Tim Ringgold - Speaker, Author, Music Therapist, Professional Pickleball Athlete
The 40+ Athlete group has been SO instrumental in helping reach my goals as an athlete at this stage of my life. I rely on the knowledge pool among the members and hosts and the accountability thanks to the hosts creating goals with all of us for the year. There isn’t a single week that a new book, practice, or product isn’t discussed that I immediately benefit from. Seriously. The value of this super-focused mastermind is immense!
Allen Mostow - Music Business, Film and Television Marketing, and Metaphysics Expert
Engaging with the 40+ Athletes and the assembled passionate brothers make even 70+’ers like me motivated to jump in and thrive to be their best.

This group is both inspiring and challenging. Inspiring because they are great guys have a great time and sharing precise, great information…and challenging because they are such f*ucking health-ners that I need at least two years of nerd lessons to catch up to their expertise on body chemistry, measuring, and tracking. I consider myself on that path. I up my game every time I attend. Onward!
