Mark Van Voorst Head Coach & Coach-High School & Senior

Coach Mark started swimming competitively for the Fallbrook Area Swim Team (FAST) when he was in 6th grade and continued swimming competitivley though middle school, high school, and college. During this time he was also very invloved in Water Polo. He was apart of the team that won the San Diego CIF Championships in 1978 and the runner up in 1979. While in high school, Coach Mark qualified and competed in the CIF San Diego Swim and Dive Championships all four years. He still remembers his 100 backstroke time of 56.1 seconds. Coach Mark continued his aquatic career by playing water polo at the Junior College level at Palomar College and then moving onto Cal Poly San Luis Obispo. While at Cal Poly, he was part of the Wheelman (a competitive cycling team) and competing in road races and criterions regionally. 

After graduating from Cal Poly, Coach Mark coached a multitude of sports and activities in the schools he has taught in or been invloved in adminstration for. These include boys basketball, baseball, softball, robotics, chess, and track. 

Coach Mark moved to Yuma in 2012 and started coaching for Kofa High School. In his first few years there, he had 21 swimmers on the team. In the six years leading the program, there are now over 50 swimmers on the team. He is very proud of this as he sees how the introduction of swimming in many of these new swimmers expands their involvment in school, improves grades, attendance, and the enjoyment of the high school experience. 

When Coach Mark became the Head Coach for the Yuma Heat in 2015, the club was in the midst of some challenging times. The team was stuggling to have swimmers meet Junior Olympic time standards. In conjunction with an amaing set of board members, strong and continued support of parents, coaches who really care about the athlete, the Yuma Heat had its most successful year in team history. The 2018 short course season saw the team send the most swimmers in team history to the Arizona Junior Olympics, the second most swimmers in team history to the Arizona Age Group State Championship, 7 athletes to the Far Western Championships in Santa Clara, CA., and the team even sent one swimmer to Speedo Sectionals. Coach Mark won the Arizona Swimming Age Group Coach of the year in 2018. 

The future is looking bright and he continues to look for even bigger accomplishments as the Heat program expands.
