Hello I'm Coach Cooper O'Brien,
I'm from St Charles and started playing lacrosse in the 4th grade. I played Attack for the combined east/north highschools, all 4 years and graduated in 2010.
I went to college at Aurora University where I competed for the Spartans' first year lacrosse program in 2011 and then all 4 years after. I played Attack and Defensive midfield. We achieved two NCAA second round tournament appearances.
Since 2014 Ive had alot of fun coaching with River City for all age groups from 8u through 14u including select and academy. I enjoy sharing my experience and interest in lacrosse while inspiring others of all levels to the sport. I believe in coaching fundamental skills as second nature. I believe in teaching life lessons, doing what's right, respect, and competition.
Outside of lacrosse I work in accounting and finance. I enjoy computers, playing guitar, and spending time with friends and family.
