Jonathan Kronberg has been actively involved in Ann Arbor and surrounding communities for the past decade. After four years of serving in the United States Coast Guard Jonathan moved back to Ann Arbor. Since then he has created multiple businesses ranging from a mobile & web design firm to a custom home remodeling company. But, out of all his endeavors O3 Sports is where he finds his true joy: Coaching.
In the Fall of 2016, Jonathan opened the O3 Sports Complex and then in the Fall of 2017 he opened O3 Strength & CrossFit 1on1. Both are located in Saline, MI. Jonathan says, "O3 was built as a platform to share my passion for coaching and help shape athletes for life. From youth to adult athletes, I want O3 to be a platform for people to come together and support each other no matter their background."
The Carr Family and Jonathan were introduced to each other while coaching CJ in Football almost a decade ago. Since Chad's diagnoses Jonathan he has tried to support the Carr's, and their cause, any way he can. Jonathan is honored to be part of the 2019 Dancing with the Michigan Stars and assist the Chad Tough Foundations mission of raising awareness and finding a cure for DIPG.
