Our Story

The Plater Family is actively seeking Licensure from the Maryland Medical Cannabis Commission to cultivate Medical Cannabis.

 Our African-American family was born and raised in Calvert County, Maryland.  We have deep ties to the county that go back several generations.  We own businesses in the county that have employed over 100 individuals.  The Plater family is once again interested in investing in the community by expanding our role as business leaders in Calvert County, by opening a Cannabis Cultivation Center.

The Platers come from a long line of care givers, many of us working in the healthcare industry.  We were initially hesitant to be involved in the medical cannabis industry, however, with immediate members of our family receiving relief of chronic pain by using medical cannabis, we have decided to apply for one of the available cannabis cultivation licenses from the Maryland Medical Cannabis Commission.

Our mission is to bring holistic relief to adults who suffer from the debilitating effects of epilepsy, cancer, MS and other end of life issues.

We bring to the table a wealth of medical experience and 100% diversity.
