About Diamond Pharmacy
Diamond is the nations largest correctional pharmacy provider and Pennsylvanias largest independently owned Long Term Care pharmacy.
Diamond's success began in 1970 when Gilbert and Joan Zilner, both pharmacists, purchased a retail pharmacy located in downtown Indiana, Pennsylvania. Mark Zilner joined the business in 1991 and provided new perspective and energy. Mark has helped 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, currently operating a 135,000 square foot state-of-the-art institutional pharmacy, IV infusion facility, two retail pharmacies, and a medical supply facility. Combining the values of a family owned business with cutting edge technology has made Diamond a company in which customers will find a mixture of the latest industry technology in unison with old-fashioned hard work.
In 2001, Diamond surpassed all competition to become the nations 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 individuals and facilities.
Diamond is accredited by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), whose criteria set the standards on quality patient care. Diamond's Medical Supply and Infusion Division are also accredited by JCAHO.
