DO, CSCS, aka "Dr. Meathead"

Seth is a current amateur strength athlete who has been involved in the world of strength sports since 2012. Although primarily competing as a nationally-qualified middleweight strongman, he also competes in powerlifting and the highland games, tallying multiple victories in all three sports in over 20 contests. Prior to his time as a strength athlete, Seth is a former NCAA football player, triathlete and obstacle racer.

Seth's background in multiple athletic disciplines has helped shape the way he approaches his high-performance coaching. He believes that there are very few “useless” exercises, as nearly any movement can have a place in an athlete's program, depending on his or her goals. Success in sport and prevention of injury requires a holistic and balanced approach that uses every tool in the toolbox. Given his experience training for and coaching a variety of sports, this is exactly how Seth attacks his clients' goals.

Also known as “Dr. Meathead,” Seth is a board-certified family physician with a focus in lifestyle and musculoskeletal medicine, nutrition, and corrective exercise. Just as he uses strength and conditioning principles to treat the ailments of his patients, he uses his extensive training in functional anatomy and biological sciences to prescribe the correct program for each of his clients. Lifestyle habits, nutrition, and injury history are important considerations to be made when designing and applying a program to any athlete, and Seth is well-equipped to deal with any combination of these.
