A member of the CSI coaching staff since 2015, Anastasia Nicholson is primarily charged with coaching CSI's accomplished group of divers on both the men's and women's sides. This includes both the one-meter and three-meter boards.  She has coached her units to a sweep of gold medals at the CUNYAC Championships each year.

A former accomplished swimmer at NCAA Division I St. Francis College from 2010-14, she served as a lifeguard during her undergraduate stay, holding swim lessons as well.  Beginning in 2011, Nicholson became a coach at the Great Kills Swim Club on Staten Island, where she directs, teaches, and coaches swimming and diving for area youths ages 5-18.  She has done similar coaching with the NYC Parks Department at Lyons Pool with stops at Our Lady Star of the Sea, and South Shore Swim Club.

Alongside her coaching duties at CSI, Nicholson is also a Pool Supervisor during off-coaching hours and served as administrative assistant at New York City's prestigious Trinity Boxing Club.
