Brendan grew up in Texas playing every sport his school offered. He chose to pursue hockey and played in high school and college. He still enjoys playing hockey, soccer, and softball, and thinks playing in the Seattle mist is way better than the Texas heat.  He's always looking for more opportunities for a good pick up game. While in law school, Brendan was the president of the Health and Wellness Association, which promoted healthy mental and physical fitness on campus. 


Brendan has a passion for encouraging people to set motivating goals, helping them reach those goals, and working to improve their overall health as a part of the process. He loves assisting people as they prove to themselves all they are capable of achieving. Brendan is excited to be a part of this team as it works together with support and encouragement to help everyone meet their goals.
