Farmacy Health

Farmacy Health is a physician-owned and operated retail experience based in South Central, Pennsylvania. As an orthopedic surgeon, Dr. Steve Groff treated patients with traditional pain and recovery methods. As plant-based wellness solutions grew more prominent and accessible, Dr. Groff became convicted to educate his community and future generation of patients on the benefits of cannabis. This passion spawned the creation of Farmacy Health and provided a voice of reason in an otherwise confusing industry. Farmacy Health 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 Health difference lies in its physician-owned story, local priorities, and global proficiency.
