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.

Happy fall everyone. As we enter a transition time of year, Halloween is just a few days away and the next thing you know we will be into the holiday season. Typically I love this time of year. Despite the yard work, there is always something special about jumping in the leaves, carving pumpkins, and sitting by a fire pit. Football is in full swing, hockey is getting ready to drop the puck, and the many of the other sports are deep into their seasons. While there are many exciting things going on, this can be the time of year of increased stress. People are already feeling the demands of the holidays rapidly approaching. Although students are back in the building, schools typically increase their demands at this time of year, and this year has been a unique adjustment. Whether you are an athlete, student, or general clinical psychology client, Peak Mental Performance Coaching is ready to teach you the skills to manage these many changes.

We have continued to slowly increase office hours into the fall. However, with many clients preferring to utilize telehealth, this will remain a treatment option It works well, and remains an effective method of treatment as many clients now the ability to log in from school or their sports facility. This is such an amazing option of treatment for both client and provider and really makes scheduling easier for everyone. 

As with every fall, we continue to be very busy In particular we have noticed an uptick in school anxiety, which is not a surprise with the transition back to regular school. However, on the flip side, many of the athletes we work with are excited to be back to having a normal season, enjoying fans being back in the stands, and the return of intense competition. Despite being busy we continue to take referrals on a case by case basis whether in be in the office, online, or hybrid treatment. If you know someone who is in need of support, feel free to have them contact us.

We continue to have frequent contact and consultations with TrainerMD and are now a full member of their advisory board. They have many exciting things in the works they will be rolling out for athletes in the next few months and we look forward to sharing them when the time is right. We continue building our relationship with Xcelerated Performance. Keep an eye on future newsletters as we hope to develop new programming with them over the next few months. We have other meetings coming up with other contacts in the next few and hope there will be more to share in the near future. We are always looking for new organizations to work with so reach out today to talk more.
