Lianna Marie is the founder of, a website which connects people affected by Parkinson’s disease from all over the world. Since 2005, the website and associated forum has had more than 1.5 million visitors and helped tens of thousands of people with Parkinson’s, their families, and their caregivers. She has also served as her mother’s caregiver and advocate for the past twenty years through the many stages of Parkinson’s.

Marie studied psychology and nursing in her university days but didn’t find her true calling until many years later. After living with Parkinson’s for about ten years, her mom realized there wasn't much information available on the disease that was being delivered by someone who had learned from living with it. Every book she found was written by a doctor, most of whom sounded like they were writing to other doctors--in other words, they wrote in language that wasn't always easy to understand. In response, Marie interviewed hundreds of people with Parkinson’s and researched ways to help them. She then compiled the information, along with her mom’s discoveries over the years, into her first book, Everything You Need to Know About Parkinson’s Disease (2005, revised edition 2015).

Since its publication, the book has been sold in almost fifty countries worldwide, ranked numerous times on the Amazon bestseller list for books about Parkinson’s and sold over 45,000 copies. In 2016, Marie followed up on the success of the first book with Everything You Need to Know About Caregiving for Parkinson’s Disease.

Born and raised near Toronto, Canada, Lianna Marie now lives with her husband in Seattle, Washington. She is a member of the Author's Guild and the Pacific Northwest Writers Association. When she’s not writing or researching, you’ll find her in the swimming pool, training for her next competition. An accomplished athlete, she has medaled internationally while representing Canada in both modern pentathlon and swimming.
