Collin Gillespie, the skilled NBA player for the Phoenix Suns, attributes his success to the supportive family that has shaped his journey in the league.
For Collin, that foundation starts with his parents, Jim and Therese Gillespie, whose continuous support and love have been a constant presence both on and off the court.
Collin was born on June 25, 1999, in Huntingdon Valley, Pennsylvania, a peaceful suburb located just outside of Philadelphia.
He grew up as the youngest of three siblings in a tight-knit family of five.
His father, Jim Gillespie, now 58, is a veteran lieutenant with the Philadelphia Police Department.
With years of service under his belt, Jim has spent his career protecting the streets of Philly. This job demands strength and dedication, qualities he undoubtedly passed down to his children.
Collin’s mother, Therese Gillespie, is a CAT scan technician at Lower Bucks Hospital, with previous experience at Redeemer Health.
Therese’s caring nature is evident both in her professional work and in her family life.
She was raised in a family of four siblings: Susanne Fahy Argentina, Dan Fahy Jr., and Mary Fahy.
She attended Archbishop Ryan High School in Philadelphia, where her roots in the community took hold.
Together, Jim and Therese built a home filled with love, discipline, and encouragement, creating the perfect environment for Collin and his siblings to thrive.
Collin Wasn’t The Only Athlete In The Gillespie Family
Collin’s older sister, Victoria, also made a splash as a swimmer at the University of Delaware, showcasing her dedication to sports.
His brother, James, followed a path closer to Collin’s, playing basketball and studying at Widener University.
Growing up with two athletic siblings likely fueled Collin’s competitive spirit, as the Gillespie household buzzed with energy and a shared passion for sports.
Whether it was cheering Victoria on at swim meets or shooting hoops with James in the driveway, Collin’s childhood was steeped in activity.
Jim and Therese were always there, balancing busy careers with sideline support, creating an environment where their kids could chase their dreams without fear of failure.
Jim and Therese have been more than just spectators in Collin’s journey; they’ve been his biggest fans and most regular anchors.
From his early days dominating at Archbishop Wood High School to his standout college career at Villanova University, where he earned the Big East Player of the Year title in 2022, his parents were a constant presence.
That support didn’t waver as Collin took his talents to the pros.
Collin’s professional career kicked off in the 2022 NBA Draft when he signed a two-way contract with the Denver Nuggets.
Though undrafted, his tenacity earned him a spot, and his parents were there to celebrate every milestone.
Fast forward to July 2, 2024, when Collin inked another two-way deal, this time with the Phoenix Suns. Jim and Therese glowed with pride as their son took the next step in his NBA journey.
Their support isn’t just for the big moments, either. Whether it’s attending games, sharing quiet family times, or offering words of encouragement after a tough loss, Collin’s parents show up.
A Standout Moment In The Suns’ Spotlight
Collin’s work ethic, undoubtedly shaped by Jim’s discipline and Therese’s care, shone brightly in a recent game on March 19, 2025.
Stepping into the starting lineup for an injured Bradley Beal, Collin helped the Suns secure a 127-121 win over the Chicago Bulls, extending their winning streak to three games.
The most recent game was on March 26, 2025, at the Footprint Center, marking the Suns’ first clash with Boston this season.
His stability, playmaking, and defensive hustle kept Phoenix rolling, proving he’s more than ready for the NBA stage.
Suns fans couldn’t help but notice that Gillespie sparks a mix of nerve and heart that echoes the values Jim and Therese established in him.
With Collin starting, the Suns remain undefeated, and his parents were likely cheering from the stands or glued to the TV back home, proud as ever.
