Quest Therapeutic Services, located in West Chester, PA (35 miles west of Philadelphia) provides exceptional pediatric therapy services to enhance the lives of children with disabilities in the Delaware Valley. Licensed physical and occupational therapists, speech & language pathologists, as well as special instructors, provide a full range of pediatric services to enable children with disabilities to develop to their fullest potential. Services are offered in a variety of settings to maximize results, including the home, school, community, as well as in our state-of-the-art therapy facility where we also offer Equine-Assisted Therapy or hippotherapy in our heated indoor arena. We offer services year round. 

Sandy McCloskey founded our program in 1996, when we served six children once a week. Since then, Quest Therapeutic Services has evolved into a full-time 501(c)(3) not-for-profit pediatric therapy program serving over 125 children per week, with a staff of experienced therapists, instructors, trainers and volunteers. Our goal is to continuously advance pediatric therapies through teaching, research, clinical partnerships and education throughout our community and our profession as a whole. We will continue with the dream that Sandy had for Quest and the children we serve.
