Wow Vision Therapy

Residency in Vision Rehabilitation, with Emphasis in Vision Therapy and Vision Rehabilitation, and Pediatric Optometry 

Those who complete their 1-year private practice residency at Wow Vision Therapy will experience personal satisfaction and professional confidence gained through advanced skills in one of optometry’s greatest specialties – developmental vision, vision therapy (VT), and neuro-optometric vision rehabilitation. Our residents will learn the best practices in providing vision therapy, staff training, and practice management tools for building a successful VT practice.

Wow Vision Therapy currently has two clinical locations. The first is located in St. Joseph, Michigan, which is nestled on the shores of beautiful Lake Michigan. Our second office is located in Grand Rapids, MI, which is the second-largest city in Michigan.


The resident will experience a unique opportunity to develop proficiency in developmental vision, binocular vision, rehabilitative vision therapy, and pediatrics.  Merging principles in cognitive visual neuroscience with human factors in private practice, the post-graduate clinician will acquire the skills needed to excel in education, research, and patient care.

Under the direction of Dr. Dan Fortenbacher, our residents will immerse themselves in a practice that is dedicated to the diagnosis and treatment of patients with problems associated with binocular vision, accommodation, oculomotor function, visual information processing, visual-sensory, and motor integration.
