Spring is here, and the bouncing between chilly and nice days is evidence of this fact. We can feel we are on the cusp of the really nice weather which is exciting. This is a time of year that can start to feel energized and optimistic, but a little restless waiting for it to come. It is a time of transition and change, which can add to unsettling feelings or anxiety. Peak Mental Performance Coaching LLC is ready to help you manage and embrace this change.

What We Have Been Up To

On a day to day basis we continue to work with many clients with a diverse set of mental health needs. It is interesting how different transitions and time of year can impact various mental health themes. While not going into specifics, it has given us a chance to keep expanding those we work and push our own use of numerous intervention approaches. The observed positive results so far have been motivating and rewarding.


In our limited time we continue to reach out to many programs and organization to share our work and support others. We hope to continue to keep doing this.
