College Staff – Management

Susanna Shelton – Director

BA(USA), MDiv(UK), RCHom (Life Member), ADH

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. In 1991, she co-founded Homeopathy NewZ and Selene Homeopathics and was an editor and co-director of these until 1994 and 1998 respectively. In the 1990s Susanna continued to study homeopathy and tertiary teaching, course design, assessment and moderation; her focus on homeopathic education and management continued to expand.
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 NZCH was formed in 1999, became an Exec, serving til 2006 and then again from 2009-2012.
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 our 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 and organized many homeopathic seminars by overseas tutors: e.g. Misha Norland, Melissa Assilem, Miranda Castro(x2), Ian Watson (x2), Frans Vermeulen (x3); Alize Timmermann (x3); Alastair Gray (starting in 2000 then as a regular tutor since), Jose Mirelli, Nandita Shah, Diana Kopatsy (x3) Peter Tumminello (x2) and Ken D’Aran. She strongly fostered collegiality between NZ homeopaths and over the years engaged many of our finest homeopaths as tutors and visiting clinical tutors. Susanna has presented cases and papers at professional conferences in NZ, Australia and USA.
In 1998, Susanna completed Alize Timmermann’s post-graduate training at the Hahnemann Institute of the Netherlands and managed the BOPCOH’s registration as a Private Training Establishment with NZQA.
In 1999, Susanna led BOPCOH to become the first accredited provider of the NZQA Unit Standards in homeopathy and to achieve the College’s approval by the Ministry of Education for student loans and allowances. In 1999 and 2000 Susanna led the BOPCOH expansions of teaching venues to Auckland and Christchurch. She also managed the approval of the College’s Diploma of Homeopathy in Animal Health by NZQA and MOE in 2000.
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 2009-2012, Susanna was a representative to the NZCCHEP (NZ Consortium of Complementary Health Education Providers) and the NHC (Natural Health Council).
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 Tauranga catering to International clientele. She returns to 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 available to the greatest number of people (and animals); at a reasonable cost to the consumers and a professional level of remuneration to the practitioners”. She sees the College as a key player in this vision as it works with the wider community to make it happen.
Susanna is happily married to Karen. She is a proud co-parent of two successful and happy adult children and has been pleased by the love of many companion animals over the years. Main hobbies are sustainable food and wine, travel, wellness and following the All Blacks.

Susan Henricksen – Academic Manager

PGC(EdLM), GCHE, BHSc (Comp Med), Adv Dip Med Herb, Adv Dip Nat, Dip Hom

Education has always been a passion of Susan’s, especially to seek knowledge around medicine. Following a long career in a Medical Pathology Laboratory, Susan sought education in complementary medicine as a source of a more holistic approach to wellness. This resulted in Diplomas in Naturopathy, Western Medical Herbalism and Homeopathy and a Bachelor of Health Science. Practise gave way to education again and Susan started teaching at the Colleges she had trained at and also with Pharmacy staff as a Sales Rep with Naturopharm. Following six years at NZ College of Massage teaching Anatomy and Physiology, Pathophysiology, Research and managing the Auckland site, Susan has returned to her Homeopathy roots at CNHH after undertaking the role of Academic Manager. Susan draws on her knowledge and experience to support the students in their study in Homeopathy. There are also plans for a Masters in Education, the search for knowledge never ends!

College – Academic

Philippa (Pip) Andrews – Tutor (Human Homeopathy)

MSc, BSc, Dip Tchg, Dip Hom, RCHom

Hearing success stories from other Mums at our local playgroup had Pip trying homeopathic remedies for herself, and her young family. Having always been on the lookout for effective, safe alternatives to mainstream medicine, some early success in treating minor ailments with homeopathy clearly demonstrated its potential to Pip and ignited a curiosity which had to be followed.
She had her case taken by a local Homeopath which was a profoundly positive experience and the following year in 2014, she enrolled in the Diploma course at the College of Natural Health and Homeopathy in Auckland. These days, her bookshelf is bending under the strain. Previous tertiary qualifications include a Master’s in Environmental and Marine Science from Auckland University in 2000 and a Diploma in Teaching (Secondary, Science) from Waikato in 2006. Today, she is a fully registered member of the New Zealand Council of Homeopaths. Pip lives in a small coastal community North of Auckland with her partner, 2 children, some sheep, bees and chickens. She considers herself to be a lifelong learner.
