Dr Guy Maissis, Clinical Psychologist

I am Dr Guy Maissis, an accredited Clinical Psychologist providing evidence-based therapies online and in-person in London since 2015.

Alongside my work in the NHS as a Service Lead specialising in physical health conditions (in particular Cancer and Haemophilia), I offer private therapy to support clients who require the flexibility and the individual-tailored approach enabled by the private setting.
I view therapy as an opportunity for my clients to share their stories, reflect on their experiences and identify what and how they would like to change their lives. I practice a variety of therapeutic models, including Third Wave CBT, Mindfulness and Psychodynamic therapy, and I use my clinical expertise to tailor the intervention to my clients’ needs. I see both individuals and couples and I practice fluently in both English and Hebrew.
My particular areas of expertise are: cancer and long-term health conditions, interpersonal relationships, relationship with self (self-esteem, perfectionism and self-criticism), mood issues (anxiety and low mood), and matters relating to sexual identity and practice.

I am a registered provider with the following healthcare insurance companies: AXA Health, Aviva, Vitality Health and Cigna.
