About District Cannabis

District Cannabis Began with a chance Meeting between its founders Edward Weidenfeld and andras krischner

Ed comes from a background of administrative law and has served as counsel to pharmaceutical manufacturing companies, as well as on high-level boards and commissions under six presidential administrations. After being diagnosed with Parkinson’s Disease, Ed discovered that cannabis was instrumental in improving his quality of life with a degenerative disease and made it his mission to grow the cleanest and most effective medicine possible.

Andras comes to the medical cannabis industry from a different angle; after completing his bachelors in Sustainable Agriculture, Andras went on to found an 80-acre organic vegetable farm in Vermont, where he was tasked with amending and rehabilitating the fallow hay fields into a profitable and efficient farm, well-drilling, installation of irrigation and septic systems, and the construction of two (2) x 1,500 square foot greenhouses. After several years of farming, Andras relocated to California to work with and train other experienced cannabis cultivators. Andras built a warehouse cultivation facility that supplied medical cannabis collectives and dispensaries with what was widely recognized as some of the finest medical grade cannabis in the Bay Area.

The combined passions of public policy, public health, and sustainable production led Ed and Andras to open the District of Columbia’s premiere medical cannabis cultivation facility, with a strong company ethos of providing the highest standard products to local medical patients, and treating the plant with integrity and respect. The staff at Phyto is comprised of individuals with backgrounds in horticulture, genetics, culinary, construction, retail and other careers that lend their experience to cannabis cultivation. The combined knowledge of our seasoned team allows us to create a truly world class medicinal product, designed to fit into a patient’s everyday life.
