Dr 420 Hawaii is a medical marijuana certification team in Hawaii. Since 2003, we have proudly provided marijuana certifications to qualifying patients in the state of Hawaii. Our team of licenced physicians evaluates the patient’s medical condition after an appointment has been made before granting them a medical marijuana certification. We have two Medical Doctors, one APRN, and an LCSW Care Coordinator, plus support staff, on our team. We have a highly trained, experienced, and quality system of care to meet your Certification needs. Though we are located in Hilo on the Big Island, we also travel to O’ahu, Maui, Molokai, and Kauai monthly to hold clinics for new and existing patients. Providing state-wide service with Aloha!
