About Sidonia Stiles
Sidonia Stiles, often called Sonia, maintains a therapy practice at the Natural Fitnesses Centre in Eastbourne, United Kingdom. She works from a person-centred foundation and combines relationship-focused psychodynamic perspectives to support individuals and couples navigating difficult life experiences. Her practice concentrates on relationship concerns, bereavement, anxiety, stress and depression, and she has specific experience supporting LGBT clients in both one-to-one and relationship work.
Before training as a counsellor, Sidonia spent ten years as a group worker for the local council supporting residential young people and working with families through challenging relationship dynamics. That background informs her interest in family systems, upbringing and the ways early experiences shape current conflicts and attachments. She uses clinical tools such as genograms to explore family patterns and histories.
Sidonia is a registered counsellor with the BACP and holds an HND Diploma in Person-Centred Counselling (2006) and a Level 5 Diploma in Relationship Therapy (2019) awarded by CPCAB (Counselling & Psychotherapy Central Awarding Body). She also draws on Gestalt ideas when working with grief, respecting each person’s unique response to loss. Sidonia runs a private practice in Eastbourne most evenings and at weekends, and she began offering online sessions in response to COVID-19 to increase access to her work.

Therapeutic Approaches for Online Support
Sidonia draws on Client-Centred Therapy, Attachment-Based Therapy and Acceptance and Commitment Therapy (ACT) to shape her online work. Client-Centred Therapy focuses on creating a respectful, non-directive space where the person is supported to find their own solutions; it is helpful for people working on self-esteem, life transitions and relationship challenges. Attachment-Based Therapy explores early relationship patterns and how they influence current connections, which can be particularly useful for those struggling with intimacy, abandonment or family dynamics. ACT emphasises accepting internal experiences while committing to values-driven action, and it can support people managing anxiety, depression and ongoing stress.
Finding the right approach is part of the therapeutic process and Sidonia works collaboratively with each client to determine which methods best match their needs, goals and preferences. She tailors the work over time, combining techniques where appropriate to address the presenting issues.
Online therapy with Sidonia is offered via video calls, phone sessions, live chat and text-based messaging, providing flexibility for different schedules and comfort levels. These options make it easier to access regular sessions from home or while travelling and allow the therapeutic relationship to continue even when in-person meetings are not possible.
