Jen Spencer, Owner

Coach Jen has a long history working with children and loves bringing the bus to schools and homes so your kids can have a blast while getting fit.

Before upping her game with the newly designed and thrilling Action Bus, Coach Jen brought the fun to the region for 3 years with the Tumblebus Metro Boston. She is so excited to show everyone the fun games and obstacles aboard the new Action Bus.

Having worked with children for almost 20 years, Coach Jen knows from experience what kids find fun. Jen got her start in this field at Extra Innings Baseball and Softball Training Center in Watertown. As the co-owner for seven years, managing both youth programs and birthday parties, Jen brought the fun to the center. Coach Jen created and hosted classes for the after-school program at the Wellington Elementary School in Belmont, and coached varsity basketball at Newton Country Day School and Belmont High School.

Coach Jen can’t wait to see your child on The Action Bus so they can see for themselves the fun games and obstacles inside. Coach Jen loves being a “gym teacher on wheels” and has only the best memories of her first gym teacher and her first coach. Jen would love to provide some fun, challenging, fitness successes and memories for your child and their friends.
