Kearney praises the canoeing coaches Roland Muhlen, Andy Toro and Paul Podgorski. Toro and Podgorski were national team coaches.
Since 1986, Kearney has been the sports physiologist in the Sports Science and Technology Division of the United States Olympic Committee in Colorado Springs, Colorado. "This provides me the opportunity to focus on assisting elite level coaches and athletes (to) optimize their performances," he said. "The division programs include testing and evaluation services, athlete and coach education programs and research and development. This is an ideal position and sport has thus been an integral aspect of my personal and professional development."
