Kailyn Case

Assistant Coach

Hi! My name is Coach KK and I started playing volleyball in the 8th grade where I began my setting career. I made Junior Varsity my freshman year and was moved up to varsity my sophomore to senior year. I played at the local Volleyball Club on travel teams where my love for volleyball continued to grow. After high school, I continued my career of setting at Fullerton Junior College under Jason Dillard. In my sophomore year, Megan and Filip took over the program and made me fall even more in love with volleyball than ever before. This love and passion allowed me to receive a full-ride scholarship to play for Concordia University and continue pursuing the sport I love. This will be my second year as an assistant with ProPlay and I look forward to building new relationships and being apart of every player's journey.  #ProPlayFamily

Jonathan Carlson

Assistant Coach

Coach Jon is originally from Seattle, Washington.  He grew up around the sport of volleyball because his Dad and grandfather coached. He would attend their practices and see how the game was played.  When Coach Jon was 14 he traveled to San Jose for a tournament then attended the USA tryout after. He made the top tier for the age group which opened the door for him to join two youth national training teams at the age of 16 and 17.  As a Junior in high school, Coach Jon committed to California Baptist University but unfortunately CBU terminated their program during his Senior year. 

Coach Jon is currently attending Concordia Irvine where he has been starting as their Outside Hitter.  This is his first year as a ProPlay coach and he is stoked to be apart of this family!
