Dion Ma
Clinical Supervisor – Board Certified Behavior Analyst (BCBA)
Master of Science in Applied Behavior Analysis & Autism
Master of Social Science in Youth Counselling
Bachelor of Art in Psychology
Dion was trained as a behavioral therapist and has been working in the field for over 10 years. She sees the importance in helping individuals with special needs find enjoyment in the company of friends and social interaction. With that comes the task of teaching them ways to interact, and spontaneity in language they need in order to communicate.
Her busy schedule includes training therapists, designing programs and holding professional workshops. Before working at Ascend, Dion has worked with clients from a range of skill levels and age groups, in both mainstream and special schools, and in vocational training. To consolidate all of her experiences, she has obtained the certification for BCBA.
When she is not being ASCEND’s prized problem-shooter, she likes to tend to her herb garden and go to the movies.
