Diamond Pharmacy Long Term Care Services


Pennsylvania’s Largest Independently Owned LTC Pharmacy.

In 1970, Gilbert and Joan Zilner, both pharmacists, purchased a retail pharmacy located in downtown Indiana, Pennsylvania. 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 our 135,000 square foot state-of-the-art institutional pharmacy, we operate additional satellite pharmacies in Ohio and Eastern Pennsylvania, two retail pharmacies, and a medical supply division. 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. We offer our customers the advantages of a large company with the service and approach of a family owned, home-town pharmacy.

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