At ISNation, everything starts with one belief: every athlete deserves to feel seen.

Because if you’ve ever felt like you’re carrying pressure no one else can see… you’re not the only one.

That’s why we’re proud to welcome Theresa Giunta, Certified Mental Performance Consultant (CMPC) and founder of TG Performance, to ISNation as one of our newest champions—someone who understands both the grind of competing and the mental battles athletes face every day.

About Theresa

Theresa brings something powerful to ISNation: real experience from both sides of sport.

Before she ever coached mindset, she lived it.

As a 2x All-American lacrosse player at West Chester University, competing at both midfield and defense, she understands what it feels like when the game speeds up, expectations rise, and mistakes feel bigger than they should. In 2025, she was inducted into the West Chester University Athletics Hall of Fame—a recognition of not just performance, but consistency, grit, and leadership.

But here’s what matters more: she knows the pressure, the expectations, the moments when your mind starts saying, “Am I good enough?”

That’s what led her to become a Certified Mental Performance Consultant (CMPC)—working with athletes to build confidence, handle pressure, and perform freely.

Today, Theresa works with athletes at every level:

  • Professional and national team athletes

  • Division I, II, and III programs

  • Youth and club athletes

  • Coaches, business professionals, and healthcare leaders

She also serves as a Mental Performance Coach at IMG Academy and leads her own practice, TG Performance, where she helps athletes unlock their potential by owning their mindset.

Why This Matters

Athletes today are carrying more than practices, games, and expectations.

Many are also dealing with pressure, fear of mistakes, comparison, confidence struggles, and the feeling that they have to hold it all together even when the game feels heavy. ISNation was built to face that reality. We are here for the athlete behind the performance: the person trying to stay confident, stay focused, and keep growing even when pressure starts to build.

Our platform exists to help athletes build daily habits of growth through authentic stories, expert guidance, and meaningful connection.

That is why Theresa is such a strong fit for this mission.

She understands that mental performance is not only about showing up in the biggest moments. It is about learning how to handle the everyday moments that shape an athlete’s confidence, mindset, and identity. The nervous moments before competition. The reset after a mistake. The pressure to prove yourself. The work it takes to keep believing in yourself through both success and setbacks.

Theresa brings a whole-person approach to performance. Her background in psychology, the psychology of human movement, mindfulness-based stress reduction, and yoga allows her to support athletes not just in how they compete, but in how they think, respond, recover, and grow.

What Theresa Brings to ISNation

Theresa brings ISNation another trusted voice for athletes who are learning how to handle pressure, build confidence, and stay connected to who they are beyond performance.

As a Certified Mental Performance Consultant and founder of TG Performance, she has worked with athletes across every level of sport, including professional and national team athletes, Division I, II, and III programs, youth and club athletes, and coaches.

Her experience as a two-time All-American lacrosse player gives her a powerful perspective. She knows what it feels like to compete at a high level, manage expectations, and keep showing up when the pressure rises. Her work now helps athletes develop the tools to do the same with more confidence, awareness, and trust in themselves.

Through ISNation, Theresa will help athletes strengthen the mental side of their game in a way that feels practical, personal, and connected to real sport experiences.

About TG Performance

TG Performance was created to help athletes, teams, and leaders unlock their potential by developing the mental skills needed to perform with confidence and consistency.

TG Performance focuses on areas that matter deeply in sports and life, including confidence, focus, resilience, emotional regulation, pressure management, and leadership. The team helps athletes understand what is happening in their minds and bodies so they can respond with more awareness instead of getting stuck in fear, frustration, or self-doubt.

What This Means for the ISNation Community

This collaboration is for the athletes and families we serve.

It is for the athlete who feels confident and ready. It is also for the athlete who feels nervous before games, gets stuck after mistakes, or wonders if they are good enough. It is for the moments when sport feels fun and freeing, and for the moments when pressure, comparison, and expectation feel harder to carry.

At ISNation, we want athletes to know that their worth goes far beyond how they perform.

With Theresa joining our community, we are continuing to build a space where athletes can grow as competitors and as people. A space where support is real, conversations are honest, and mental fitness becomes part of everyday development.
