Gayle's supervision is grounded in warmth, trust and transparency. Her aim is to create a space where you feel able to bring your client work openly — supported yet appropriately challenged to grow as a practitioner in your own right.
Having benefited from excellent supervision throughout her own career, Gayle understands its value deeply and brings that understanding to every supervisory relationship.

Stoltenberg & Delworth (2002) — supporting each supervisee's individual stage of professional development.
Informed by psychodynamic concepts, with a focus on the therapeutic relationship and reflective practice.
I always feel seen, validated and supported in our supervision sessions. Gayle always has great insights and encourages me to look at other angles — she has such a broad knowledge base.
To have someone with so much warmth and compassion, mixed with knowledge and experience, was pivotal in my development from trainee to qualified counsellor.
Gayle has taken me through my supervision with invaluable care, compassion and expertise in equal measure. She always offers the perfect balance of guidance and self-exploration.
Supervision has felt collaborative, and I have always felt able to bring both challenges and successes to explore and celebrate. Gayle's warm, empathic approach has been invaluable.
I look forward to my supervision sessions with Gayle. She allows me to speak freely and offers advice without judgement. Her wealth of knowledge means she can offer suggestions to support my work.
Gayle is caring yet professional and challenging yet accepting. I am thankful for the CPD suggestions she signposted me to and the discussions of theory relating to my work.
