On the club level, the Northport resident plays soccer for the Albertson Elite Fury, the Eastern New York Olympic Development Program, the Region 1 Team (Northest United States) and she is also in the U.S. Youth National Team Player Pool. She also plays soccer for St. Anthony's High School, where she is in the National Honor Society.

"Sydney Arestivo is one of the Fury program's up and coming young talented soccer players," commented Fury head coach Michael Demakis. "She has tremendous foot skills and quickness on the ball, and is very elusive when she plays. An exceptional one-on-one player who can take players on down the line as well as to goal. Sydney will be bringing a lot of energy to the Long Island Fury."

Outside of soccer, Sydney's favorite activities are snowboarding and playing the violin.
