Sara Koster-Marcon

Systemic Family & Couples Psychotherapist

Relationship specialist


MSc, PG Dip CYP IAPT, PG Dip, BSc .

Who I work with

I work with individuals, couples, families and parents.

People come to me on their own as often as they come as a couple. If you are struggling with a relationship, you do not need your partner to be willing to attend for the work to be useful - a great deal can change when one person starts to look at the patterns they are caught in.

  • Individuals - working on relationships, anxiety, confidence and difficult life events

  • Couples - communication, disconnection, affairs, and deciding whether to stay or separate

  • Families - including families with young children, teenagers and adult children

  • Parents - consultations for parents worried about a child's emotions or behaviour, with or without the child present

How I work

I have worked as a systemic psychotherapist for over 15 years, across children's and adult NHS services in London, alongside schools, local authorities and healthcare teams.

My approach is systemic. That means I am interested less in what is wrong with you, and more in the patterns you find yourself repeating - with a partner, with family, and in the story you tell yourself about who you are.

Most of the difficulties people bring to me have a shape to them. Something happens, you respond in a way that once made sense, the other person responds to that, and the two of you end up somewhere neither of you wanted to be. Together we slow that sequence down and look at it properly.

What sessions are like

Sessions are collaborative and paced to you. Over time we will:

  • Identify the patterns of relating and coping that are keeping you stuck

  • Explore the beliefs you hold about yourself, about others and about past events, and how these shape what you feel and do

  • Build your ability to recognise what your body and nervous system are telling you

  • Develop steadier ways of managing strong feelings, both on your own and with the people close to you

  • Find the resources that already exist in you and in your relationships

The aim is a settled and connected sense of who you are, both by yourself and with others.

Life events often bring people to therapy - moving home, a new job, a birth, a bereavement, a break-up, an affair, or communication that has quietly broken down. These are exactly the moments when it helps to have somewhere to think.

Client testimonials

Sara Helped Us Reconnect and Strengthen Our Marriage After 15 Years

“My husband and I were struggling with our marriage and lack of communication after 15 years together. Reaching out to Sara was the best decision in order to get us back on track. She really challenged us to think about so many aspects and influences that were affecting us as individuals and also as a couple. She is a warm, friendly and open therapist who I have no hesitation in recommending.” Anonymous Couple

Sara’s Supportive Guidance Transformed My Thinking and Behaviour

“Sara has a wonderful manner with her clients. I felt very comfortable speaking to her and opening up to her (which is one of the main reasons I sought out therapy in the first place.) Sara challenged me in my ways of thinking and ensured I was thinking analytically about my behaviours and actions, in a supporting and safe way. I felt an enormous sense of achievement after our sessions and felt like Sara celebrated this.” Jodie

A Warm, Approachable Therapist Who Put Us at Ease

“Sara was an extremely approachable and knowledgable therapist. She put us both at ease and was able to use her skills and experience to guide and structure our sessions.” Anonymous

Sara Helped Me Find My Confidence and True Self

“Sara has helped me find my real self. She guided me session by session with clear goals about what I wanted to get out of our meetings. She is very warm and made me feel comfortable when talking about difficult stuff. I now feel more confident and see life from a happier place.” EM

Sara Guided Our Family Through Challenges and Improved Communication

“After our sessions I thought everyone should have family therapy! Our son started to have behavioural difficulties at school. We couldn’t see a way out. She helped us see the problem from a wider perspective and not make him the problem. We can now all see what we do to contribute to that. We found better ways of communicating our emotions and be there for one another. Sara also helped us set up meetings with the school to make sure we are all on the same page in supporting him.” AW

Marriage Saved Through Sara’s Transparency and Patience

“My wife and I were struggling in our marriage for a long time. The sessions with Sara helped us finding solutions to our issues. We now feel equipped to talk to each other and enjoy our marriage again. I was initially reluctant. Her transparency and patience helped me see the benefits of therapy.” DM
