Sandra Dieffenthaller

Sandra Dieffenthaller has been an active and committed member of Soroptimist International for over thirty-five years and is widely regarded as a trusted resource within the organisation. She has held nearly every club office and has played a central role in training, mentoring, and developing members, with a particular ability to identify potential and encourage leadership.

A former councillor of the Federation of Great Britain and Ireland and twice president of the National Association of Trinidad and Tobago, Sandra has led the development and chartering of several Soroptimist clubs and contributed to membership growth across the region. Her service extended to the Caribbean Network, where she served as membership officer, supported the revival of SI Providenciales, and assisted with the federation conference in Barbados. In 2007, she was honoured with the Caribbean Soroptimist Award.

At federation level, Sandra served as membership director on the Federation Management Board from 2004 to 2007, delivering training across the United Kingdom, Nigeria, Cameroon, and South Africa. A regular attendee at federation conferences and international conventions since 1997, she has presented at conferences across the UK and represented her country at Soroptimist International quadrennial conventions in Scotland, Finland, and Australia.

Beyond Soroptimism, Sandra taught Science for twenty years at a leading boys’ college, and remained a much sought-after private Biology tutor for another twenty years. She served as chairman of the Corinth Secondary School Board, and as chairman and manager of the Soroptimist Home for the Elderly for fourteen years. She has also served on the Mental Health Committee of the South West Regional Health Authority and remained actively involved in community initiatives for several years.

Sandra lives in Trinidad and Tobago with her husband, Michael, and has one daughter, Simone, a son, Tyson, and two granddaughters, Samantha and Sydney. She continues to support the development of others through service and mentorship. She enjoys reading, cooking, travelling, and entertaining family and friends.
