Qualifications

MSc, Transdisciplinary Practice — Middlesex University.

My dissertation examined how nutrition may be used as a complementary tool for chronic eczema and dermatitis support, which is the exact question this practice is built around.

DipIoN — Diploma from the Institute for Optimum Nutrition

One of the UK's established nutritional therapy training providers.

I retrained as a Registered Nutritional Therapist after nutritional therapy changed my own eczema, having lived with it since I was six months old. I wanted to understand the science properly, not just what had worked for me, but why, and how to apply it reliably for other people.

Professional Registrations

  • mBANT — Member of the British Association for Nutrition and Lifestyle Medicine, the professional body for registered nutritional therapists in the UK.
  • CNHC — Registered with the Complementary and Natural Healthcare Council, the UK regulator holding the government-approved register for the profession.
  • Director of BANT — I serve on the board of BANT, contributing to the standards and direction of the profession.
  • Member, British Society for Integrative Oncology (BSIO) — the UK professional society for practitioners working in integrative cancer care.

Being CNHC-registered means I work to a set standard of training, ethics, and professional conduct. You can confirm my registration on both registers directly (links below).

SPECIALIST ACCREDITATIONS

  • Oncology and nutrigenomics — listed on the BANT register. I'm on the BANT register to practise in oncology, nutrition support for clients who have eczema alongside a cancer diagnosis or a history of cancer, and in nutrigenomics, the study of how your genetic variants influence the way your body processes nutrients.
  • Eating Disorder Support — specialist training in progress. This will be available as a dedicated service shortly, for clients whose eczema is entangled with a difficult relationship with food.

CLINICAL ROLES

Alongside my own practice, I'm the nutritional therapist at Mosaic Medical, a doctor-led integrative clinic, and the only one on their team. I see their patients across a wide range of conditions, including the clinic's breast cancer service, working alongside their doctors and specialists.

It's the same principle I bring to every client, nutritional therapy as part of the team around you, not apart from it.

As heard on

The Mosaic Medical podcast — Piecing Together the Fragments of Your Health Episode 2: Personalised Nutrition & Nutrigenomics.

I join host Dr Camilla Stokholm to talk through nutrigenomic testing, the cheek-swab DNA test that shows how your genes influence everything from histamine clearance to hormone pathways and nutrient absorption, and how we use it within Mosaic's Breast Cancer Service.
