About Sidonia Stiles
Sidonia Stiles (Sonia for short) is a UK-based counsellor who runs a private practice in Eastbourne. She specialises in relationship work, bereavement, anxiety, stress and depression, and brings wide experience supporting clients across the LGBT community and in one-to-one work. Sidonia blends a person-centred stance with relationship-focused therapies to help individuals and couples explore their histories, attachment patterns and the meaning they make from early family life.
Before training as a counsellor, Sidonia spent ten years working as a group worker for the local council, supporting residential young people and working with families through complex relational dynamics. That background informs her practical approach to family, parenting and blended-family concerns, as well as work with adoption, foster care and abandonment issues.
Sidonia is a registered counsellor with the BACP - the British Association for Counselling and Psychotherapy. Her formal training includes an HND Diploma (2006) in Person Centred counselling and a Level 5 Diploma in Relationship Therapy (2019) awarded by CPCAB - the Counselling and Psychotherapy Central Awarding Body. She uses clinical tools such as genograms when helpful and draws on Gestalt-informed ideas when supporting people through grief and loss.
Sidonia maintains a professional private practice offering evening and weekend appointments and, since the COVID-19 pandemic, also provides online sessions by video, phone, live chat and messaging. She accepts international clients and works with people facing a wide range of concerns including trauma and abuse, addictions, intimacy issues, self-esteem, career changes, caregiver stress and compassion fatigue.

Therapeutic Approaches and Online Support
Sidonia draws on several evidence-informed approaches to tailor therapy to each person's needs. Client-Centred Therapy focuses on creating a supportive, non-directive space where the client’s own goals and values guide the work - it is helpful for building self-esteem, managing life changes and processing emotional pain. Attachment-Based Therapy explores patterns formed in early relationships and how they influence current connections and intimacy - it can be particularly useful for relationship difficulties, abandonment concerns and family dynamics. Acceptance and Commitment Therapy (ACT) helps clients clarify personal values and develop psychological flexibility, offering practical tools for coping with anxiety, stress and ongoing life challenges.Finding the right approach is part of the therapeutic journey and Sidonia works collaboratively with each client to identify what fits best based on their needs, goals and preferences. She integrates techniques from different models as required so the plan evolves with the client's progress.
Online therapy options - including video calls, phone sessions, live chat and text-based messaging - make it easier to fit therapy into busy lives and to access support from different locations. These formats provide flexibility in scheduling and the ability to maintain continuity of care, allowing clients and licensed professionals to work together in ways that suit practical and emotional needs.
