Before discovering homeopathy, Susanna worked in Medical Research at Johns Hopkins Medical School and the University of Virginia Medical Schools in the USA. Her lifelong interest in spirituality however, led her to Scotland where she completed a postgraduate degree in Theology at St Andrews University as well as postgraduate work at Harvard Divinity School. Midway through her theological training she was introduced to homeopathy. After a great personal response to treatment she decided to pursue formal training in homeopathy with the National Center of Homeopathy (USA) and The College of Homeopathy in London in the 1980s.  Before migrating to NZ in 1991, she established a free children’s clinic in rural Kent and practiced at the South London Natural Health Centre in Clapham where her special interest in perinatal homeopathy began -- many of her clients were pregnant women and she worked closely with birth educators and midwives at that time.
In 1991 Susanna arrived in NZ, began teaching at Wellington College (WCOH), Hahnemann College in Auckland and Bay of Plenty College of Homeopathy (BOPCOH) in Tauranga.  That same year, she co founded a journal for the NZ homeopathic profession: Homeopathy NewZ and set up Selene Homeopathics— to supply quality homeopathic remedies to the profession and community.   She was an editor and co-director of these until 1994 and 1998 respectively.  In the 1990s Susanna continued to practice homeopathy and extend her tertiary education and management skills.
In 1991, Susanna registered with and joined the Executive of the NZ Institute of Classical Homeopathy and was appointed Dean of BOPCOH. She served on the NZICH Exec until 1996 and when the New Zealand Council of Homeopaths (NZCH) was formed in 1999, became an Exec, serving til 2006 and then again from 2009-2012.  She was awarded the Life Membership of the NZCH in 2015 .
In the early 90’s, Susanna established practices in Taupo and Wellington while teaching at WCOH and BOPCOH. From 1994-2012 she served on the NZQA Expert Panel on Homeopathy (which became the Homeopathy Profession Advisory Board in 2008); this group wrote the NZQA Unit Standards for homeopathy and developed the NZQA National Diploma and in 2008 reviewed these and established agreed training standards for the profession.  At BOPCOH she pioneered comprehensive distance education in homeopathy with College founder Greig Follas—initially via VHS, then DVD creating the platform for comprehensive online learning options.
In 1995, Susanna settled in Tauranga, became Principal of BOPCOH. She strongly fostered collegiality between NZ homeopaths and overseas colleagues presenting cases and papers at professional conferences in NZ, Australia and USA.
Susanna led the College to many significant milestones:accreditation with the NZQA; approval by the Ministry of Education (MOE) for student loans and allowances and approval of the College’s Diploma of Homeopathy in Animal Health by NZQA and MOE.
In 2004, Susanna was a guest tutor in homeopathy at Hong Kong University and later that year became owner and Principal of Sydney College of Homeopathic Medicine (SCHM).  From 2004-2008 Susanna was Principal and CEO of both BOPCOH and SCHM and managed the NSW registrations and approvals of the Sydney College during that time.  In 2008, Susanna’s duties re-focused to NZ when she was appointed Director of Operations NZ for Endeavour College of Natural Therapies which includes ongoing duties as Principal of BOPCOH.
From 2012-2020 Susanna took a 'sabbatical' from homeopathic teaching and management. During that time she co-owned and operated a successful VIP Toursim business based in the Port of Tauranga (NZ) catering to International cruise ship visitors.  She returned as Director of the College of Natural Health & Homeopathy (CNHH) in 2021 to help steer the College in its next chapter of growth.
Susanna’s vision for the profession has been and remains, “to have the highest level of homeopathic treatment
