Our Therapists

Our Therapists are the frontline staff and they play a key role in the success of our agency. They work with our families and children in one-on-one, group and school settings to carry out program goals as identified by our Supervisors and Consultants. All our Therapists have at least a bachelor degree; some of them have masters degree from local or overseas universities. They have gone through a minimum of 400 hours of training in the first year and receive intensive and ongoing training for about 200 hours every year thereafter by local and overseas experts in the field. Our Therapists are highly skilled and experienced, and receive extensive support and training to perform their duties with passion, expertise and confidence.   Training comes in numerous forms:
  • Pre-service Intensive Training and Orientation All new hires are required to complete 180 hours of pre-service orientation and training on implementing Applied Behavior Analysis with students with ASD. Training and orientation are in the form of lectures, case studies, role-play, case observations, and practical hands-on sessions closely monitored by our Consultants.
  • Monthly Training All Therapists are required to attend monthly training sessions to further their knowledge and enhance skills. On-the-job trainings are both didactic and practical, consisting of lectures, case studies, videos, evaluations, and role-play. Our Asst. Director, Mr. Toby Mountjoy provides the quarterly training at our office, while our director Dr. Ron Leaf from US Head Office visits Singapore annually to provide direct training to staff.
  • Weekly Supervision Our Therapists receive over 400 hours of induction training and 1:1 supervision by our Supervisors and Consultants in their first year on the job. Thereafter, staff continue to receive over 200 hours of supervision per year with weekly supervisions, regular clinics and team meetings specific to the child they are working with.

Evaluations are based on Therapists’ practical skills, programming skills, work attitude, communication skills, organization skills as well as professionalism and leadership skills.
