Working with individuals to understand themselves more deeply — and find their way forward with greater clarity and ease.

I am a Consultant Clinical Psychologist with over 25 years of experience working with adults and young people experiencing a wide range of difficulties — from anxiety, depression and trauma to life transitions, grief, relationship challenges, and questions of identity and meaning.
Throughout my career I have supported people in finding ways to manage emotional distress and live more creatively. I often explore with clients how art, poetry or music can help them manage severe emotional pain and connect more deeply with themselves.
My approach draws on a range of evidence-based therapies, including Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), Compassionate Mind Therapy, and Internal Family Systems (IFS) therapy. I tailor my work to each person, believing that no single method fits everyone.
I also work as a Leadership Consultant, drawing on management training completed in 2022 which encompassed individual and team coaching, mentoring, navigating organisational politics, managing difficult conversations, and understanding personal strengths and vulnerabilities as a leader. I have worked extensively within the NHS and with corporate clients, many of whom present with emotional difficulties arising from work-related stress. I bring both psychological depth and practical experience to this work.
I run a private practice in Hertfordshire and offer face-to-face sessions to clients who can attend in person, as well as online sessions for those unable to do so due to distance. I offer a gentle and exploratory space where you can take the time to reflect on your current difficulties, as well as their deeper roots — and come to a place of deep healing and understanding of yourself, your relationships, and your life.
"After years of struggling with depression, anxiety, and intense emotions, I'd tried therapy before but still felt stuck. Mariette gently helped me see what I'd been avoiding — and that made all the difference. I now approach everyday challenges with so much more calm, feel truly connected to myself, and have a greater appreciation for all parts of who I am. She created a warm, safe, and nurturing space with incredible patience. Investing in therapy has been the best decision I've made — for myself and my family."
— Rachel, Individual Therapy"I came to therapy struggling with anxiety rooted in teenage trauma, which made work incredibly stressful and left me easily triggered by criticism for days at a time. It also held back my ability to trust in relationships. Mariette's focus on healing has been truly transformative — before working with her, I couldn't speak about my past without breaking down, but now doing so is infinitely less painful. I've learned to understand and accept my feelings rather than fighting them, and when difficulties arise, they no longer consume me for days. There is no wiser way to spend your money than to heal yourself, as the benefits will last forever. Mariette's therapy has hugely improved my life and I feel that I am blessed to have found her."

Leadership can be one of the most rewarding — and most isolating — positions to occupy. The demands placed on managers, clinical leads and executives are considerable, and the emotional weight of that responsibility is rarely acknowledged.
Drawing on management training completed in 2022 and extensive experience working within the NHS and with corporate clients, I offer a confidential space for leaders to think, reflect and grow — separate from the pressures of the organisations they serve.
