Meet the owners

Lizzy and Michael took ownership of JETKids Gymnastics in 2017. They have two daughters, Payton and Ashtyn, who will often be seen around the gym on a regular basis.

Lizzy, a JET Gymnastics "lifer", has been at JET since she was a preschooler! She competed with JET, under head coach JA, all the way through Level 10 Nationals. 

Michael followed Lizzy into the gymnastics industry, and now it is a shared passion!

Together, with their daughters, they run JETKids as a family business, and have earned JETKids an undeniably great reputation!
