Leading the Future of Cannabis Education for Health Professionals
Our mission & our work
Holistic Caring® & The Green Nurse® was founded with a simple belief: every patient deserves access to a healthcare professional who understands cannabinoid therapeutics.
Since 2016, Elisabeth Mack, MBA, BSN, RN and Sherri Mack, BSN, RN have been at the forefront of cannabis nursing, patient advocacy, curriculum development, and professional healthcare education. Together, they have dedicated their careers to bridging the gap between conventional healthcare and cannabinoid therapeutics through evidence-based education, clinical mentorship, and patient-centered care.
Over the past decade, they have personally cared for more than 6,000 patients and trained more than 500 healthcare professionals, primarily nurses, in the safe and effective use of cannabis and hemp therapeutics.
Today, their primary mission is educating, training, mentoring, and supporting healthcare professionals who want to confidently integrate cannabis medicine into clinical practice.
