Little Leaves is an organization of professionals who are passionate about working with children.
Our program is supervised by master’s and doctoral level Board Certified Behavior Analysts (BCBAs) and delivered by highly-trained therapists. We believe that our children’s families and caregivers are integral members of the treatment team and we treat them that way.
Little Leaves knows that providing the highest quality services to your child requires a team effort, and that is how we work. Within Little Leaves, we have created a model for our professionals to collaborate on treatment approaches, share best practices, and continuously learn from each other. Your child will be supported not just by his or her immediate team, but also by the decades of experience and expertise of all of our clinicians, many of whom have studied and trained in the finest ABA programs in the world.
