Diamond Pharmacy Long-Term Care

Pennsylvania’s Largest Independently Owned Long-Term Care 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.

We’ve been filling prescriptions for long-term care clients since the early 1970s, when we were still just a little drug store on Philadelphia Street. In those days, our pharmacists would make the deliveries to the local facilities. Much has changed in the ensuing decades, but our focus on providing the very best service to personal care/assisted living communities, skilled nursing facilities, and their patients remains the same. We’re beyond proud to provide medications, medical supplies, and consulting services to over 250 facilities in four states. And we’re also proud of our annual Educational Conferences, an opportunity to be a resource for long-term care professionals through free continuing education courses.

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.
