Trina Hazzah was born and raised in Washington DC. She attended Tuskegee University School of Veterinary Medicine where she earned her Doctor of Veterinary Medicine in 2006. She completed her small animal internship at Red Bank Veterinary Hospital in New Jersey and a 3-year residency in medical oncology at the Veterinary Oncology and Hematology Center, in Connecticut. She has also completed the requirements to be a Certified Veterinary Chinese Herbalist from the Chi Institute of Traditional Chinese Veterinary Medicine.

Dr. Hazzah developed an interest in cannabis medicine during her quest for finding effective integrative approaches for veterinary cancer patients. She has spent the last half a decade reading through available literature, attending multiple cannabis conferences and symposiums, while also learning from cannabis physicians.  She has since given numerous lectures to veterinarians educating them on the topic of cannabis medicine, published a peer-reviewed Cannabis in Veterinary Medicine journal article, co-authored multiple cannabis-related textbooks, and is the president and co-founder of the Veterinary Cannabis Society, which is the first US-based non-profit, 501(c)(3) organization building awareness of cannabis as medicine for pets. After almost 15 years of practicing medical oncology, she switched her focus to cannabis medicine full time and started a cannabis consulting service, called Green Nile, Inc.
