Gill Arukpe

Group Chief Executive

As the Group Chief Executive, Gill founded the Social Interest Group in 2014. The Group supports over 11,000 people a year in areas of resettlement, rehabilitation, social and mental health care and support.

Gill has led successful health and social care services for over 35 years. Her dedication to the sector stems from her own experience of homelessness in the late 70’s.

She is an expert at strategic planning, service development and risk management in social and health care and working within the criminal justice world.

Gill has developed flagship services working with treatment resistant street drinkers, women who are sexually exploited and adults who have failed in other services as their needs were deemed to be too complex and chaotic because of their mental health or personality disorder.

Gill took a brave step into the world of probation by taking part in the London CRC. The learning from which is enabling her to work with her team to develop offender services, ensuring excellent employment opportunities and support is available for offenders leaving prison who need support with rehabilitation.

She is passionate in her resolve to encourage experts by experience, to be leaders within the development of the services within the Group.

Darren Kelso

Director of Mental Health, Alcohol & Substance Misuse services

Darren Kelso is the Director of Mental Health, Alcohol & Substance Misuse services. He has worked with Penrose from 2012 and therefore the Social Interest Group from its inception. He currently works with a team of 5 senior managers who work across the London and Brighton areas, along with responsibility for gender based systems change which reaches across the entire group.

Darren has followed several career paths, mainly in opportunities which allowed him to lead and develop teams or individuals. He moved into the social care area in 2008 after a series of interactions with people who seemed unable to get support for the difficulties they were facing. This led him to work directly with individuals with enduring mental health and substance misuse issues. He then worked within youth hostels in Luton and as manager of the Temporary Accommodation Support Team. He was part of SIG’s Luton and Bedford management and remained primarily involved in the adoption of the best ways of working along with monitoring of quality and efficiency.

Darren is a member of the South Bedfordshire RSPCA board of trustees and enjoys nothing more than listening to live music, everywhere from a dingy basement venue up to an arena show.

Greg has worked in the charity sector for 20 years, starting out as a Team Leader for the Prince’s Trust covering Lewisham in 1999. Greg has a passion for volunteering and worked at Volunteering Matters (formerly CSV) for 11 years, bringing volunteers from all around the world together to support vulnerable people within the UK. He took his first Business Development role in 2007, then continued his career in development at Choice Support, writing tenders and building support packages for people with learning disabilities.

Greg sees his development of the Penrose Community Links service, which provides individualised support for people with complex needs within their own home or in the community as his greatest achievement at SIG so far. “I absolutely love working within the Group and am very proud of the work we are doing to enhance the lives of the people we support.”
