Dr. Scott Weaver and his wife Julie started vision therapy in Dr. Weaver's practice in their new building in Dallastown, PA, in 1990, to provide a desperately needed service in York County. They specialized in treating children with Vision Related Learning Problems.

In 1992, Dr. Christa Roser joined the practice and expanded the scope of care to include the treatment of strabismus, and amblyopia (eye turns/double vision, and lazy eye). At this time, Vision Therapy Associates of York was founded as a separate practice, and was one of only 13 practices in the country which was dedicated solely to vision therapy.

In 1993, the practice expanded into the area of vision rehabilitation of brain injured patients, when Dr. Roser was asked to consult at The Rehab Hospital. Dr. Robert Hollenbach joined the practice in 2001 to help cover the growing practice's needs with his love of helping children and those with special needs.
