Educational and Test Prep Coaching

In today's world there is more pressure than ever to be successful on taking standardized tests whether it be the SATs, PSATs, GREs, school exams, or licensing. Anxiety and frustrations with the testing process can hurt performance, contribute to family conflicts, and derail confidence. Peak Mental Performance Coaching, LLC  can help teach you to manage these emotions and perform at your optimal level.

Preparing to compete at the next level? Recovering from an injury or transitioning out of the world of sports? Peak Mental Performance Coaching, LLC works with athletes of all skill levels, ages, and sports to  develop individualized plans and learn the mental skills necessary to overcome mental blocks and enhance athletic performance.

We were excited to hear that our first connection Athletic Evolution is expanding and moving to a new location. We can't wait to get there and see the new place in person The same is true for High End Hockey, who are rebranding as Elev802 Boston, and also expanding. These two programs will be adding many new exciting resources to the community and we are excited to join in the process.
