Meet 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 and educational programming, their collaboration facilitates the development of high quality program that reflects their commitment to:
evidence-based and student-centred service,
respect for neurodiversity,
operating from the midpoint of behaviour science and mental health,
and, balance and trauma-informed service delivery across therapeutic and educational streams.
