Daven Masri

Daven is an ISHA shared owner. Being able to own a portion of his own home so improved his life that he was inspired to apply for a Board Member role to ensure that others could continue to benefit from the same opportunity. He hopes that his resident’s perspective will serve the Board well and lead to more affordable homes that enrich the communities ISHA operates within.

An environmental engineer for more than 10 years, Daven is a Founding Director at Wave Consulting Digital Engineers which focuses on Building Information Modelling (BIM) and environmental design. He strongly believes in creating homes that perform well, using fewer resources in construction and occupancy.

June Riley

June began her training in accountancy by entering the NHS as a graduate trainee shortly after leaving University. She is a qualified accountant and completed an accredited MBA with Manchester Business School to add value to her career as an accountant.

June has worked in housing for almost 20 years and was a Finance Director in a housing association managing over 17,000 homes. She is now a Group Finance Director in one of the largest mental health charities in the country.

June has served in a voluntary capacity on several Boards, including Newham Homes Ltd, which was managing over 27,000 homes. She is currently serving as a Senior Independent Director on The Barnet Group Board and is pleased to be a Non-Executive Director on ISHA's Board.

Mohammed Baporia

Mohammed is an ISHA shared owner. Like Daven, his personal experience inspired him to apply for a board member role. Mohammed is keen to give back to the community and help ISHA to deliver quality and truly affordable housing to those that need it most. As a resident, he aims to ensure the high standards set by ISHA’s Board are being met.

Mohammed is a qualified accountant and tax manager on the real estate and construction team at a global accountancy and business advisory firm.

Yasmin is a solicitor specialising in property law and has considerable experience in property law both in the public and private sectors. Yasmin has strong customer facing skills and experience in both property and employment law, and aims to bring these skills to benefit ISHA in helping to improve its customer service, as well as her genuine interest in helping to deliver safe and affordable housing for those in need.

John Biggs

John joined the Board in September 2022. He was the Executive Mayor of the London Borough of Tower Hamlets from 2014 to 2022 and a former London Assembly member. For several years, John was also an active social housing resident in his local residents’ association.

John shares ISHA's frustration with the current climate of ‘unaffordable affordability’ and believes we must challenge this in our policies, particularly in the current cost-of-living crisis. John also believes that by working with residents, and other partners, ISHA can help address the problems of inequality that place people in positions of financial or other vulnerability.

London has given John and his family great opportunities and he wants to give back to future generations.

Alwyn Lewis

Alwyn Lewis is the former Chief Executive of Hornsey Housing Trust and has had a 40-year career in the third sector.

He has a track record in social housing and a reputation for putting tenants first and for making things happen. He was attracted to the role at ISHA because of our strong social purpose, our desire to deliver high-quality services and to positively effect social change, especially with ethnically diverse communities who experience social and economic disadvantages.

Alwyn shares ISHA's vision to working with us and residents to co-create homes and communities where everyone can flourish.

Ruth Davison

A passionate believer that mixed communities work best for everyone and help make great places, Ruth is proud to lead ISHA as CEO. Building genuinely affordable rented and shared ownership homes and being a fantastic landlord - helping both communities and individuals flourish – is what motivates her.
