Championship participants. One of his swimmers was also a 2012 US Olympic Team Trials Finalist and finished that year ranked within the top-50 rankings in the world of 200m Butterfly.
Following USC, Jason was named the head coach at UNCW in North Carolina. In his six seasons as the head coach the team routinely set school records and climbed the conference standings. He coached two US Open finalists in 2019 and many swimmers achieved NCAA B-cuts.
When not at the pool, Jason enjoys cycling and running as well as spending time with his wife, Tara, and their three dogs.
