Jo Groom

Treasure Keepers Manager

Therapeutic Approach Social Worker

BA (Hons) First Class

Registered with Social Work England

I have specialised in working with ‘Looked After Children’ since becoming a Social Worker in June 2015. This group of children and young people have experienced early life trauma, which for some is a complex trauma of multiple events over their lifetime.

These children and young people are in need of support from a specialist service to enable them to process and understand their past to not allow it to define their futures.

Treasure Keepers ® work with children and young people to work through their complex trauma giving them the tools to ‘Shine’. All children and young people deserve to be the best they can be.

I strongly believe that therapeutic relationships that nurture, accept and encourage children and young people are the basis for their success. These relationships should be with the adults and carers who have the most contact with the children and young people a service like Treasure Keepers is able to provide the knowledge of implementing a therapeutic approach to relational interaction and provide the ‘stability’ all children and young people need.

I have two children living at home aged 11 and 16 and older children who are now adults and flown the nest.

I enjoy meditation, yoga and running.

Lucy Robertson – Ritchie

Systemic Family Psychotherapist

“What I love about the Treasure Keepers model is that it combines evidence based theory to help heal difficulties where there has been developmental trauma. This way of working provides quality holistic, individualised therapeutic input for individual children and young people and their parents and carers. I work collaboratively with children, young people and their families to help support them work out what will work best for them and their families.

I offer individual, couple and family systemic therapy, consultation and supervision and have facilitated therapeutic groups for children, teens and parents. I use the Treasure Keepers model to work with families.

This is a no blames approach that treats people with respect whist helping them improve communication, mood and relationships.

I am a UKCP and AFT registered systemic family psychotherapist and I have 14 years post qualification experience working in an NHS Child and Adolescent Mental Health Service and in independent services with childrens, teenagers, parents and carers. I have 5 years experience teaching systemic psychotherapy for the Institute of Family Therapy and at the Tavistock and Portman NHS trust. I am also a qualified yoga teacher and can offer therapeutic yoga sessions individually and in groups.

I have three daughters who are 5, 10 and 13 years old.


Eileen Sullivan

Integrative Therapist 

“I am an Integrative Therapist specialising in Child & Adolescent Mental, Emotional and Neurodevelopmental Disorders. I have an interest in the field of developmental trauma and the subsequent impact this has on the developmental trajectory of children and adolescents. The impacts of which can have lifelong effects on human functioning. I passionately believe that timely and appropriate interventions can mitigate the traumatic experiences suffered by the children and adolescents that come to specialised services, such as Treasure Keepers. Giving them the opportunity to move forward in their life journey with the possibility of optimal outcomes for each of them individually.

I have worked in this field for 20 years gaining experience from employment within the NHS, voluntary and independent sectors. I have always felt privileged to be able to do this work. My professional body is the BACP and I adhere to the code of ethics and practice as described on the BACP website.

Becki Donn

Therapeutic Counsellor - BACP Registered

I am a Therapeutic counsellor with an Integrative approach. I have worked with Children and Young People for 10 years in a variety of settings within voluntary, public and private organisations. I have a keen interest in Mental Health and Neuro-Developmental concerns. My experience has enabled me to work with a range of Children, Adolescents and Adults with complex needs and I am able to offer a holistic approach to all of my clients. My main goal in my work is to treat all of my clients with dignity and respect and to build trusting and therapeutic relationships with those I work with.


My experience in the NHS has taught me to ‘Think Family’ first and foremost for those Children and Young People I work with. I incorporate the needs of the Children and Young People alongside the needs of the whole family into my formulation of intervention that I am delivering. This has given me the experience to work in a Multi-Agency/Joined up way.


I work alongside Social Care, Schools, Youth Offending Teams, Drug & Alcohol Services, Child & Adolescent Mental Health Services, Adult Mental Health Teams and Voluntary Providers in my everyday work.


I take Continuing Professional Development seriously and strive to develop and grow as a practitioner to better the outcomes for my clients. The most important education I receive comes from those who I am delivering interventions. My clients are my greatest teacher and I feel privileged to be a part of their journey
