Thomas Brosnan - Addiction & Behaviour Specialist

About me

I am an experienced Integrative Addiction and Behaviour Therapist who works with children, adolescents, adults, families, couples and groups. I hold a Masters in Addiction Psychology and Counselling, a Level 4 Certificate in Counselling Children and am a Registered Member of the British Association of Counsellors and Psychotherapists (BACP). I am also an Accredited Member of the Federation of Drug and Alcohol Professionals (FDAP), a Member of the British Psychological Society (BPS), a Certified Motivational Interviewing Practitioner and a Level 2 iheart Facilitator.

For over 20 years, I have supported people to flourish in a range of personal, social, emotional, academic and professional environments. I have experience of working in both public and private rehabilitation sectors such as The Priory and also occupy a position within the NHS as an Addiction Therapist.

I am extremely passionate about child welfare as I firmly believe that if we don't have broken children, we are much less likely to have broken adults. As a result, I strive to implement, research and develop early intervention strategies for young people where my current research piece concerning metacognitions, parenting styles and cannabis use has recently been published. I also speak publicly and have recently featured at the Harrow SEND Conference and sat on a panel of experts for the annual Disordered Eating Conference which was held at London's St. Pancras Hospital.

I have a warm, person-centered and solution-focused approach to my therapy where I uphold that every person has the innate ability to thrive. By focusing on the trinity of thoughts, feelings and behaviours, I enable my clients to identify where their issues lay and to notice how and where they can make positive choices that are right for them.

In concluding work with me, clients report having increased levels of confidence, self-esteem and autonomy which lead to them being more resilient, having a greater level of emotional intelligence and a better sense of self overall.

Member organisations


British Association for Counselling & Psychotherapy

BACP is one of the UK’s largest professional bodies for counselling and psychotherapy. Therapists registered with the Association fall into a number of different membership categories such as Individual Member, Registered Member MBACP and Registered Member MBACP (Accred), each standing for different levels of training and experience. MBACP (Accred) and MBACP (Snr Accred) members have achieved a substantial level of training and experience approved by the Association.

Registered members can be found on the BACP Register, which was the first register to achieve Accredited Voluntary Register status issued by the Professional Standards Authority. Individual Members will have completed an appropriate counselling and/or psychotherapy course and started to practise, but will not appear on the BACP Register until they've progressed to Registered Member MBACP status.

All members are bound by a Code of Ethics & Practice and a Complaints Procedure. Accredited by the Professional Standards Authority.

Wheelchair user access

Wheelchair-accessible premises should have step-free access for wheelchair users and individuals who are unable to climb stairs. If a counsellor's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the counsellor to discuss the options available.

Under the Equality Act 2010 service providers have a duty to make reasonable adjustments to ensure that individuals with disabilities can access their service. You can read more about reasonable adjustments to help you to access services on the CAB website.
