TC COSTELLO
Senior Director of Athlete Development at JTCC
At JTCC, we believe excellence isn’t measured by a single standard. It’s not just about trophies, rankings, or perfect serves. Excellence is deeply personal—as unique as every individual who walks through our doors.
For over 15 years, JTCC has been the DMV’s only tennis organization where a future college player trains alongside a grandmother learning her first forehand, where a wheelchair athlete perfects their serve next to a five-year-old in pre-rally, where a CEO and a scholarship student become doubles partners. This remarkable simultaneity—all programs, all people, all in one place—creates an environment where excellence takes countless forms.
The “Define Your Excellence” campaign celebrates this fundamental truth: at JTCC, you don’t pursue someone else’s definition of success. You create your own.

Did you know that JTCC has more women than men coaches on the developmental side?! 🎾
We caught up with them and asked a series of fun questions and also the significance of working with so many female coaches.
Shoutout to all the amazing work they do! 👏

Excellence looks different for everyone at JTCC.
It’s not just about trophies or rankings...
It’s about the retiree learning their first forehand. The wheelchair athlete perfecting their serve. The five-year-old discovering tennis for the first time. The scholarship student becoming doubles partners with the CEO.
For more than 15 years, JTCC has been the only place in the DMV where all of this happens under one roof, where future college players train alongside beginners, where every program and every person comes together.
Your support helps us create a place where everyone can pursue their own definition of success. Every dollar matters. Every dollar defines excellence.

Coaches change lives. 💙
JTCC’s Gabby Hesse, Head of Wheelchair & Adaptive Tennis, was featured on FOX 5 DC’s Live Zone recently as part of Coach Appreciation Month.
Gabby shared how she’s leading the charge to make tennis accessible for players of all abilities — proving great coaches don’t just build athletes, they build confidence, character, and community. 💪🎾
Great job representing JTCC Gabby!
