Jack Wallace

Director, BVM&S MRCVS


Jack set up Walnut Hill Equine Veterinary Clinic with Bridget Gatehouse in 2014 in his hometown of Henley in Arden. Jack’s grandfather Richard Wallace started a large animal practice only 3 miles from the clinic 60 years prior. Jack grew up on a farm in Henley in Arden, known as Walnut Hill which gave inspiration for the name for the practice - both Jack and his grandfather graduated from Edinburgh University.

Following graduation in 2008, Jack worked solely in equine practice. Firstly, in Inverness and Doncaster then at Spring Paddocks in Warwickshire, before starting Walnut Hill Equine Veterinary Clinic.

His main interest is in lameness investigation and optimising sport horse performance alongside carrying out a large proportion of pre-purchase examinations.

Jack trains and rides point to pointers from his home, training 3 winners so far. His other speedy companion is Billy the whippet, his sidekick out on the road and around the clinic.

We were lucky enough to have Lily join our team in 2018, focussing particularly on medical investigations, ophthalmology and routine ambulatory work. 

Lily has been involved with horses all her life. Last year she achieved her ambition of riding in point to points, and we are sure we'll see her out racing again soon!

Tammy finds that assisting in clinical duties and helping a busy practice run as smoothly as possible provides a variation of responsibilities to her role which makes it thoroughly enjoyable.

“We have a happy, small string of young horses in training, I love watching them develop and grow whilst doing all I can behind the scenes to help them on their way. At Walnut Hill we all muck in and gladly help each other when necessary. We make a great little team!”

Sally Wallace

Business Manager


Sally has been actively involved with Walnut Hill since the clinic was first set up by Bridget and her son Jack in 2014.

Being instrumental in the start up of the clinic, and overseeing various roles, from accounts to Sallys' current role as Business Manager (along with the overall running of the clinic), it’s fair to say Sally looks after everyone – staff and clients included.

Having successfully run Ardenforest Border Terriers for many years, Sally has lots of customer facing experience as well as a great business acumen, so is a key role in making sure the clinic runs smoothly and staff development is on-going.

Always a smiling face at the clinic you’ll no doubt see Sally with a cluster of border terriers at her feet!

"Walnut Hill has a wonderful team of vets and support staff to work with."
