Our Directors

Alley and Billy started MM in 2011 with a vision of  a hybrid program bridging the gap between therapy and education; to create a program that changed the landscape of available services for kids with diverse needs in Ontario. 

With Billy at the head of business relations, and Alley at the head of clinical programming and outreach, their collaboration facilitates the development of high quality program that reflects their commitment to evidence-based service delivery that supports child development at every stage of development.
