Mission, Vision, Values

To foster the spirit of global community that cannabis enthusiasts, patients, and consumers share, by curating and shaping elevated experiences.

  • To cultivate a cannabis-positive world through discovery, community involvement,
    and outstanding products.
  • To honor our commitment to our patients by giving genuine advice, building rapport, and learning what is best for each individual who walks through our doors.
  • To provide unrivaled products by continually refining and perfecting our menu, and by never allowing anything less than the best to be sold on our shelves.
  • To support local culture by representing and dispensing the greatest of what Ann Arbor and Michigan have to offer.

Our History

In 2016, we opened Greenstone, inspired by the idea of a provisioning center that was more than a location, name or storefront.We envisioned a place full of premium products—a domain pioneered by those who believe that high quality medicine should be available to any patient from any background or walk of life.

Armed with compassionate expertise, our founders and a group of brilliant budtenders broke ground in the heart of Ann Arbor and established something completely different.  We march toward the future, but our soul stays true to the art of excellent cannabis, and the transformative power it has on people’s lives.
