The team

Meet the Board

In late 2017, the LDAA evolved from our original status as a grassroots registered charity to a mature organisation with a framework that reflects our long term vision. Our first Board was established in November 2017; we are proud to introduce you to the members below:


Sharon Whiteman, CEO

Sharon has worked in the field of health and wellness for almost 40 years. She was an Intensive Care Unit nurse for 20 years, and has run a business focussing on nutrition for a further 18 years.

Sharon has been involved with  the LDAA since its inception in 2009 and fulfilled the role of president 2013-2017.

She has 25 years experience leading teams of volunteers from all walks of life, who have appreciated her calm manner, commitment to staff development and engaging style. Despite being a recovering patient herself, Sharon has been a tireless campaigner of justice for patients of Lyme disease and Lyme-like illness. She’s an endless source of inspiration for her team.



Marie Huttley-Jackson, President

Marie works in a policy role in government in the area of industry innovation, and recently completed a Masters degree in Marketing.

Driven by generosity and compassion, Marie has been volunteering her skills to small charities for over 20 years. The LDAA welcomes the experience she’s gained through numerous leadership roles, and her insight from working for a large health charity in the areas of media, marketing and engagement.

Marie first joined the LDAA in 2014 as the mother of a child with Lyme-like illness. She credits the LDAA with helping her family through this difficult time, and is looking forward to providing others with that same support. We are pleased to announce that after appropriate treatment, Marie’s daughter is now in remission.


Jennifer Sherer, Vice-President

The LDAA has been fortunate to have had Jennifer fulfiling the role of Vice President since 2013. An  engineer who runs her own business, Jennifer is experienced at explaining complex concepts to a varied audience – which is why she does such a great job of leading our social media team!

Jennifer has a long-term interest in medical science and a passion for human rights. She is a recovering patient who gets a lot of satisfaction from empowering fellow patients with knowledge, and watching them regain control over their lives.


Tanya Kerr, Treasurer

Tanya is a degree-qualified accountant with her own business. She has over 15 years experience in commercial, cost and management accounting across a wide variety of industries.

Tanya balances her head for figures with a heart for the community – she has previously served as a volunteer treasurer for
K-9 Search and Rescue, and her children’s public school. Tanya is also a Justice of the Peace, who consistently supports small charities.

Tania is neither a patient nor a carer - she's a concerned member of the general community who contacted us after reading about the dreadful experiences of Australian patients and seeing the massive efforts of our small organisation to raise awareness.


Ann-Maree van Dalen, Secretary

Ann-Maree has worked in education for 27 years, primarily in her favoured area of special education. She has worked internationally as a teacher, teacher-in-charge of a Special Education Developmental Unit and an Assistant Director of an ABC Learning Centre.  A dedicated and active member of the community, Ann-Maree is also a kinship carer as part of Foster Care Queensland and has been a secretary and member of her children’s kindergarten committees.

Ann-Maree attributes the diagnosis and successful treatment of her daughter’s Lyme-like illness to the LDAA’s guidance. As a result, she has volunteered with us since 2014.

As a mother and special education teacher, Ann-Maree is committed to communication, organisation and teamwork; exactly what we need in a secretary.


Rebecca Vary, Board Member

Resilient and resourceful, Rebecca established an award-winning business while suffering from chronic, yet undiagnosed Lyme-like illness. She has utilised her networking skills to build strong relationships amongst the isolated Western Australian patient and scientific community.

Rebecca is a long term passionate and determined advocate for patients, who addressed the 2016 Senate committee on Lyme-like illness on behalf of the LDAA.

Rebecca has volunteered for the LDAA since 2013, and we’ve benefited from her consistent and thoughtful contributions. After seeking appropriate treatment in Australia and overseas, she is now in remission.


Catherine Stace, Board Member

Catherine has more than 30 years of experience working in the corporate and not-for-profit sectors. Her expertise is in developing change strategies and leading business growth across reputation, revenue and relationships.

As a previous CEO of the Cure Brain Cancer Foundation, Catherine’s vision, strategies and leadership resulted in transformative change. This included a global collaboration to create a personalised medicine platform, being crowned the 2016 Australian Charity of the Year at the Australian Business Awards, and ranking 25th  at the Australian Financial Review Innovation Awards.

Catherine stepped down from the Foundation in 2016 due to complications with Lyme-like illness.

Perpetually driven, she has since joined the LDAA, and we are grateful to benefit from her extensive insight.


Anne Ryan, Board Member

Anne has a background in policy, research and strategy, honed while employed at Canberra Airport.

She also has political experience, having been a Councillor and the Deputy Shire President of Busseltown Council for five years.

Anne developed Lyme-like illness in early 2016. Her tenacious spirit has lead her to retrain for an IT qualification, develop an interest in medical research, and join the LDAA team. We look forward to benefiting from her varied knowledge.
