About Our Teachers 

Mary J Poppins 

Sativa Science Club Founder

Mary began to focus on her interest of herbal medicine early in 2004.  What started as a casual hobby quickly became a full time obsession and before long she found herself studying under some of the most respected plant people in the country.  After completing formal herbal training and 2 years of in depth clinical apprenticeship she began to feel the need to specialize her path.  Adding cannabis to her practice was, of course, a natural progression.  She packed her bags in the fall of 2010 and headed for the Emerald Triangle where she spent her days on a family owned medical farm and her free hours studying cannabis as a powerful healing tool.  

By the time she made it back to Portland she had made up her mind that clinical herbalism was not the path for her.  So she went back to college, preparing herself for the inevitability of legalization.  An Associates in Community Health Education, Bachelors in Sustainable Business, and several Project Management certificates later she is a social entrepreneur with her own triple bottom line: People, Plants, and Party's.

Emma Chasen 

Director of Education, Farma

Emma Chasen has a mission to educate people on the science behind Cannabis so that they may take charge of their own healing.  After graduating from Brown University in 2014 with a degree in Medicinal Plant Research, Emma went on to coordinate Clinical Oncology trials with the Brown University Oncology Research Group.  When her supervisor refused a Cannabis trial in favor of another expensive pharmaceutical drug, Emma quit and headed across the country to Portland, OR.  

She found her way to Farma, the popular Portland dispensary that takes a more scientific approach to Cannabis; rejecting the Indica/Sativa binary and instead focusing on chemotypes to determine effect.  There she has been able to study the plant and help patients reframe their relationship with Cannabis as medicine.  She is now the Director of Education at Farma and helps to train staff on Cannabis science, research and empathetic patient care.  She seeks to spread her educational program through teaching, writing and consulting.

Eric Wendt
