What brings people to therapy
You don't need to have everything figured out before getting in touch. Most people reach out when something in their family feels stuck, painful, or hard to talk about.
Family relationships feel stuck
Constant arguments, silence, distance, or a sense that you're all walking on eggshells. Family therapy can help you hear each other again — and find a way through.
Your relationship needs support
Trust has been broken. Communication has dried up. You're separating and want to do it well. Couples therapy offers a safe space to work things through together.
Addiction is affecting your relationships
A partner's drinking, a child struggling with addiction, a sibling in crisis. You may be feeling exhausted, worried and unsure how to help. You don't have to carry this alone.
How I can help
My approach is systemic and relational, looking at the bigger picture of relationships, patterns, and life circumstances, rather than focusing on one person in isolation.
General practice
Families, Couples & Adolescent Therapy
I work with children, young people, adults, couples, and families experiencing a wide range of emotional, relational, and life challenges. Systemic therapy works with the relationships between people, not just individuals. Whether you're navigating conflict, a life transition, parenting challenges, or simply want to communicate better — I offer a warm, non-judgmental space to explore what's happening and find a way forward.

Specialism
Addiction & Relationships
A partner's drinking, a child struggling with addiction, a sibling in crisis. You may be feeling exhausted, worried and unsure how to help. Recovery can bring its own challenges too — as people make significant changes, relationships often need time to adapt. Whether you are affected by someone else's addiction or navigating recovery yourself, therapy can help create meaningful and lasting change.

About Rebecca
15 years working alongside families through difficult times
I am a qualified systemic and family psychotherapist. I trained at the Institute of Family Therapy (IFT), one of the UK's leading training institutions for systemic practice, where I completed my MSc in Systemic Psychotherapy. My training included over 300 hours of live clinical supervision with families.
Before training as a psychotherapist, I spent 15 years working with families affected by substance use and additional challenges, in both prison and community settings — across the voluntary sector, local authority, and the NHS.
My research explores how hope is experienced and sustained by families affected by addiction — not as a feeling you either have or don't, but as something actively done and shared within relationships.
What to expect
Therapy should feel safe, human, and genuinely useful. Here's what working with me looks like.
Safe & confidential
A non-judgmental space where everyone's experience is heard and respected.
Whole-family thinking
Systemic therapy looks at relationships and patterns, not just one person.
Realistic hope
Change is possible, even when things feel stuck. We work with what's here.
Warm & steady
I bring warmth, consistency, and a genuine belief in your family's capacity to change.
What families say
Anonymised feedback from families I've worked with.
“There's an unmistakable sense of Rebecca's ethical values — a belief in the goodness in people, even when they do bad things; a belief in people's and families' capacity to change, to repair and to recover.”
Parents of a young adult in recovery from substance use
“This has been one of the most transformative therapeutic environments I've ever been in. It was a very safe space and I've learnt so much that I will carry forward.”
Adult child managing the impact of a parent's addiction
“This experience has given me more hope for our family's future. We've seen real, even if gradual, change, and I feel like we're now better equipped to face challenges together.”
Family member
“My definition of hope has changed. Before it felt like a wish and quite scary. Now understanding cycles of recovery and change and my own level of control makes me feel more hopeful. It's okay to be hopeful and also realistic about what I can and can't control.”
