Coach Jen

Jennifer Hamack

Jen is a former gymnast, starting at age six in her local school’s community education program until reaching high school. She is a current Safety Certified professional member of USA Gymnastics and has completed U100 - Fundamentals of Gymnastics Instruction. Jen started her coaching career with Jumpn Gymnastics beginning of 2017. She grew up and resides in the area with her three beautiful daughters aged nine, four and two, and also a fiancée. Jen had her first gymnastics coaching job at age 15.  For over ten years, she worked at several animal hospitals, assisting with everything from boarding animals to surgeries. She was a stay-at-home mom for four years until her oldest child discovered a love and passion for gymnastics and quickly became a competitive team gymnast.  Jen discovered soon after the conclusion of our first competitive season that she loved gymnastics more now than she did in school as a child, and realized that coaching recreational and team athletes is what she loves most, and by watching these young children accomplish what they worked so long for and of their achievements, that with hard work and dedication, anything is possible! We are so thrilled to have Jen as part of our Jumpn Gymnastics team!
