Director & Founder:

Leslie Vella, M.A., BCBA

Hello and thank you for visiting our website! My name is Leslie and I am a Board Certified Behaviour Analyst (BCBA®).  I have had the honour of working with children with autism and their families for over 21 years. I have worked in both the public and private sectors of autism services, as well as within the school board as an ABA Specialist.  My journey began at Trent University in Peterborough, Ontario where I received my Honours Degree in Psychology. In my fourth, year I took a ‘Behavioural Psychology’ course and it changed my life forever. Shortly after graduating, I was hired by a family to work with their son who had autism. I was so excited to be able to implement all my newly learned behavioural principles.  It was such an amazing and rewarding experience to be part of his team. A few years later, I received my Master’s Degree in Psychology with an emphasis in Applied Behaviour Analysis from the University of Nevada, Reno.  The knowledge and experiences I gained through my Master’s Degree further strengthened my love and dedication to this field. My journey continues at Reaching Beyond where I get to live my dream everyday!
