I am fortunate to have turned my passion into my life's work. My career began as a professional triathlete and business owner in the sports and recreation industry, where I competed in the IRONMAN Hawaii World Championships 8-Times and served as the OFFICIAL Coach of IRONMAN. After 17+ years of managing a leading sports performance enterprise in retail and service, I was recruited to be a national corporate team leader for a large publicly traded company in the health and fitness industry. For 10 years, I managed a team of several hundred people nationwide.
My driving force has always been helping others optimize their personal and professional performance. Today, I continue this mission as an Executive Coach and business consultant. I leverage my unique experience as an entrepreneur and corporate team leader to help clients enhance their performance. As a Certified VISTAGE Chair for nearly five years, I have guided several dozen CEOs and executives toward growth. In my role as an executive coach and leadership trainer, I work closely with high-performing business leaders to foster accountability and self-awareness.
When I am not working, I love spending time outdoors hiking, target shooting, and competing in 24-hour mountain bike racing events in the solo, single-speed division. I also cherish moments with my incredible daughters and my beautiful partner, Joy, along with her son, on our hobby farm.
“Steve Weaver has a unique ability to identify with you as a business professional as well as you as a person. That skill set has been incredibly beneficial for me as we’ve successfully worked through multiple opportunities and problems, that I could not have done on my own. Highly recommend.”
