Board of Directors

Sheila Oliver - Acting ChairSheila Oliver

Sheila has lived in Finchley since 1981 and is married with three adult daughters. After 34 years working in social housing in Camden and Barnet, she retired in 2011 and took up a range of activities locally and in central London, which included working as a volunteer for Barnet Mencap. She became a trustee in 2012 and brings experience of people and organisational management, multi-agency working, service user consultation and, of course, social housing. She has provided support on various fundraising bids and activities such as the “Walk for Wendy”. In future she will be leading for the Board on User Consultation and provide ad hoc support as needed.

Mike Wiffen - TreasurerMike Wiffen

I am a qualified accountant, and I took early retirement from Barnet Homes in December 2010, where I was its Chief Financial Officer.  Previously I worked with Barnet Council for almost 30 years, becoming Head of Finance for both housing and social services.  My education was undertaken at Christ’s College, Finchley where I am now a Governor, and I have an Economics degree from Essex University.  I have two sons, and the eldest, Timothy has Downs Syndrome.  This led me to experiencing Barnet Mencap’s services from the user-perspective through Open Door, which was so supportive in his early years.

I live in Barnet and have been treasurer of the Old Finchleians FC for the last twenty years.  Football is a passion of mine, and I regularly watch Barnet FC. One of my other passions is exploring Europe by train, and this year reached both Krakow and Prague.

Sally WickendenSallyWickenden

Sally has an adult daughter with physical and learning difficulties who has lived in a small residential home in Barnet for the past 8 years and who uses the Day Services in Barnet. Her daughter comes home every other weekend, so she is well aware of the pressures on families who care for a family member with learning difficulties.

She has 2 other grown up daughters and is married to Peter who she met when they were both volunteering at a Gateway Club in Enfield over 30 years ago. For the past 8 years she has worked at Barnet College supporting students with additional needs on specialist and mainstream courses. She has specialised lately by working on the Childcare courses where her experience of having a child with learning difficulties has definitely come in useful.

Outside work and caring duties she enjoys reading, sewing and going to the cinema. She also enjoys walking locally but tries to escape to the lovely Peak District whenever she can for more demanding walks.


We are looking for more voluntary trustees and a Chair. As a voluntary trustee you would be part of a dynamic and dedicated team that focuses on the strategic direction and governance of the charity, and become an ambassador for Barnet Mencap.  Click here for more info
