Coach Doyle is the former Head Strength And Conditioning Coach of Trinity College in Hartford, CT as well the current Healthy Body Healthy Minds Curriculum Coordinator for the Town of Cromwell Public School System

Coach Doyle has had a lifelong passion for athletics and competition. A Hartford native, Kevin played football, track and lacrosse in high school and prep school at Northwest Catholic High School and Suffield Academy. He played football during his college years at Assumption College. He was also a competitive power lifter until 2006.

In 2003, he became a strength and conditioning coach at Northwest Catholic High School. During his time with the school, Kevin helped coach their football team to five consecutive conference titles. The members of his team were recognized as the best conditioned high school athletes by a study conducted by the UCONN Kinesiology department in association with Gatorade.

In 2005, Kevin became a NASM (National Academy of Sports Medicine) certified personal trainer. While working at Northwest Catholic High School, Kevin ran his FASST (Functional Athletic Strength and Speed Training) sport specific training camps for athletes from 5th grade up through college level. In 2009, Kevin earned his purple belt under Fabiano Teles with a hard-fought 1st place finish at the 1st Connecticut Brazilian Jiu-Jitsu Open Tournament.

In June 2011, Kevin went to become a Level 1 CrossFit Instructor. He realized that CrossFit was the most effective method to train the students at Underdog Brazilian Jiu-Jitsu, the gym which he co-owned. Soon after receiving his certification, Coach Doyle established CrossFit Hartford, a CrossFit Affiliate in the same building as Underdog.

In January 2014, Coach Doyle was invited to attend an exclusive Weightlifting seminar at the Olympic Training Center in Colorado Springs, and later that year he would go on to coach Juan Russo to Collegiate Nationals for Weightlifting. Doyle has traveled to train with high level coaches, including Dmitry Klokov and Vasily Polovnokov.
