Medcorp International History
Dave Berberian founded Medcorp International in 1998 after four decades spent in the pharmaceutical industry working at large corporations in the U.S. and abroad. Dave’s vast knowledge of marketing and sales of medical products, especially contact lenses, coupled with relationships cultivated during his corporate career, led to the establishment of Medcorp International.
A lasting friendship with David Cantor of Cantor Barnard Ltd. was forged during his 7 years building the Allergan U.K division. This connection allowed Medcorp to serve as a major U.S. distributor of prosthetic lenses for Cantor Barnard. It is with great pride that sisters Anne Berberian and Silva Karageozian took the helm at Medcorp, since Dave’s sudden passing in 2025. Dave’s legacy continues to this day.
