Our Office 

The Vision & Conceptual Development Center (VCDC) offers a wide array of vision therapies. After qualifying for therapy, each patient receives an individualized treatment plan, prescribed by their optometrist. Therapy is provided in 50 minute, one-on-one sessions with a vision therapist.


Our Experience 

The staff at VCDC brings a wide range of experience and knowledge to our practice. Both of our optometrists are Board Certified Fellows of the College of Optometrists in Vision Development (FCOVD), a specialty achieved by roughly one percent of optometrists in the country. In addition, they are both members of the Neuro-Optometric Rehabilitation Association. Dr. Zeller is an active participant within the College of Syntonic Optometry, Dr. Green is a certified DIR/Floortime professional. Between the two of them, they have over 20 years of experience. 

Our staff of vision therapists is equally impressive. Several are (or are becoming) Certified Optometric Vision Therapists (COVT). In addition to ocular therapy, several have backgrounds in neuro-rehabilitiation, primitive reflex remediation, Floortime, Lindamood-Bell programs, listening therapies, psychometric testing, vestibular processing, and syntonic phototherapy. Our vision therapists have almost 50 years of experience combined.


Our Technology

Our office uses a combination of traditional vision therapy tools as established by our founder, Dr. Harry Wachs, and the most cutting edge technology in the field.



The Visagraph III is a diagnostic tool used to determine reading ability. It maps eye movements while a patient silently reads an age appropriate passage. It compares the patient’s results against grade-level norms.   




The Visually Evoked Potential (VEP) is a diagnostic tool commonly used for patients with a Traumatic/Acquired Brain Injury (TBI/ABI). It uses EEG technology to measure the speed and strength of the visual signal sent from the eyes to the brain. 




The Visual Therapy System 4 (VTS4) uses various games and activities to improve specific ocular conditions. The 3D viewing glasses and video game controller, help gamify therapy, making it novel and stimulating for patients, while also providing objective measurements. 



The Sanet Vision Integrator (SVI) is an interactive TV display which provides visual stimuli that respond to physical touch. It utilizes multiple programs to improve eye-hand coordination, saccadic eye movements, and peripheral awareness, among other areas.
