Rob Mermin studied under Mime under Marcel Marceau and in addition to being a Mime is a director, lecturer, author, clown, magician, and raconteur.  He has Parkinson's Disease and used his training as a mime to develop The Parkinson’s Pantomime Project (PD Mime).

PD Mime explores methods of training in specific motor skills adapted from the techniques of pantomime and circus to modify or alleviate symptoms of idiopathic PD. One goal of the PD Mime classes is to trigger the Paradoxical Kinesia Impulse (PKI) as a movement management strategy.
