Heidi Prieur, FNP-C, ENP-C
Telehealth Specialist
Heidi Prieur is Board Certified as both a Family Nurse Practitioner and Emergency Nurse Practitioner, with more than 20 years of experience in Emergency Medicine and Urgent Care. She earned her Bachelor of Science in Nursing from Salem State University and her Master’s degree from Regis College, graduating with high honors.
Heidi is a registered medical provider with the Massachusetts Cannabis Control Commission and has been conducting medical marijuana evaluations for over a decade. She is an experienced cannabis clinician, a member of the Society of Cannabis Clinicians, and certified in Basic Cannabinoid Medicine through the Society of Cannabis Clinicians. Her approach to cannabinoid therapy is evidence-based, patient-centered, and grounded in clinical experience.

She works collaboratively with patients to develop individualized care plans to help restore balance to the body’s endocannabinoid system (ECS) to support overall wellness and improved quality of life.
Outside of her professional work, Heidi enjoys spending time with her husband and four children, listening to music, reading, and working in her garden.
