Bruce Middleton MA VetMB MRCVS (Partner)

After graduating from the University of Cambridge Bruce started work in Wendover before moving to Haslemere to work for an equine practice in Sussex. Setting up his own equine practice in 2003 near the borders of Surrey, Hampshire and Sussex, Bruce was joined by John Hennessy the following year and has grown the practice from humble beginnings to a highly successful but still very personalised equine veterinary clinic. Leading the sport horse side of the practice Bruce has worked with many high-class showjumpers, eventers and dressage horses as well as being intimately involved with the success of many high-goal polo teams over the years, yet still enjoys general equine practice.
Bruce is married with 3 children and away from work he enjoys skiing and travelling with his family, mountain biking and is the chairman of the Haslemere RUFC Juniors as well as a coach.

He is now one of the most experienced vets in the UK in the field of equine reproduction. Between the seemingly endless amounts of mares to get in foal each summer around Surrey, Hampshire, East Sussex and West Sussex, John has a special interest in eventing and showjumping providing veterinary care from for many world class equestrian athletes.
John is married with two children, and when the breeding season calms down he enjoys spending time at home in the garden.
