About me

Qualified counsellor offering a safe, supportive space and a listening ear, to help you work things out and to re-connect you with your own strength, resilience and wisdom. I also offer a range of effective tools to help you deal positively with anxiety, stress, relationship issues and trauma.

My approach is flexible and eclectic, with sessions tailored to meet you needs. Apart from offering standard talk therapy it's also possible, if it suits you, to work with art and creativity, movement, embodiment, and breath and voice-work.

I offer sessions walking in the open air if you would rather not be stuck inside. During covid-19 I can also offer sessions by Zoom.

“From the first meeting with Marcus to the last he was always polite, professional and friendly. He put me at ease whilst talking about difficult subjects and encouraged me to work on issues that presented themselves physically as well as mentally. With his help and encouragement I was able to come to terms with things in my own time and way.” — Anna G.

“I found Marcus to be extremely helpful, and empathetic offering me a way forward when I was going through a difficult period in my life. A great listener and I always left the consultation feeling much better in myself giving me the strength to move forward. A huge support and I would warmly recommend him." — Joy F.

When I first met Marcus I was in a traumatised state from sexual abuse when I was a child. I spent a year in therapy with him and every Tuesday was one more step towards healing. He always made me feel safe and let me set the pace. In the midst of the worst state of anguish he also had the uncanny ability to lighten the intensity and sometimes, surprisingly, could make me laugh before I left the session. He walked alongside me in ways that surprised and encouraged me. Most of all, he is very sensitive and challenged me to be my most courageous self — but 'held my hand' when I felt unable to do it alone. It was worth every bit of courage I had to muster. Getting better is the prize." — Genevieve B.

"Working with Marcus has been life changing, he's helped me realise my body is an ever present resource for self-healing and learning, thank you." M.L.

Training, qualifications & experience

I have an Advanced Diploma in Emotional Therapeutic Counselling and am an accredited member of the National Counselling Society. I have regular supervision, and am fully insured.

Emotional Therapeutic Counselling is a humanistic and person-centred therapy, which means that while I hope to bring insight and helpful perspectives into the work we do together, I won’t ‘diagnose’ you, but will aim for us to explore and dialogue together, as feels right to you. Many people have found that ETC has helped them with a wide range of problems including depression, anxiety, low self-

Embodied Approaches

All of us are more than just a ‘talking head’! It’s increasingly realised that bringing more awareness of the body into therapy can sometimes make things go much more quickly and effectively. For some people, allowing their body to fully feel, express and tell its story can bypass the 'stuck record' of thoughts, beliefs and words and enable them to let go of the past and open up to new experiences and ways of being more quickly. If it fits and works for you I can support you in the sessions to move, vocalise and express, let go of past hurt and trauma, and gently support you to open into new ways of being and experiencing yourself at a physical level. I am also more than happy to work in a more conventional way if that is a better fit for you, or for the issues you are bringing.

My approach to embodied therapy is based primarily on the ‘Body Listening’ approach which I learned at the Brighton School of Embodied Therapy through formal training and ongoing mentorship. I am also a qualified and experienced Alexander Technique teacher, and I teach a therapeutic dance practice called Dance of Awareness.

INFP and INFJ personality types

Lack of confidence
Low self-esteem.

Walking and outdoor therapy. The rhythm of walking can help us to relax and organise our thoughts, and for some people may feel more natural and comfortable than traditional chair-based talk-therapy. I offer sessions walking or just being in nature for those who find this helpful.

Wheelchair user access

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.
