TSA was established by volunteers from the TSC community and those with a personal connection to TSC remain closely involved with TSA. We acknowledge and thank our previous leaders including Lynn Wilson and Sue Pinkerton.

Management Committee
The Tuberous Sclerosis Australia Committee is a dedicated set of volunteers. Many have a personal connection to TSC including having TSC themselves or a family member with TSC.

Debbie and her husband Anthony have two beautiful daughters, Alana and Sophie. Alana was diagnosed with Tuberous Sclerosis Complex at seven months old and has autism, a developmental delay and epilepsy.
