“A leader by nature and a young man who holds himself and his teammates to the highest standard. He leads by example through his work ethic, discipline, and competitiveness, a true role model of what it means to be a St. Mark’s Swimmer and Student-Athlete. A top producer for the team at SPC, a multisport athlete who is now an 8-year letter winner and 4-time team MVP. A champion in the 200 Freestyle, 100 Freestyle, 200 Freestyle Relay, and 400 Freestyle Relay as a Senior. On behalf of the coaching staff and entire team, I am very proud to award the 2021 Swimming Team MVP Plaque for the second year in a row to Leo Ohannessian.”
