About Me

My name is Sian Leone Williams.

I am an MBACP (Registered member of the British Association for Counselling and Psychotherapy) Accredited counsellor / psychotherapist. I have been in professional practice since 2004. I have also provided supervision for counsellors / psychotherapies and supportive supervision for those working in front line services to manage their psychological well-being in often pressurised roles with potential for experiencing trauma within their work role for over 14 years.

As part of my commitment to my profession and to maintain my accreditation within the BACP (British Association for Counselling and Psychotherapy) I undertake monthly supervision to ensure my safe practice. This is undertaken by a Clinical Psychologist from whom a reference can be provided if required. I also continue to develop my skills and remain up to date by undertaking regular CPD (Continuing Professional Development).


I have worked as a counsellor / psychotherapist for over seventeen years and have maintained a private practice for over fourteen years. Within my private practice referrals come from private individuals, recommendations, GPs, health care providers, employers, insurance companies and EAPs (Employee Assistance Programmes).

For over ten years I worked for a staff support and psychological well-being service for a mental health NHS Trust and held the role of Clinical Lead responsible for a team of eighteen. I ensured provision of psychological support for employees within our own Trust as well as those within other NHS Trusts, areas of the public sector, financial services and industry for which we held contracts. I liaised directly with Occupational Health, Human Resources and Trades Unions to develop clinical pathways for mental health to support employee well-being and to reduce sickness absence and ‘presenteeism’ in the workforce.

Throughout this period I maintained my own clinical caseload and supported teams where a ‘traumatic event’ had occurred. I also provided supervision to other clinicians from trainees to experienced counsellors / psychotherapists as well as ‘supportive’ supervision to members of front line services teams who were regularly confronted by potentially distressing events as part of their daily work.

I have provided training for counsellors and therapists and for GP surgeries on topics such as ‘ Importance of boundaries within workplace counselling’, ‘Working with anxiety’, ‘Working with depression’, ‘Using Outcome Measures Effectively’ etc.

Whilst working in the NHS, as a qualified mediator, I also provided mediation within the workplace – I no longer practice directly as a mediator but have found these skills invaluable in working with clients who struggle with workplace relationships.
