Terry Parker
Assistant Coach,

2019 - present

Terry Parker grew up in Garden Grove and attended Golden West College where she played varsity field hockey for two years.  She received an athletic scholarship to CSULB where her teams won the 1979 AIAW National Championship.  Terry graduated with a BS in Microbiology.


She then worked for Beckman Instruments as a scientist doing product development for 14 years.  During this time she also did two walk-on field hockey varsity coaching stints, first at Foothill for three seasons in the late 70's and then for Westminster HS (her alma mater) also for three seasons in the early 90's.


While attending CSULB, Terry was exposed to the game of lacrosse in the off season.  Her college club lax team competed against other college clubs such as San Diego, Claremont, Whittier, and Stanford.   This was the start of women's lacrosse as a college sport that eventually became what it is today. Terry also started umpiring both field hockey and lax games and continued as an active umpire for the next 35 years.

Terry was inducted into the OC Chapter of the US Lacrosse Hall of Fame in 2008, for her career recognition as a player and leader.


In May 2017, after 21 years of service with Medtronic as a Production Chemist in the manufacturing of implantable devices (heart valves), Terry retired, which is why she has the pleasure to help coach the girls' varsity team.
