Basketball might have begun in the United States, but the game led Jim Cantamessa on an international path.

Born in Beaver Falls, PA, Jim attended Blackhawk High School, where he was a standout player on the court under the leadership of Beaver County Sports Hall of Famer John Miller. In the 1990s, during Blackhawk's dominant era in basketball, Jim helped lead the Cougars to a WPIAL title in 1996 and PIAA titles in 1995 and 1996. Jim led Blackhawk with 24 points in the WPIAL 1996 title game, scored 12 points in the 1995 PIAA title game, and scored 30 points in the 1996 PIAA title game. Jim also made the Pittsburgh Post-Gazette's 1996 Fab Five team.

Following his impressive high school career, 6'-8" Jim was a star for the Siena College men's basketball team from 1996 to 2000, scoring 1,316 points and compiling 535 rebounds and 229 assists across 120 games. Jim was All-MAAC second team as a sophomore and All-MAAC third team as a junior and senior, plus MAAC All-Tournament as a junior and senior. As of 2022, Jim is still in the Siena men's basketball record book: first all-time in season 3-point percentage (.564), second all-time in career 3-point percentage (.449), and sixth all-time in total 3-pointers (197). In 1997, Jim had the highest 3-point shooting percentage in the NCAA (.564) among qualifiers who had an average of at least two 3-pointers per game.

After graduating from college, Jim played basketball professionally in Europe from 2000 to 2008, for Rouen in France, FC Porto in Portugal, s.Oliver Würzburg in Germany, Reims Champagne Basket in France, and Euphony Bree and Dexia Mons-Hainaut in Belgium. In 2005, Jim helped Bree to their first-ever league title, which qualified Bree for the FIBA Supercup for the first time in the team's history. In 2008, Jim was selected for the FIBA EuroCup All-Star Game.

In 2010, Jim transitioned his playing excellence into a leadership role as a coach at Greensboro College and, for the next 13 seasons, he was instrumental in improving their men's basketball team, first as an assistant coach, then as associate head coach, and for four seasons as the Pride's head coach. Jim also served as Greensboro's head men's golf coach for seven years, leading his team to three NCAA Division III tournament appearances.

Since 2023, Jim has been the assistant men's basketball coach at Eckerd College. Jim is married to Kara Bitar, who is also from Beaver Falls, and they live in St. Petersburg, Florida.
