The Zilner Family

Zilner Family

Diamond Drug Stores, Indiana, PA

Diamond is the nation's largest correctional pharmacy provider and Pennsylvania's largest independently owned long-term pharmacy.

In 1970, Gilbert and Joan Zilner, both pharmacists, purchased a retail pharmacy located in downtown Indiana, Pa. Diamond Pharmacy's success began here and continued when their son, Mark Zilner, joined the business in 1991. Mark provided new perspective and energy, helping to improve, enhance, and add features that have led to an expansion of Diamond's services.

Due to the personalized service and cost effective pricing, Diamond has experienced tremendous growth in recent years. In addition to the 135,000-square-foot, state-of-the-art institutional pharmacy, they operate an IV infusion facility, two retail pharmacies, and a medical supply division. Diamond has opened a satellite pharmacy in Reading, Pa., in order to better service the eastern side of the state. Combining the values of a family-owned business with cutting-edge technology, Diamond has become a company which combines the latest in industry technology and leading experience with old-fashioned hard work. They offer customers the advantages of a large company with the service and approach of a family-owned, home-town pharmacy.

In 2001, Diamond surpassed all competition to become the nation's largest correctional pharmacy services provider. Continuing to lead the way, Diamond understands the responsibilities associated with satisfying the needs and exceeding the expectations of all customers and facilities.

Diamond is accredited by the Joint Commission, whose criteria set the standards on quality patient care. Diamond's Medical Supply and Infusion Division are also accredited by the Joint Commission.
