Our Board of Directors

The Board of Directors of the NHAA exists to directly support the membership and implement the policy and aims of the Association.

The support of the Board requires considerable decision making, strategy direction and ensuring of outcomes in many different areas from education, seminars and conferences, media and marketing, membership issues, to governance, law and ethics, government liaison (at the state, federal and even international level) and industry cooperation.

Each Board member is an elected representative of the membership and works in a voluntary capacity. Elections take place at the Annual General Meeting (AGM) of the Association and all Full members of the NHAA are eligible to vote. To find out more about how the Board of Directors works please read here.

Natalie Cook


I have previously served on the NHAA board from 2013-2019 completing the maximum term at that time. I contributed initially leading the marketing and communications sub committee, then Vice President then ultimately President from 2015-2019. I am proud of many of my achievements whilst on the board, and highlights include; activating a focus on communications to members of parliament and the media – one of which saw me representing the NHAA being interviewed on The Project, changing the name from National Herbalists Association of Australia to the Naturopaths and Herbalists Association of Australia to better reflect our membership, joining the World Naturopathic Federation as a foundation member, representing Australia on the WNF Executive as Treasurer and setting the associations focus on celebrating our 100 year anniversary.

My background in the corporate, small business and academic worlds, provides me with the unique skill set, perspective and experience that I bring to this role including: lecturing and curriculum development for the BHSc Naturopathy, Program Management, experience in the corporate and not-for-profit sector across a variety of management roles and of course private practice as a naturopath. I am currently a member of the Jacka Foundation for Natural Therapies and am employed as Director of Innovation, Industry & Employability (Health & Education) at Torrens University Australia. I feel I have more to offer the NHAA serving an additional term on the board and would appreciate the opportunity.

Sophia Gerontakos


Sophia is a Blue Mountains-based naturopath, massage therapist and researcher. Sophia wears many different professional and personal hats always endeavouring to balance her love of clinical care along with that of research. Amongst these hats, Sophia consults with and facilitates groups for naturopathic practitioners incorporating group consultations into their clinical practice. She also works as a massage therapist/health promotion worker at a local women’s health centre, and co-ordinates an MS cohort study at the Sydney Adventist Hospital. Alongside these roles Sophia is a PhD candidate with the National Centre for Naturopathic Medicine where she has explored healthcare experiences of women with endometriosis, and trialled a 12-week program of naturopathic group consultations for women and gender-diverse folk with endometriosis.

The aim of this research is to help meet unmet healthcare needs of those with endometriosis and to explore a new model of delivering naturopathic medicine to address issues of access and integration. Sophia believes naturopathy is an important yet under-utilised component of Australian healthcare, an essential and collaborative care-type to improve patient outcomes. Her desire is to see the advancement of naturopathic medicine where it is accessible to all Australians, and to advance naturopathic education with the incorporation of innovative models of delivering naturopathic care to improve access, and integration into the healthcare landscape in sustainable and fulfilling ways for naturopathic practitioners. When the professional hats are off Sophia simply wants to be in nature – her greatest inspiration, eat good food (with good people) and enjoy slow moments.

Board Member Advisory Committee

One of the major responsibilities of the BMAC relates to recruitment to the Board. It is the responsibility of NHAA members to elect the Board. However as the Board’s tasks change and become ever more complex, the NHAA also needs to ensure that procedures are in place that will enable it to access members with the right mix of experience, skills and interests for Board positions, both to fill interim vacancies and to stand for election at AGMs.
