E.O. Smith science students have been active in a
coral reef conservation project, propagating and maintaining a reef aquarium so students can learn about aquaculture, marine biology and reef ecosystems. E.O. Smith has hosted the New England Frag Farmer's Market for fifteen years, and it has become the biggest one-day coral event in the country, with over 1,500 attendees in 2019. E.O. Smith soccer has an impressive record. The boys soccer coach for forty years, John Blomstrann, has led the teams to more wins than any other coach in Connecticut history. From 1980 to 2020, Blomstrann coached the teams to 565 victories. During a three-year period from 1980 to 1983, the boys' soccer team won all but two games in the Eastern Connecticut Conference. The girls' 2014 season was disrupted when the team's coach, Jeffrey Sirois, sent an "inappropriate" video via
Snapchat to the young players on his team, for which he was arrested and fired. Among its most successful soccer alumni are E.O. Smith players
Eleni Benson and
Lyle Yorks. Benson was a three time all-conference selection and was named All-New England and all-state as a high school senior. She played for
Yale University, and was a defender for
Greece women's national team in the
2004 Olympics.
Lyle Yorks was one of the most highly decorated youth players in Connecticut. Yorks won two
NCAA championships with the
University of Virginia team, and then went on to a career in
Major League Soccer. The team practices at Coventry Lake (
Wangumbaug Lake) in the town of
Coventry, where it shares a boathouse at with the
UConn Huskies rowing team and uses some of the college's equipment. Several E. O. Smith actors have also won individual awards for their performances in the shows or in the Connecticut Drama Association Monologue Contest. The school has had competitive computer science and math teams since the early 1980s. ==Notable alumni==
