Columbia Care is a patient-centered healthcare company setting the standard-of-care for medical marijuana. We have four key commitments:


We consistently provide the highest quality medical products by growing our plants on our own farms and cultivation centers to provide natural and carefully controlled micro-climates. We proactively educate patients on the safe use of medical marijuana.

Scientific Leadership.

We partner with renowned academic and medical organizations to drive new research and have the nation’s leading body of clinical data through our patient registry. It contains data from thousands of patients suffering from over 20 different disease states.

Excellence & Expertise.

We are the first and largest medical marijuana healthcare company to operate both dispensaries and cultivation centers across the United States. We have worked with many thousands of patients in over 700,000 interactions to-date.

Compassion & Care.

Our patients are our number one priority. We offer subsidies to lower the cost for those who qualify, including senior citizens, military veterans, the terminally ill and those in financial need. In addition, we donate up to 15% of net income to local charitable organizations and programs.


When I first met the Columbia Care leadership team I was highly impressed by their professionalism and how seriously they take the business… they are making an important contribution to happier and healthier lives.
