I have been a Consultant Dermatologist for 20 years and I am trained and active in all areas of dermatological practice. I have been treating patients with skin disease for 25 years, becoming one of the most experienced dermatologists in the area. I run a well-established medical dermatology practice based here at the Spire Leicester Hospital which is managed by my Personal Assistant Mrs Debbie Keast. This provides an accessible, friendly and efficient service to patients with a wide variety of skin problems.

I am the President of the British Society for Cutaneous and an expert in the investigation and treatment of dermatitis and eczema and receive patient referrals from General Practitioners and consultant colleagues across the region, from legal firms across the country and cosmetics companies across Europe. I am lead author for the current British Association of Dermatologists’ Guidelines for the Management of Contact Dermatitis.

I undertake patch testing for the investigation of contact dermatitis both for patients with allergies to personal products and those with occupational disease. I am also fully trained and experienced in the treatment of skin lesions and skin cancer. I offer dermoscopy for suspected skin cancer and run a weekly minor surgical service. I also offer a cryotherapy service for the treatment of minor or premalignant skin lumps and bumps.

While I do not undertake cosmetic dermatology, I perform over 100 minor surgical procedures a year at the Spire Leicester Hospital. These range from symptomatic minor skin lesions and cysts to removal of skin cancer. I also perform over 500 cryosurgical procedures every year for pre cancerous skin lesions and sun damage.

In addition to my full time clinical work, I am an Honorary Senior Lecturer at the University of Leicester and I am the Clinical Lead in a £2.4million Medical Research Council funded study of a new scar treatment. I am Principle Investigator on several national studies into new treatment of skin disease. I was a systematic reviewer for a major study by the British Occupational Health Research Foundation Working Group on Occupational Contact Dermatitis and Urticaria 2010. I was Clinical Expert for the National Institute for Clinical Excellence (NICE) in 2009 to advise on a new tablet, alitretinoin, for severe eczema.

I lecture on national courses including the British Contact Dermatitis Course (100% attendees rated my lectures good/excellent), the BAD Clinical Assistant course and the Diploma course for the Royal Society for Public Health. I have published chapters in several major medical textbooks including The Skin and the Gastrointestinal Tract for the seminal dermatology textbook Fitzpatrick’s Dermatology in General Medicine. I have published over 150 papers and abstracts in prestigious medical journals on the diagnosis and treatment of skin diseases. On television and in the press I regularly advise on medical problems such as skin cancer and allergy.

I have received the following Awards: Medical Research Council Wound Healing Grant in 2015, UK Clinical Research Network funding in 2009, The British Skin Foundation Small Grant Award in 2005, The British Association of Dermatologists Travel Fellowship and The Royal Society of Medicine Wallace Essay Prize in 2000 and The Sanofi-Winthrop Foundation Small Grants Award on 1997.

I enjoy all things Italian including food, wine and art. I speak Italian badly in an attempt to continue the above when on holiday. I enjoy skiing, am a classically trained violinist in a local orchestra and play the piano when my family allow me!
