Hailey is originally from Portland, Oregon. Growing up, Hailey played for Nike Northwest Juniors and went to the Junior National Championships every year. During her senior year, her team finished 5th in the 18 Open division at JNs. Hailey was then recruited to be a libero at Cal State Stanislaus, which brought Hailey down here to Northern California. As a 4 year starting libero and captain at CSU, Hailey racked up over 1,000 digs and lead the team in serving aces. Throughout her college career, Hailey coached at Rage Volleyball Club in Ripon, CA, assisting the 13-1 team who qualified for JNs and head coaching the 16-3 team, just shy of a bid. Even a 3s team was competitive and a top team in NCVA. Hailey also head coached a 13s premier team in Fresno, CA who ended the season undefeated at league tournaments.

Hailey’s coaching philosophy all roots from hard work. She has learned very early on that it is not the most talented team that wins championships, but the team that never quits. Any kid with a good attitude, work ethic and determination to get better is someone Hailey wants on her team.

Hailey currently lives in the city and working at a hedge fund. Her time spent outside of coaching volleyball is playing outdoor volleyball (sand or grass), traveling and shopping! Hailey can’t wait to get this club season going!
