Joanna Duyvenvoorde, S.A.C. Dip -Trustee


Joanna is a Lincolnshire, England native with a 16-year career in personal banking.  She left the industry in 2008 to partner with her brother in a joint business venture.  Joanna holds a Level 4 certification (Distinction) in Drug, Solvent & Alcohol Abuse Counselling and also graduated from the Society for Companion Animal Studies (SCAS) as a qualified Pet Bereavement Counsellor for the UK animal charity, The Blue Cross.

In October 2013, Joanna began TSM using naltrexone.  In an effort to help others, she set up C3 Foundation Europe in April 2014 to help raise awareness of TSM.  Under Joanna’s guidance, C3 Foundation Europe has been instrumental in aiding with information and resources both before and after the approval of Nalmefene (Selincro) as a medical treatment for AUD in the EU member states.   C3 Foundation Europe also provides support for people worldwide, in countries as far away as Australia, New Zealand, Thailand, America and Canada.

In her spare time, Joanna is a keen cyclist and animal enthusiast.
