Addiction Specialist & Psychotherapist

About me

I would like you to know that your life matters to me and I am pleased that you have decided to take the step to improve your life and deepen the understanding you have about yourself. 

I also appreciate that you are considering working with me so let me tell you a little bit more about myself and my practice. 

I am an open, honest and experienced Integrative Addiction Specialist and Psychotherapist where for over 20 years, I have supported children, adolescents, adults, couples, families and groups 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 the NHS and also, within the SEND community too.

I hold a Masters in Addiction Psychology and Counselling, a Post Graduate Certificate of Education, a Level 4 Certificate in Counselling Children and an Advanced Diploma in Couple and Relationship Therapy. 

Further to this, I am a Registered Member of the British Association of Counsellors and Psychotherapists (BACP), an Advanced Practitioner and Accredited Member of the Addiction Professionals (formerly FDAP), a Certified Motivational Interviewing coach and a Level 2 iheart Facilitator. 

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 and techniques for young people where my research includes a first of its kind publication combining metacognitions, parenting styles and cannabis use and more recently, a piece on exercise addiction for Cambridge University Press. 

I also host mental health workshops for MIND and speak publicly where I feature at the annual Harrow SEND Conference. I have also sat on a panel of experts for the Annual Disordered Eating Conference which was held at London's St. Pancras Hospital and am currently supporting the East London NHS Foundation Trust and BEAT develop PSHE lessons for schools around healthy eating.

My approach to therapy is inclusive, warm and person centered yet solution-focused and curious. I uphold that every person has the innate ability to thrive and by focusing on the trinity of thoughts, feelings and behaviours from the first session, I create a safe space for  my clients to establish their aspirations, their purpose and their passions to identify where their issues lay to notice how they can make healthier choices that are right for them.

In concluding work with me, clients report to having increased levels of confidence and a higher degree of autonomy which lead to them being more resilient and having a  better sense of self overall.

Member organisations


British Association for Counselling & Psychotherapy (BACP)

BACP is one of the UK’s leading professional bodies for counselling and psychotherapy with around 60,000 members. The Association has several different categories of membership, including Student Member, Individual Member, Registered Member MBACP, Registered Accredited Member MBACP (Accred) and Senior Registered Accredited Member MBACP (Snr Acccred).

Registered and accredited members are listed on the BACP Register, which shows that they have demonstrated BACP’s recommended standards for training, proficiency and ethical practice. The BACP Register was the first register of psychological therapists to be accredited by the Professional Standards Authority (PSA).

Accredited and senior accredited membership are voluntary categories for members who choose to undertake a rigorous application and assessment process to demonstrate additional standards around practice, training and supervision.

Individual members will have completed an appropriate counselling or psychotherapy course and started to practise, but they won’t appear on the BACP Register until they've demonstrated that they meet the standards for registration. Student members are still in the process of completing their training.

All members are bound by the BACP Ethical Framework and a Professional Conduct Procedure.
