Professional Coaching & Basketball Staff


Head CoachJimmie Parker
Jimmie’s playing career truly began after being cut from the Piccowaxen Middle School team in 8th grade. He was 6’3″ at that time and uncoordinated. When his parents asked what he wanted to do, he responded, “To become the first pick in the NBA Draft out of High School!” They responded, “Here are your three rules: don’t get in any trouble around the house, don’t get more than two C’s on your report card, and if you are not going to give 100%, get on the bus and come home.” That allowed Jimmie to dream and more importantly, fall in love with the process of becoming a professional athlete.

Head of SchoolTony Korson

Tony grew up loving and playing sports. His first memory of competitive sports was a 10U club soccer team, he wasn’t the worst player, but definitely bottom third on the team. Fast forward eight years (and a sport change later) there were a dozen division 1 players including the Maryland Gatorade State Player on that squad.  He was a late bloomer, Tony did not have any scholarship offers for baseball until late June after he already graduated high school.  He accepted an offer to play baseball at UMBC, and transferred to Florida Gulf Coast University after his first year in college.  To read more, click here.
