About Sidonia Stiles
Sidonia Stiles (Sonia for short) practices from the The Natural Fitnesses Centre in Eastbourne, where she offers person-centred and relationship-focused therapy informed by decades of experience. She specialises in relationship difficulties, bereavement, anxiety, stress and depression, and has worked closely with members of the LGBT community in both relationship and one-to-one settings. Before training as a counsellor she spent ten years as a group worker for the local council supporting residential young people and working with families through complex relational dynamics.
Sidonia is a registered counsellor with the BACP, and she trained formally with an HND Diploma in Person Centred Counselling (2006) - a Higher National Diploma - followed by a Level 5 Diploma in Relationship Therapy (2019) awarded by CPCAB (Counselling and Psychotherapy Central Awarding Body). Her clinical work often explores the impact of upbringing and family systems on present-day relationships, and she uses tools such as genograms to map family patterns and meanings.
She also works with bereavement using an understanding of Gestalt ideas about loss and how people make sense of grief, aiming to respect each person's unique experience. Sidonia runs a private practice in Eastbourne most evenings from 6-8pm and at weekends, and since the COVID-19 pandemic she has been offering online sessions to increase access and flexibility for clients.

Therapeutic Approaches and Online Support
Sidonia draws on client-centred therapy, which focuses on creating a respectful, non-directive space where people are supported to explore their own feelings and choices - this approach is helpful for building self-understanding, improving self-esteem and navigating life changes. She also uses attachment-based therapy to examine how early relationships shape current patterns of relating; this work can be especially useful for couples, those coping with abandonment or attachment-related difficulties, and people wanting deeper insight into their relational habits. Acceptance and Commitment Therapy (ACT) is another approach Sidonia employs to help clients notice difficult thoughts and feelings while identifying values-driven action - ACT can support coping with anxiety, stress and ongoing life challenges.
Finding the right approach is part of the therapeutic journey. Sidonia works collaboratively with each person to identify which methods best fit their needs, goals and preferences, and she adapts techniques as the work evolves to ensure therapy remains relevant and helpful.
Online sessions are offered by video call, phone, live chat or text-based messaging to provide flexibility and accessibility for different schedules and needs. These options make it easier to attend regular sessions, maintain continuity during life transitions, and access support from wherever a client is located while working with licensed professionals and experienced therapists.
