Phone: 07909 517187

I qualified from Glasgow Vet School in 1989 and after working for ten years in England and three years in New Zealand I settled in Shropshire in 2002 working for Abbey Vet Centre before starting Macpherson O’Sullivan LLP with Tim in 2003. This has progressed on to Shropshire Farm Vets Ltd of which I am now Managing Director. I am married to Jane and have two children, George and Isla. When I get some time, on a clear night I can be found in a roofless shed with a couple of telescopes taking pictures of galaxies/nebulae. Otherwise I am known to chase deer in Scotland and take the odd photograph.

I qualified as a vet from Dublin in 1994 and have been a full time farm vet since 1997. Together with Alistair we established Macpherson O’Sullivan Farm Vets in 2003 to better serve Shropshire farmers, with a specialist farm veterinary service. This has since progressed into Shropshire Farm Vets.  As a practice we have always tried to educate and inform our clients as much as possible and I am one of several Lantra accredited trainers in the practice. I organise and run DIY AI training, calf health training and dairy cow nutrition training days on a regular basis.

Graduated Ghent, Belgium 1996. I worked in mixed practices in Four Crosses, Carmarthen and Montgomery before seeing the light in 2004 and focusing on farm animals only. My interests are Bovine surgery and cattle lameness. I get a lot of satisfaction out of making lame cows better and training clients the correct 5 step foot trim. As a practice we regularly organise foot trimming courses and provide training days. Recently I became a Mobility Mentor with DairyCo. I’m also passionate about fertility and preventative medicine in sheep.

I graduated from Bristol in 2006 and spent a year in mixed practice in rural Berkshire. During this time, I decided to pursue a career in a farm animal veterinary practice, and joined the team at Mac&O in 2007 which has now progressed to Shropshire Farm Vets. Improving animal health and welfare, whilst enhancing overall farm profitability through good health and fertility management are aspects of my job which I enjoy most.

Phone: 07522 637322

I graduated from University of Santiago de Compostela in 2006. I spent the following 2 and a half years working for a farm animal practice in Salamanca, working with beef, sheep, pigs and typical Spanish bulls. I then worked as a TB tester in two different areas of Spain. After 15 months “relaxing” at home due to injury I needed a risky but exciting change in my life (the “now or never” challenge sometimes you feel you need at some point in life…) so I headed to British landm first as a meat inspector in slaughterhouses around the country and now here at Shropshire Farm Vets. In my free time i like going out with friends, sport, and travel.

I graduated from the University of Cordoba in Spain. After several internships at mixed practices within Spain, I decided to explore new adventures and headed to the UK. Firstly, I worked as a Veterinary meat hygiene inspector but I have always been interested in working with farm animals, so when the opportunity arrived I didn’t hesitate to take it and joined Shropshire Farm Vets in April 2015.
In my spare time I enjoy reading and playing tennis.

Phone: 07874 054328

After graduating from the University of Giessen in 2012, I went on to face different challenges. The first one was moving to the UK to live with an English family and improve my English. During this time, I volunteered at a wildlife rescue centre and RSPCA clinic which have been great experiences. After a year, I felt it was time for the next step moving from Essex to Lincoln where I worked as a Veterinary meat hygiene inspector in slaughterhouses, which is what I did until I joined SFV in May 2015. Outside of work I enjoy spoiling my friends and colleagues with homemade cakes and my cat with lots of cuddles.


Mihail Stoica MRCVS – TB Testing Vet


I qualified as a vet from Bucharest in 2014 and after working for two years in the rural side of Romania, I moved to the UK. Since “the big move” I worked as a Veterinary Meat Hygiene Inspector until October 2017 when I joined Shropshire Farm Vets, bringing me closer to my passion which is working with farm animals. Outside of work I enjoy fishing, cooking traditional Romanian food for my friends and traveling.

Siobhan Harrington-Hayes

Siobhan Harrington-Hayes – Receptionist

I moved to Shropshire and joined Shropshire Farm Vets in June 2017. I have a range of experience in reception, customer service and stock specialist roles. These skills have come in handy as my time in the practice is mainly split between Reception and Pharmacy. Amongst other things I am also becoming more involved in some of the practice health and safety and fleet coordination aspects.
Most of my spare time up until recently has been home DIY based but I am now looking forward to getting out and about on my bicycle and exploring Shropshire.
