“I have always wanted to go into the healthcare industry because I love helping people. Vision impacts so many aspects of our daily lives and even small struggles in this area can be great stressors when completing everyday tasks. Helping patients accomplish their goals can greatly improve their self-esteem, academic efforts, occupational goals and overall quality of life. The excitement my patients express as they notice progress due to strides in our vision therapy program makes my job worthwhile.”

"I enjoy working with people and helping them grow. I like being able to share in the joy when a patient is able to do something that was previously impossible. Vision Therapy is also the only field I know of that lets me combine my experience with people on the Autism Spectrum, with my love of physics. The most rewarding part of my job is knowing I’ve made a difference in someone else’s life."

Our Founder 

Harry WachsThe Vision & Conceptual Development Center (VCDC) was founded as a private practice in 1996 by the late Harry Wachs. Previously, he had created a successful optometry practice in Pittsburgh, and reading centers in both Catholic University of America, and George Washington University. He designed the foremost home vision training kit that is used by many vision therapy offices today. His influence still persists through his published articles, and the books Thinking Goes to School and Visual/Spatial Portals to Thinking, Feeling and Movement. They are the foundation of Visuo-Cognitive Therapy that still evolves today through our office, other private optometric offices around the world, and as well as professional organizations like Profectum and ICDL.
