About Me

I typically work with people wrestling with anxiety, despair, anger, and shame; who struggle with guilt, mistrust, addiction, and dissociation; who are self-critical, self-destructive, and who feel trapped in repeated patterns of hurting self and others. Such feelings, behaviours, and patterns of relating often stem from multiple and complex life events and circumstances, including past and present abusive and neglectful relationships, abandonment, bereavement, bullying, trauma, racism, sexism, gender expectations, parenthood, study/work/financial pressures, and more existential challenges such as finding meaning in life.

I offer a warm, nurturing space in which, collaboratively, we can explore and make sense of difficulties you are facing. My training in Counselling Psychology means I am skilled in working integratively, that is using several therapeutic approaches including systemic, internal family systems (IFS), psychodynamic, and existential models, and able to tailor my work to meet your specific situation. Primarily, my style is relational and contextual.

I am presently seeing clients in person and online. I also have a limited number of slots available for outdoor walking therapy. Please contact me if you would like more information, by email as I am mostly unavailable by phone.

I offer free initial (scheduled) phone consultations of up to 20 minutes. I have a small number of discounted slots available for people on lower incomes and students.



As part of my affiliation with the Institute of Psychedelic Therapy (, I presently offer one-to-one support for people who have had challenging experiences on psychedelics, and/or those who are planning on using psychedelics, including via legal retreats in the Netherlands. I am also presently accepting expressions of interest for participation in the following Psychedelic Integration Group:


Psychedelic Integration Group

In recent years, we have seen a remarkable worldwide renaissance of interest into the therapeutic potential of psychedelics, with many thousands of people embarking upon psychedelic journeys in the present time. Such journeys can be joyous, liberating, disorienting, and terrifying. As such, integration work is essential for processing experiences and insights, commonly rendering these experiences and insights useful in the process of therapeutic growth, and healing. 

Because, however, psychedelics are currently illegal in the UK, competent, experienced, considered, and containing support can be difficult to locate. As such, many people are entering into psychedelic 'trips' without adequate support to make sense of often challenging journeys. This state of affairs increases risks of harm. 

Together with a small group of fellow psychologists and psychotherapists, I am presently running a Psychedelic Integration Group in Brighton, for those who have used psychedelics, or are considering using them. The main aim of this group is to provide a safe space for people who have had challenging psychedelic experiences and want to make sense of these, who wish to share meaningful experiences, and/or who wish to learn more about psychedelics, with harm reduction in mind. This group runs fortnightly on a Friday, 1pm til 3.15pm, and is charged on a sliding scale from £25 to £40 per session. 

In accordance with the law, the group does not provide psychedelics, nor permit use of psychedelics during group meetings, nor offer referrals to illegal psychedelic services. Neither myself nor my colleagues encourage the use of psychedelics in illegal contexts, while at the same time recognising that many people are choosing to use psychedelics in this way. Again, the primary purpose of this group is to offer integration and preparation support, in order to reduce the potential for harm.
