Sarah Halweil, R.N.

Sarah Halweil has been a registered nurse for over 20 years. Early in her career, she specialized in labor and delivery and later developed expertise in cannabis as medicine.

Since then, she has helped hundreds of patients with many conditions and challenges, including pain and opioid reduction.
She has provided cannabis guidance during hospice care
and as an adjunct to cancer treatment. 


Sarah was the clinical coordinator for a complementary therapy program at Southampton Hospital in New York. Her team used techniques including Reiki, yoga, and essential oil therapy to help patients cope with pain and exhaustion to experience better overall health and well-being. 

For people interested in using cannabis as medicine,

there are general guidelines, but many benefit from personal fine-tuning. Others have a few questions and need direction in navigating the burgeoning  field of cannabis. 


Nurse Sarah loves helping to find the best, most suitable regimen and providing medical feedback for her patients.
