Joanne is an Occupational Therapist with over 30 years of experience in the field. Born and raised in the United Kingdom, she graduated from St Loyes School Of Occupational Therapy in Exeter and worked for several years as an OT in England, including acute care and neuro-rehabilitation settings. After working on a summer camp for children and adults with disabilities, in Maine, Joanne moved to the US and worked in a rehabilitation and outpatient facility in Stamford CT. This outpatient role included working with adults and pediatrics as well as providing school-based services. She returned to England and took on a team leader role at an inpatient facility for children and young adults with acquired brain injury, which also included supporting the children in their return to school and the community. In 1998 Joanne returned to the US and started working at Norwalk Rehabilitation Services as a full-time school-based OT, soon becoming a team leader for 2 of the districts. During that time, she worked with team members to develop the role of OT as part of the programming in classrooms for children with ASD and later became part of the preschool assessment team. Joanne became assistant director of the school-based therapy program and along with the director of the program at the time continued to grow and develop the program, adding more districts, strengthening the school-based OT and PT staff members, providing staff training to the districts, and promoting school-based therapy in the community. She also was involved in the introduction of a web-based documentation and billing system for the program, which in addition to streamlining billing and payroll processes, also resulted in various data projects that could be shared with districts on efficiencies, caseload v workload and caseload trends. In 2013 Joanne became the Director of what is now Constellation School-Based Therapy, continuing to develop the program, providing ongoing training and support for the school-based therapists, strengthening relationships with school districts, and offering fieldwork experiences for OT and PT students. In 2017 school-based ABA services were added to the school-based program and then in 2021, Speech and Language Therapy was also added. More recently Constellation School-Based Therapy has been awarded contracts to provide related services in Rhode Island, Texas, Arizona, and Pennsylvania and looks to continue to grow school-based therapy programs both in CT and other states.
