Sherri Mack, RN, BSN, and Elisabeth Mack, RN, BSN, MBA, are pioneering nurse leaders who co-founded Holistic Caring® & The Green Nurse® in 2015—an innovative national platform delivering cannabis education, clinical guidance, and patient-centered care. Both discovered the healing power of cannabis through personal health crises: Sherri reclaimed her health using plant medicine, inspiring thousands through her award-winning Green Nurse Podcast and integrative healing work. Elisabeth turned to cannabis after a debilitating bicycle accident and transitioned from a successful career as a nurse insurance executive to become a leading educator in cannabinoid therapeutics. Her nurse training manual evolved into a published book and a suite of accredited programs for healthcare professionals. Together, they’ve built a comprehensive ecosystem that modernizes cannabis care from education to clinical services—and now, to wellness products. Their acquisition of Bloom Hemp CBD brought their vision full circle: a women- and nurse-owned CBD emporium dedicated to safety, quality, and holistic healing. Bloom offers organic, doctor- and nurse-formulated hemp products inspired by Ayurvedic principles, along with personalized nurse-led services including a free nurse hotline and individualized cannabinoid care plans.

As longtime attendees of Patients Out of Time, we hold deep respect for the unique space this organization creates. It’s more than just a conference—it’s a gathering of minds and hearts devoted to the medical cannabis movement. Every time we attend, we’re struck by the depth of the clinical content, the integrity of the research shared, and the opportunity to connect with pioneers in cannabis and hemp science. This organization stands out for its unwavering commitment to the medical needs of all patients—especially those who are too often forgotten or left behind. In a rapidly changing industry, Patients Out of Time reminds us why we do this work: to ensure that compassionate, evidence-based care remains at the heart of cannabis medicine.
