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.



Peak Mental Performance Coaching, LLC was founded in 2017 by Dr. Matthew Flynn, a clinical psychologist who has extensive experience in the field of clinical psychology. The creation of this performance enhancement mental health practice has been a dream of his 20 years in the making.

The summer has come and gone, schools and many sports have been in full swing for many months. Unfortunately many are still stuck and stressed, trying to cope with the unknowns of the fall and impending winter. Although in many respects it feels as if we are not moving forward, we have to remind ourselves not everything has changed, positives do lie ahead, and everyone has strengths and the ability to find resiliency to keep pushing forward. Peak Mental Performance Coaching LLC is ready to join you in the process.


Unfortunately it has been a rather uneventful few months at Peak Mental Performance Coaching, LLC in terms of change. As I say to many of my clients still stuck here at home. Despite this fact, we are dedicated to helping our clients find ways to cope and move forward in life. Telehealth continues to be an effective means of treatment. Every month we get a little closer to being back in the office, hoping to see people in person soon. Many of our clients are happy with the efficacy and convenience of this means of treatment, and will continue to do what they feel is best for them. Although the timeline to be back in the office is still unknown, we are actively seeing people and accepting new referrals..  


​While the primary focus these last couple of months has been our direct work with clients, we have been able to connect with several of our affiliations and other community contacts​, and are actively working on finding collaboration opportunities to help them, and their clients' needs. At the same time, we have talked to several new ones and hope to have more formal announcements in the near future. If you are an organization looking to expand your connections we are always excited to talk about new collaboration opportunities. 


In the meantime, check out our new Blog titled PUSH FORWARD AND FIND THE OPEN WINDOW which focuses on moving forward and taking adversity head on.
