What our clients say 

  • Thomas has made significant changes to the dynamics of our group and the individuals within, facilitating a safe, successful environment. This is key in high performance refereeing as officials are exposed to high levels of pressure and criticism. Support around performance and mental health is key for our officials and I am very grateful to have had the opportunity to work with Thomas. He has had a huge impact on our Match Officials Team, especially during this crucial year for Women´s Rugby with the Rugby World Cup hosted in New Zealand.

  • Working with Stephanie changed my life. As a young athlete, I was at a point in my life where I wasn’t even sure I wanted to continue my sport. I started meeting with Stephanie as a way to fall back in love with my sport. I earned a starting position on the team and I walked away from my sport a better human, friend, and teammate. Stephanie taught me so much about life and relationships, and helped me manage so much of my life stressors. She truly made me feel like a person not just an athlete. Every session we would peel back more layers I didn’t even know I had. The best thing about working with Stephanie was I never felt judged and I always felt heard. She came to every session prepared for whatever I threw at her. I felt so supported through it all and I am so thankful to have met Stephanie. She forever changed my life.

  • Tom has had an incredible impact on my refereeing performance as well as life off the field. His ability to listen and read behavior means that we have been able to delve deeper beyond the surface “chit chat” and deal with the real issues that has then helped me to make a consistent change. Tom’s questions and insights have helped me understand so much more about my mental performance and he’s empowered me to be able to take on whatever challenge may lie ahead.

    Aimee Barrett-Theron, International Rugby Union Referee

  • Working with Tom has been an empowering and important piece of my development as a young sport psychology professional. His knowledge and belief in his work is clear and the care he has shown towards me and my work has helped me with my own clients. If you are looking for a way to improve your life and your work, Tackle Growth is the place to go!

Mental performance consultation & mental health counseling

the Difference between Performance Consultation & Mental Health Counseling

A simple way to think about the two is that performance consultation asks “how can we improve our performance?” whereas mental health counseling asks “how can we understand our life experiences and enhance our life?”.

Mental health counseling may be related to performance, but it also relates to things outside of performance. Whereas performance consultation is specific to your performance role and performance experiences.  Although these services do overlap, below is a quick way to see the differences.
