Farmacy partners

Farmacy Partners is a physician-owned and operated retail experience based in South Central, Pennsylvania. For years as an orthopedic surgeon, Dr. Steve Groff was confined to treating patients with traditional pain and recovery methods. As plant-based wellness solutions have become more prominent and accessible, Dr. Groff became convicted to educate his community and future generation of patients. This passion spawned the creation of Farmacy Partners which evolved into a voice of reason in an otherwise confusing industry. Our Farmacy Partners products are all formulated, compounded and fulfilled in South Central Pennsylvania, and are part of the vertically integrated hemp initiative that is Groff North America. The Farmacy Partners difference lies in its physician-owned story, local priorities, and global proficiency.
