Mark (former member of the British national team and assistant coach to the US Junior Olympic national team... thank you very much) and Donna (old... sorry, make that, former, Pennridge gymnast) wanted their gym to be different.First of all it has a unique name that reflects the energy of the kids it attracts (BOING!) It is bright and colorful. Classes are well planned out and fast paced (as little sitting around as possible.) Finally, Boing is small enough to keep its friendly family run atmosphere but large enough to offer kids a real gymnastics experience.
