Treasurer: Elizabeth Boyd

Growing up on a farm in Southwestern Ontario gave Elizabeth very strong ‘weed’ identification skills.  Most of her early jobs were in agriculture which exposed her to more Ontario plants, but as she started to explore the world of herbs she quickly discovered that most of the ‘weeds’ were actually very useful herbs!  From this background, Elizabeth prefers to use herbs in her practice that grow in Ontario and can be harvested fresh.  Elizabeth has been practicing herbal medicine from her home office in Burlington since graduating from the Institute of Traditional Medicine (ITM) in 2011.  

Elizabeth’s background also includes a degree in Chemical Engineering and Management from McMaster University and some time with TD Bank working as an Agriculture Account Analyst.  She uses her finance skills as the volunteer treasurer for the Burlington Women’s Basketball League and the bookkeeper for Clarkshome Farm.  Elizabeth is a Professional member of the Ontario Herbalists Association.
