chief executive

Derek Heath

Derek started working within Supported Housing over 18 years ago. He began as a trainee Support worker at a large hostel in central London and was soon promoted to a drug and alcohol worker specialist. His first managerial role came after 12 months when he was asked to manage a 10 bed third stage house for clients completing Residential Rehabilitation. After five years at Irish Centre Housing, he became an Operations Manager for English Churches Housing Group, managing two services supporting sex workers and clients with varying alcohol and drug and complex mental health needs. When funding was removed for both services Derek took on a new challenge, developing and managing a new 25 bed hostel for armed forces veterans. After three years building up the service, he recognised that he still had unfinished business with his first love, developing alcohol and drug services, and the opportunity to work for a small and innovative charity like Druglink was too hard to resist. Derek has been at Druglink for five years, in which time he has developed and overseen the Oxygen Recovery pathway which is now able to offer clients two years of supported recovery.




director of care & support

Wendy Nee

Wendy began her career in substance misuse fifteen years ago as a volunteer. She undertook counselling training and soon became a fully-fledged member of a Recovery Team. After undertaking CPD and management training she progressed through a number of leading organisations in the field, working her way up to Service Manager – largely in community-based services.  Joining Oxygen was Wendy's move into residential rehabilitation, and the best move she ever made. Wendy sees it as a privilege to be part of a clients' journey from admittance to graduation. She is a qualified trainer and counsellor, a published freelance writer and nearing the completion of an NVQ level 5 in Leadership & Management in Health & Social Care, plus she has two BA degrees. Wendy enjoys spending time with her three teenage children, watching rugby, tap dancing, meditation, cookery and reading.




service manager

Gary Aldridge

Gary started his career as a Recovery Champion at a treatment centre, supporting those arriving into treatment.  As he progressed in this role, he began to see a career path ahead of him and wanted to help people on their path to recovery. He was given his first paid employment as a night worker, concurrently completing the first part of a counselling qualification. Whilst competing the second year, he was employed as a counsellor at Druglink. From this position he has progressed through the ranks and is now Senior Practitioner. Gary has a level 4 counselling qualification and is currently working towards an accreditation. He has just started his level 4 qualification in health and social care and this year he will also be completing a Gestalt group facilitation qualification. Gary is very grateful to be in a position where he can aid people on their recovery journey.

recovery worker

Hema Yagambrun

Hema has been working at Oxygen for nine months as a Waking Nights Worker and recently began her role as Recovery Worker. Prior to working at Oxygen she spent ten years as an English teacher, but left this to study an MA in Criminology at BCU. As a result, she became interested in working in the field of crime and an its inevitable association with addiction. During her time as a teacher she saw how badly addiction affected her students’ lives and wanted to help them in a more direct way by working with addicts and their families. Hema's hope was to eventually become a recovery worker and aid those affected by crime and addiction to overcome this and lead fulfilling lives. Hema lives with her husband, father and a clowder of cats, and is hoping to move onto her husband’s narrowboat, which they are currently renovating.


support worker

Dean Toner

Dean started at Oxygen as an Apprentice Recovery Worker in September 2015. After 18 months of extremely hard work, he has recently become a full time member of the team. He loves his job, especially as he sees a client change and develop as they journey through their recovery. Dean is currently studying level 2 counselling and level 3 health and social care. He is hoping to further his studies in level 3 substance misuse. In his spare time, Dean loves going to the gym, eating healthily and spending time with his girlfriend.
