Meet Our Superintendent Pharmacist Neil Gathani

Our programme uses licensed GLP-1 treatments alongside blood testing, metabolic tracking and nutritional review, so your progress is measurable from day one.

About Dr Mariana Dumitriu
I’m Dr Mariana Dumitriu, a GP with a special interest in weight management and disability medicine, practising since 1999. Over the years I’ve developed a particular passion for helping people achieve sustainable, healthy weight loss – combining medical expertise with practical, realistic support tailored to each patient’s needs and goals.
As part of this, I offer medically supervised weight loss treatment using GLP-1 medications such as Mounjaro (tirzepatide), prescribed safely and appropriately following full clinical assessment. I take a compassionate, evidence-based approach, giving patients the guidance and confidence they need to feel healthier and more like themselves.

Why Dr (h.c.) Marva Williams
The majority of our patients are women in midlife, many navigating perimenopause or menopause a stage where hormonal shifts can make weight loss significantly more difficult, regardless of diet or exercise. Marva’s specialism directly addresses this gap in care.
Clinical relevance – Symptoms such as disrupted sleep, brain fog and anxiety commonly affect adherence and consistency during a weight loss programme. Addressing these alongside treatment supports better outcomes.
Complementary expertise – Our clinic manages the medical and metabolic side of weight loss; Marva’s coaching addresses the hormonal and psychological factors that often accompany it.
Together, this offers patients more complete, joined-up support.
Credibility and profile – As a recognised voice in menopause health, with national media coverage including BBC and ITV, Marva brings additional trust and authority to the partnership.
Shared patient demographic – Her focus on midlife women’s health aligns closely with our own patient base, making referrals and collaboration a natural fit.
