Mrs. Ruth Coleman


Ruth became a Member of PQI in 2010 and has served on the Management Committee since October 2012.

Ruth has also been a passionate Support Group Coordinator since 2013, and a person with Parkinson’s, and feels she can contribute to the Parkinson’s Queensland team in many diverse ways. 

Ruth committed to the term saying that she would like to ‘complete the tasks I have undertaken to guide Support Groups and their Coordinators to an improved pathway, as we continue to strive towards our Strategic Plan. My understanding of the governance function and experience at Management Committee level has been gained from being a Committee Member of PQI since 2012.’

Ruth’s unwavering commitment to PQI stems from not only being a person living with Parkinson’s, but from connecting with like-minded people at our support groups.

Ruth says, ‘To be told you have Parkinson’s is life changing and finding a Support Group was my lifesaver. My mission now is to promote these groups and to reach out to support people living with Parkinson’s.’

Mrs. Judy Learmonth


Judy sees the role of Support Groups as important to PWP, Carers and Family members.

Judy’s experience as a Support Group Coordinator strengthens this claim as many, given the devastating news, know little about Parkinson’s or what to do next.

Judy has followed many Support Group members as they endure the impact of Parkinson’s, not only on their life, but the lives of family members and friends.

Judy’s husband had Parkinson’s and this has given her a greater understanding of their trials and tribulations. Judy works closely with PQI as a Support Group Coordinator and she supports PQI’s Strategic Plan and identifies strongly with the key characteristics enabling PQI to one day reach out to all Persons with Parkinson’s to offer the required support.

Judy has extensive work experience with private business enterprises and with Local Government and holds a Bachelor of Business majoring in Management and Marketing.

For over 7 years she has been Support Group Coordinator of the Elanora Support Group (Gold Coast) and routinely travelled to Elanora from Bargara (Bundaberg) to chair their meetings. Why? As the group was unable to find a replacement coordinator, Judy’s unwavering commitment to people with Parkinson’s on the Gold Coast, meant that Judy continued to run the group she helped to found.  

As a wife and carer of many years (Judy’s husband deceased 2015), Judy has travelled the Parkinson’s journey and can offer members the understanding, sympathy and hopefully guidance during difficult times.
