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. 


Sport Psychology

Mental toughness is key to successful athletic performance and can be the difference between winning and losing. Struggling with anxiety and emotion management? Confidence or motivation challenges? 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.

The fall is certainly here as the leaves are changing, the weather is chillier, and the days are becoming shorter. As predicted the fall is always our busiest time of year. Sports have switched over, school is at full speed, and it just seems there is more to do in less time, not just for us, but everyone. It is at this time that it is important to use many different skills to manage stress and our relationships with others. Are you ready to learn more of them? Peak Mental Performance Coaching LLC is ready to help you.

As we said things have been busier as with the transition into fall. We have had the opportunity to meet many new clients recently and expand our approaches and teach new skills to manage this transition time of year. At the same time, we are still applying our own lessons from the summer and finding time to mentally rest and just slowing down to be in the moment with friends and family. It is such an overlooked strategy to manage stress.


As always we continue to work closely with TrainerMD. We have been involved in continuing to help them develop their programming that centers on optimized lifestyle living, starting with the their new Athlete Safety and Performance Programming.
