Welcome to summer. The days are longer and warmer. Many people are planning summer vacations or activities with friends and family. For these people, anxiety and stress is improved as everyone takes the next few months to recharge and have some fun. However, for others, there is still a lot to do and a limited time to get it all done, and they struggle to slow their mind down and enjoy the break. Peak Mental Performance Coaching LLC is ready to help you learn the skills to take advantage of this time of year and enjoy being in the moment.

What We Have Been Up To

Thankfully things with clients have slowed down a little with the transition into summer. Even we know the importance of daily self care and keeping balance in life. That being said, the work itself does remain busy as we teach clients to do the same. Without providing too much details, we have been learning and looking into new theories and concepts and applying them to our work. It is always smart to keep a learning and growth mindset.


We continue to reach out and have discussions with various programs and organizations. Most notably we have been doing close work with Athletic Evolution, one of our best and most consistent organizations we work with. In June we gave two talks for them. The first was educating their interns on the field of sport psychology, and the second more specifically focused on running a support group for athletes on the mental challenges of overcoming ACL knee injuries. Both were fun and informative not just for the athletes in attendance, but us as well. We look forward to future talks with them on similar topics and will keep you posted.


We continue to work closely as an advisor for TrainerMD. Feel free to follow me on X/Twitter at @mflynnpeakmpc for updates on the work both we and they are doing to help others manage their physical and mental health. It is exciting work and new supports for individual clients and organizations are being developed everyday.

We continue to be in the office several days per week for in person treatment, and continue to offer telehealth services to all clients. We work hard to tailor the schedule to what we believe best meets the needs of all clients. Referrals continue to be taken on a case by case basis, but feel free to reach out directly or complete the New Client Match Questionnaire on the practice website,, to see what Peak Mental Performance Coaching LLC can do for you.
