Our Story
Riverdale Flip and Tumble Inc. was founded in 2017 in the heart of Greek Town, Danforth by Owner and Director Sibylle Mueller-Ritter, a former elite-level gymnast and coach with over 35 years of experience.
Dedicated to fostering health and skill development, we offer a fun, supportive, and engaging environment for children and youth. Our gymnastics-based programs are carefully designed for kids 6 months and up through their teen years, with each class tailored to suit the developmental needs of each age group.
With low student-to-instructor ratios and a focus on quality instruction, we ensure every child receives personalized attention. Our programs help young participants build strength, flexibility, coordination, and endurance—while also enhancing their confidence and self-esteem.
This facility (435-437 Danforth Ave.) serves as our recreational gymnastics studio; it features a 40-foot long trampoline called a Tumbl Trak, double tumbling floors, large fitness wheel trampoline, a hanging station with a trapeze, rings, and aerial hoop, a foam pit and more!
We specialize in Parent/Child classes, recreational programs, and advanced and pre-competitive training. We offer afterschool gymnastics training, weekend classes, PA Day Camps, Winter/Summer Camps and special events including Gymnastics Sleepovers, Holiday/Seasonal Parties and Term Showcases. We also host birthday parties!
Reach us by email anytime, we are always happy to help!

It helps develop physical abilities such as strength, flexibility, balance, and coordination, while also enhancing cognitive growth, confidence, discipline, and social skills.

My daughter has attended group classes, camp, had her birthday and currently has private lessons with the lovely and talented Ekin. This is a beautiful place for any gymnastic enthusiast to learn and play. My daughter has always had such a great time and wants to keep coming back. Shahla and Sibylle are the instructors/owners we have had the pleasure of interacting with over the last year and a half, and I can say with full confidence that they run the place with professionalism and creativity. Looking forward to many more years at flip & tumble.

RF&T is a really awesome place! Our daughter started going with my husband when she was a toddler and now, at not even age 5, she has already moved into a more advanced gymnastics class than the one she was in before - they really care to help the kids progress and be interested in what they’re doing.

I enrolled my daughter for the summer program in august to try it out and excited to say that she will be continuing in the next term of classes! The teachers [Sibylle and Tori] are super fun and energizing while engaging the children with safe practices :) I love the structure of the class and at the end of every class they blow up a bouncy castle for the kids 10/10 experience and highly recommend it for any parent wanting to get their foot in the door for their kids! Also the [Head Coach Tori] is a sweetheart!

Both my kids aged 5.5 and 3 have been attending Riverdale Flip & Tumble since the age of 2 and we love them. I started them each in the Parent n’ Tot class, and I personally enjoyed my time in the classes too!

We just finished our third session of classes with Coach Shahla and her team and we can't speak highly enough about the program. Our toddler has advanced through the parent/tot classes to the drop-off program and the care that the staff for the transition was incredibly reassuring.

We’ve been at flip and tumble since my kids were toddlers, and they’ve loved it at every stage. The staff are wonderful - accommodating, skilled and great with little kids. It’s been so good for their gross motor skills, but mostly they just have fun exploring their abilities in a safe space.
