Mobile Gymnastics Classes for Kids in Seattle
We are a mobile gymnastics company that has been serving Washington State for over 20 years. Our mission is to provide a positive physical and psychological experience to every child through sound, basic tumbling and gymnastic skills taught in a fun, non-competitive environment. We believe encouragement and positive motivation are keys to a child's achievement and self-confidence. Our programs are offered at daycares, preschools, athletic clubs, dance studios, private schools, home school cooperatives, and elementary schools. We teach all year long, offering summer camps and birthday parties. Our coaches are experienced, CPR and First Aid certified, and receive continuing education on gymnastics coaching and childhood development.

We serve the Greater Seattle Area, including North Bend, Snoqualmie, Fall City, Redmond, Carnation, Duvall, Issaquah, and Bellevue. Our programs cater to children aged 2-12, with specialized offerings for preschool, grade school, parkour, and special events. We prioritize safety, inclusivity, and community engagement, as evidenced by our 9 first-place awards in local parades. Owner Jet Renkert brings over 30 years of experience in working with children and holds a teaching degree in Physical Education/Elementary Teaching from the University of Washington.
