Kellie’s Approach and Qualifications
Kellie offers a warm, thoughtful and collaborative approach to therapy. Her work is person-centred, trauma-informed, psychodynamically informed and attachment based, recognising how our relationships and life experiences can shape the way we feel, think and relate to others.
Rather than focusing only on symptoms, Kellie works alongside clients to understand the experiences and patterns that may lie beneath emotional distress. She adapts therapy to each person's individual needs, communication style and strengths, creating a therapeutic space that feels safe, flexible and responsive. This approach is particularly valuable for children and adults who have experienced trauma, are neurodivergent, or have found it difficult to feel understood in previous relationships or services.
Alongside talking therapy, Kellie also offers Art Psychotherapy where it may enhance the therapeutic process. Creative work can provide another way of exploring experiences that feel difficult to put into words, although there is never any expectation to use art. Sessions are always guided by what feels most appropriate for the individual.
Relational Trauma
Relational trauma can have a lasting impact on self-esteem, trust and the way we experience ourselves and our relationships. Kellie works with adults and young people who have experienced domestic abuse, narcissistic abuse, betrayal trauma and other forms of emotionally harmful relationships.
Drawing on her attachment-based, psychodynamic and trauma-informed approach, Kellie helps clients understand how these experiences may continue to influence their emotions, relationships and sense of self. Therapy offers a safe and compassionate space to explore the effects of coercive control, emotional manipulation, repeated invalidation and other relational wounds at a pace that feels manageable. As understanding develops, clients can begin to rebuild confidence, strengthen their sense of identity and develop healthier ways of relating to themselves and others.
Kellie has a particular interest in supporting male survivors of narcissistic and emotionally abusive relationships, recognising that these experiences often go unseen or are difficult to talk about. She offers a confidential and non-judgemental space where clients can begin to process what they have been through and move towards recovery.
Where appropriate, Art Psychotherapy may also provide another way of processing experiences that feel overwhelming or difficult to express in words.
Anxiety, Low Mood and Emotional Wellbeing
Kellie supports people experiencing anxiety, depression, low mood, emotional overwhelm and difficulties with self-esteem. She also works with stress, bereavement, life transitions and relationship difficulties that are affecting emotional wellbeing.
Using her attachment-based, psychodynamic and person-centred approach, Kellie helps clients understand the experiences and relationship patterns that may be contributing to their distress. Therapy offers space to make sense of difficult emotions, develop greater self-awareness and find healthier, more sustainable ways of coping.
Art Psychotherapy
Art Psychotherapy is an established form of psychotherapy that combines creative expression with talking, guided by a trained therapist. No artistic experience or ability is needed. The focus is not on producing artwork, but on what the creative process and the images represent for each individual.
Using art materials in a safe and supportive environment, clients can explore complex emotions, process trauma and express thoughts and feelings that may be difficult to put into words. Artwork often becomes a bridge to understanding, insight and emotional regulation.
Kellie works collaboratively with clients to explore the thoughts, memories and relationship patterns that emerge through the creative process, helping them make sense of past experiences, deepen self-awareness and move forward with greater clarity and confidence.
Clients can choose to work entirely through talking therapy or combine conversation with creative work, depending on what feels most helpful.
Children and Young People
Kellie has extensive experience supporting children and adolescents across educational, healthcare and community settings.
She works with young people experiencing attachment difficulties, trauma, anxiety, developmental differences, emotional regulation difficulties, questions around identity, family change and experiences of loss. Using an attachment-based, trauma-informed approach, Kellie creates a safe and trusting therapeutic relationship where children and young people can explore their thoughts and feelings in ways that feel appropriate to their age, communication style and individual needs.
Kellie has particular experience supporting neurodivergent children and young people, including those with Autism and ADHD, and understands the impact that sensory differences, communication styles and emotional regulation can have on everyday life.
Where appropriate, she works collaboratively with parents and carers to strengthen emotional communication and support the wider family. She also offers Dyadic Art Therapy to help rebuild safety, emotional connection and communication within parent-child relationships following trauma.
Educational Consultancy and Parent Support
Alongside psychotherapy, Kellie offers educational consultancy and parent support, drawing on more than 20 years' experience across mainstream education, alternative provision, the NHS and social care.
She works with parents who are navigating concerns around their child's emotional wellbeing, learning needs, Autism, ADHD and other neurodevelopmental differences. This may include helping families understand available support, liaising with schools and other professionals, and exploring educational pathways that best meet a child's needs.
Kellie also provides consultation and clinical supervision to schools, educational settings and mental health teams, supporting professionals working with children and young people with emotional, behavioural and developmental needs.
Other Areas of Practice
Kellie has extensive experience supporting adults and young people with Autism, ADHD and learning disabilities in both educational and NHS settings. She works with clients who are diagnosed or undiagnosed, and with individuals who are verbal as well as those who communicate in other ways.
Her experience includes supporting people with communication differences, sensory needs and emotional regulation difficulties. Therapy is adapted to each person's individual strengths, communication style and needs, helping clients better understand themselves and develop practical ways of managing everyday challenges.
For clients who find verbal communication difficult, Art Psychotherapy can provide another way of expressing thoughts, feelings and experiences. Throughout her career, Kellie has worked closely with Speech and Language Therapists, Occupational Therapists and multidisciplinary teams. She has also developed creative interventions, including Makaton timetables and "found objects" groups, to support communication and emotional expression.
Kellie's professional experience also includes working in forensic settings and supporting individuals who present with challenging behaviours. She has completed the Oliver McGowan Mandatory Training in Learning Disability and Autism, further strengthening her work with neurodivergent clients and people with learning disabilities.g difficulties with warmth and sensitivity, especially when parenting pressures, neurodiversity, or complex emotional histories are shaping the relationship.
Kellie offers counselling and psychotherapy to teenagers, adults, couples and older adults from our Blackheath clinic, serving Greenwich, Lewisham, and the wider South East London area. She also offers online sessions.

Testimonials

Thank you so much. If it wasn’t for your questions about our children’s plans and your encouragement to ask the right questions, I wouldn’t have found out how unhelpful the school had been. It really helped us to move things along and make decisions, so a massive thank you from both of us.
