The London Vet Clinic is more than a primary care veterinary clinic. Uniquely, we provide, on-site, a variety of second opinion skills including cardiology, internal medicine, ophthalmology, advanced dentistry, advanced endoscopy and day patient soft tissue, orthopaedic and minimally invasive surgery. We are, we think, the only primary care vet clinic in the UK providing behaviour counselling from a vet with post graduate qualifications in clinical animal behaviour.

Augmenting the staff of the London Vet Clinic is a diverse and highly skilled group of referral experts and specialists at our colleagues at The Ralph, in Marlow. These men and women routinely provide continuing education to the veterinary profession, and are sought after lecturers at regional, national, and international veterinary meetings, symposia and conferences. The Ralph is our preferred referral partner because they are in harmony with our ethical attitude, that we always consider what an animal might want done if it had the chance to participate in decision-making.

Dr Natalia Aira Bewick 

Natalia has been helping people with their pet’s behaviour concerns in London and North Wales for the past few years. She has always been passionate about behaviour and has studied how early experiences in puppies influence personality traits in adult dogs.

What Natalia finds most rewarding when working with dogs and cats with behavioural problems is helping pets and their people understand each other and build a strong bond. Natalia is available at the London Vet Clinic for referred cats and dogs with any type of behaviour issue.

James Creasey 

The most common, sudden joint injury that dogs experience is a torn anterior cruciate ligament. James is one of the country’s most experienced veterinary surgeons using the ‘Tibial Plateau Levelling Osteotomy (TPLO) procedure to repair torn cruciates in dogs’ knees. He performs around 700 cruciate repairs each year and has been doing so for over 10 years.

James is equally proficient repairing slipping kneecaps, especially in small individuals and using an arthroscope to examine and repair painful elbow conditions, not uncommon in Labradors and similar size dogs.

James studied at Bristol University’s vet school when Stephen Warren was there, graduating in 2003. At York Street we have the facilities for James to carry out repairs ensuring that virtually all the dogs he operates on are back in their own homes the same day.


David Williams 

David runs Cambridge vet school’s ophthalmology clinic, where his special interests are cataracts and eye immunology. He has decades of experience treating eye conditions in dogs and cats and understands that less intervention is often in our animal companions’ best interest. In that context its not surprising that David also runs an ethics course for Cambridge’s vet students.

David studied at Cambridge University’s vet school when Grant Petrie was there, graduating in 1988. Both did their post graduate training at the Royal Veterinary College. David moved on to the Animal Health Trust’s renowned ophthalmology unit but when that organisation ceased to exist he returned to Cambridge. At York Street we have the facilities for David to carry out eye examinations and repairs ensuring that all the animal companions he sees are back in their own homes the same day.

  • David has over 230 publications in veterinary ophthalmology and animal welfare
