We have proudly provided medical cannabis 329 card certifications for qualifying patients in the state of Hawai'i since 2003. Our team has assisted more than 4,000 patients to lawfully possess marijuana and cannabis products for medical use. Our main office is located in Hilo on the Big Island, and we travel to O'ahu, Maui, Molokai, and Kauai monthly to hold clinics for new and existing patients.

Our Team


Christopher Lawinski, MD - Medical Cannabis Physician

Dr. Lawinski graduated from the University of Pennsylvania School of Medicine in 2006 and from the University of Hawaii JABSOM Family Medicine Residency Program in 2009.  He has been practicing Integrative, Holistic and Functional Medicine on the Big Island since 2009 and has specialized in Cannabis Medicine since 2011, certifying patients across all the State of Hawaii’s major islands. The use of cannabis as a medicine is consistent with Dr. Lawinski’s guiding principals of Holistic, Integrative, and Functional Medicine in that he finds cannabis to be a superior alternative to many major classes of pharmaceuticals in the treatment of many patients' chronic and debilitating disease.  Certifying cannabis patients across all of Hawaii’s major islands allows Dr. Lawinski to contribute significantly towards the alleviation of chronic disease burden across the State, by giving patients access to a highly effective and legal alternative for their pain and suffering.


Matthew Brittain, LCSW - Care Coordinator

As a Licensed Clinical Social Worker, Matthew offers medical cannabis patients counseling to reduce the anxiety, social stigma, legal consequences, and interpersonal complications that patients often experience with this alternative medication. As a Forensic specialist in the cannabis field, Matthew has been called upon on a number of occasions to provide expert witness service for court-involved patients. Matthew has been an activist and advocate for medical marijuana and cannabis since the late 90s. He is proud to be a part of the Doctor420Hawaii team as Care Coordinator, ensuring that all patients get the care they deserve and safe access to legal medicinal marijuana.
