WELCOME TO TUMBLE DOCTOR

We Are All Humans; We Are All Subjected to Laws of Gravity, Friction, Air Resistance, Inertia, Tension, Etc. These External Constants Dictate the Way We Live and The Way We Tumble.

Inner Drive Is the Dominating Variable Distinguishing A Good Athlete from A Great One.

about COACH ALVIN

❝ Do or do not.
there is no try. ❞

– Yoda, Star wars Episode V: The Empire Strikes Back

My gymnastics career was propagated by a zealous father who strongly believed that he could teach his three-year-old son a back handspring.

My father tied a belt around my waist and told me to try and throw myself backward. My mother told me that she watched as her ‘baby boy’ proceeded to jump back and land on his neck.

My father told me to try again, but my mom said, “No! He needs a professional to help him so he doesn’t end up in a wheelchair.”Thee next day, I enrolled in a gymnastics class.

I trained as a competitive gymnast for 10 years. I graduated college with a Microbiology and Molecular Genetics degree from Michigan State University. I matriculated into medical school for a year, but I decided to drop out after the first year, much to my parents’ chagrin.

After coaching gymnastics for a year, I enrolled in Michigan State University’s Broad School of Business, where I obtained an MBA in Finance.


I have had the opportunity to train athletes and teams worldwide. I strongly believe that my tenure as a competitive gymnast grants me a competitive advantage over most tumble coaches, who, like my father, have the best intentions but can lack the know-how to train and spot athletes.

He is just amazing! We have done 2 sessions with him so far virtual and the way he teaches and motivates is just incredible! He had me having fun along with my daughter. His personality is so fun! My daughter has been dealing with a mental block for a year now where she just lacks full confidence in herself. He is able to make her feel like the biggest super star and shows what her strengths are just by doing simple skills and drills. I can tell he has a way with athletes that others just don’t! I can’t wait to see him in person and see what he can get her to do!

My daughter is on her 5th year working with Alvin and his crew. They are unbelievable. He doesn't just push kids to tumble. He works with the whole child....physical, mental and emotional. All 3 are needed to be great athlete. He pushed my shy child from a level 1 to now a level 4/5. She trusts no one else and we follow him up and down the East Coast to work with him. He is family to us!!

Alvin and Jon are amazing with our athletes, and truly inspire them to work hard to reach goals. They are skilled, perceptive, and patient. It doesn’t matter if they are working on a forward roll or a full, they always encourage and motivate the girls in a positive way. We have seen immense improvements in our athletes and our scores with the coaching of Alvin and Jon and we are very grateful. Their positive attitudes and upbeat personalities are extremely infectious; it’s hard to have a bad day of tumbling with these two. We look forward to another fantastic season with them.
Michele Harris Alexander
The Tumble Doctor’s passion for producing quality athletes is remarkable. There is a definite focus on technique and hard work all while building the athlete’s confidence. My daughter has attended several clinics and always leaves with needed corrections and feedback but also restored energy and a renewed belief in herself. He has a true talent for inspiring young athletes to give it their all.
Kim Grillo
Alvin and his crew truly know how to bring out the best in anyone he coaches. Their positivity is infectious. My daughter loves anytime she goes to a tumble doctor clinic. I wish we could attend more. If you want the best of the best call Alvin.

We also completely believe in and trust his amazing approach to tumbling... his approach really makes the athletes beautiful, technically sound, and injury free tumblers! The entire staff is incredibly knowledgeable about tumbling, mental tumbling, science, sports nutrition, and the human body. He also has the best team of instructors around. We are life-long fans!
Jessica Wolfe Frankovic
Alvin is phenomenal! His dedication to excellence in every single athlete he encounters is not only inspiring but motivating! He is passionate about kids and success and has the perfect balance of competitiveness that pushes these athletes past their comfort zones! We were honored to have him at Encore Elite Allstars in Yakima, WA this past week!!!!! We will be bringing him back!!!!
Laura Rohanna
Alvin is extremely motivating and positive with athletes of all ages and levels. His energy is intoxicating but his knowledge on tumbling exceeds most! He teaches them to use their mental strength along with their physical strength. My daughter has loved working with him when level1 and continues to at level3. When the opportunity to train with him allows her to she will always be there.
