 Coach Greg

ADHL Head Coach and 10U Bucks Head Coach - Greg Sitrick

Coach Greg Sitrick has played hockey just about his entire life.  He played forward until high school and then switched to goalie his freshman year.  Coach Sitrick played at all levels growing up - house, travel and club hockey - and continued to play hockey throughout college and law school at the University of Illinois at Chicago (Flames), Northern Arizona University, and Northwestern University. He has also coached hockey at a variety of levels.  After graduating law school, he continued with the Northwestern University program by coaching them for 6 years. For the last 8 years, Coach Sitrick has been sharing his knowledge with a variety of Arizona youth hockey teams and players, in the hopes that the kids will be provided with the knowledge and opportunities to develop to their full potential. After coaching a number of House League All Star teams, Coach Sitrick recognized the need for the continued development of some of the more advanced house league players, and began holding one day clinics to give those players the knowledge and opportunities they were hungry for but were not getting from the regular house league program.   

Coach Sitrick has coached a lot of kids that have played, or currently play travel hockey around the Valley, and he continues to feed new kids to the travel programs each year. He draws upon his vast experiences to provide constructive, targeted, individualized feedback for his players and goalies so that they can succeed in their journey to becoming the best player they can be.
