The Willow Veterinary Clinic is owned by Mr Alan Johnston B.V.M.S., M.R.C.V.S. and Mr Mark Seager M.V.B., M.R.C.V.S.

Alan and Mark established The Willow Veterinary Clinic in Portadown on Easter Monday in 2000. Both Alan and Mark had a number of years’ experience in large and small practices within the area and were well known.

Alan and Mark purchased a private 3 bedroom bungalow and converted it into veterinary clinic. As clients and staff increased in size the practice outgrew itself. They began the renovation of their purpose-built premises in Spring 2010 and it was completed in Summer 2011.
