Yvonne Hamm has been a certified GYROTONIC® instructor since 2007 and is certified on the Jumping/Stretching Board, Leg Extension Unit and GYROTONER®. She also has extensive experience and training in dance and creative movement.

Yvonne Hamm began at the Dance Teacher Training College in Hamburg, Germany. After graduating she got a degree and license in psychomotor training from the Motopaeden School in Dortmund, Germany. She made a leap of faith after that and decided to move to New York City to deepen her dance training.

Yvonne performed with Duden Dance Company in England and NYC.

Ms. Hamm received her Master of Arts in Dance from American University, Washington DC. She then founded and is the Director of Dance Discovery, a children’s dance school in Washington DC.

Yvonne was introduced to GYROTONIC® exercise through a dance friend, and it resonated with her. Shortly afterwards, she became certified and has constantly worked to develop her skills. Because of her dance background and extensive work with children, Yvonne can easily relate to clients of all ages, and is able to tailor training programs to individual needs and abilities. 

Her passion for GYROTONIC® exercise combines the love of dance and the energy that Gyrotonic creates. The ways it changes the body, the fluidity of the movements and the endless possibilities to use the machines make Gyrotonic continuously interesting for Yvonne to teach and for her clients to apply.
