Our Leaders
Director
Lee Bent has been working with children with Autism and other developmental challenges for over 25 years. With her background in psychology and her extensive experience in the field, Lee found her passion working directly with the children. She has worked with children as young as 2 ½ and up to 18 years of age in numerous settings (home, centre, community, school, day care and social groups. Lee has an innate sense for behaviour management and was quickly promoted to a Senior Therapist where she worked alongside a Clinician who nurtured her flair with ABA. After seven years in the field working with numerous children, on her colleagues encouragement, she decided to open a centre to utilize, nurture and expand her skill set and broaden her experience working with children with particular challenging behavioural needs. After much consideration, Endless PossABILITIES opened its doors in September 2008. Since then, Lee has groomed her clinical team to implement her strategies in teaching the children and reducing challenging behaviours to manageable levels. Her passion for what she does is evident, and her efforts are supported by the children’s gains.
Under the guidance of her then clinical supervisor, Lee participated in a successful supported inclusion pilot in a school for two years from 2005-2007. She had a full team supporting a child daily from 9:00-3:15 and teaching the full time EA how to prompt, motivate and redirect the child. Lee is quite aware of the challenges that exist in a classroom setting when support is insufficient especially when challenging behaviours interfere with a child’s ability to learn. This pilot resulted in great gains for that child both academically as well as socially. These strategies have long been used in Endless PossABILITIES’ classroom with great success! This is an area that Lee is passionate about, and continues to pursue and encourages collaboration and open communication with the schools. She knows with proper support, children with ASDs can do better in a school setting.
Lee is an avid advocate for children on the spectrum and supports the Autism Community in their quest for a fair and equitable program for children with ASDs. Lee has worked with families privately, as well as those under the old AIP and the OAP. She knows the importance of a true needs based program and how it results in greater gains. She has facilitated and attended meetings with MPPs, parent groups, town hall meetings, rallies, walkathons and the like, not only to raise awareness, but to show her support to the children she works with, their families and the community.
Lee’s goal is to create a safe and fun environment for the children we service, to teach independence, nurture self-esteem, and increase their learning. Her desire is to generalize the skills learned at Endless PossABILITIES, to all settings through collaboration, and consultation with everyone involved with the child. Accountability and transparency has always been a priority for Lee, and it continues to be so!
