Jonathan Guarente discovered his passion for coaching with the Northeast Philadelphia Rockers and EYBL Philadelphia Belles Nike Travel Team on the AAU girls circuit. Under his guidance, the Belles won two Mid-Atlantic Regional Championships, a USJN Hershey title and USJN DC National Championship and numerous athletes went on to attain college scholarships.

In addition to his AAU experience, Jonathan has served as a high school coach. He was an assistant at Marple Newtown, Radnor and The Westtown School. During his tenure at Westtown, he helped guide the Moose to two league titles and two state championship game appearances. He coached some of the nation’s top recruits, most notably Daniel Ochefu (Villanova), Yilret Yiljep (American University), Jared Nickens (Maryland), Edvinas Rupkus (Skidmore), Jair Bolden (South Carolina, Butler) and George Papagiannis the 13th pick in the 2016 NBA Draft.

After three successful years, Jonathan left Westtown to become head girls’ basketball coach at Collegium Charter School. In his first year, Collegium won a school-record 20 games and the first league title in any female sport. The next season, the Lady Cougars won 21 games, repeated as league champs and made their first PIAA District 1 tournament appearance in school history.

Jonathan, is taking the knowledge he gained from his 20 years on the bench to advise some of the most talented players in the area. Already heralded as one of the region’s top shooting coaches, Jonathan mentors athletes from Delaware, New Jersey, Maryland and Pennsylvania, in addition to working with prospects from nationally-ranked Westtown.

“Jonathan is an integral part of our success at Westtown,” said head coach Seth Berger. “I recommend my players go to him for high level shooting instruction. I’ve seen players make really impressive improvements and adjustments to their technique in very short periods of time. His eye for shooting mechanics is unparalleled and I consider him the best at what he does in our area.”

In the Summer of '19,  Jonathan was named head coach of the Church Farm School boys' basketball program. Coach Guarente led the Griffins to the 2021 District 1 2A championship and was named Bicentennial Athletic League Coach of the Year in 2023.
