Anaesthesia and Analgesia team

Alessandra Mathis


Head of Anaesthesia
RCVS Specialist in Veterinary Anaesthesia
European Specialist in Veterinary Anaesthesia and Analgesia

Alessandra graduated from the University of Perugia (Italy) in 2003, after which she worked in general veterinary practice in Italy for three years. During this period Alessandra really enjoyed the challenge of facing a variety of cases every day, but soon became keen on Anaesthesia and felt that she wanted to specialise in the subject.

Alessandra decided to visit Anaesthesia departments in a number of veterinary institutions, mostly in North America. Alessandra then undertook an Anaesthesia Internship at the Royal Veterinary College in London followed by a three year Residency in Anaesthesia and Analgesia at the Royal Veterinary College during which she gained her RCVS Certificate in Veterinary Anaesthesia.  Alessandra then joined Willows in 2011 and became a Diplomate of the European College of Anaesthesia and Analgesia in 2012.

Alessandra is particularly interested in the anaesthesia of the critically ill patient and in pain management. She enjoys working as part of the team of highly qualified and dedicated specialists at Willows, and helping to keep the veterinary and clinical support staff up to date with the latest anaesthetic and intensive care techniques.

Alessandra is the daughter of a dog breeder and a diplomat. She grew up mostly in Italy, but also lived in Australia and Switzerland and always with several dogs and cats. She particularly loves Dachshunds and had one named Olga, who she loved dearly for her fifteen years of life and who accompanied her through most of her life’s challenges. Alessandra’s love for Dachshunds blossomed further when she brought home Sheldon who loves to run in the woods, mostly if he is running after a squirrel (which he never catches!). Although Alessandra misses the Italian sun and food, her family and Italian friends, she feels as though she has gained a second family at Willows!


Alastair Mair


European Specialist in Veterinary Anaesthesia and Analgesia

Alastair graduated from the University of Edinburgh in 2001. He initially spent two years in mixed practice in Scotland before undertaking a general internship at a private referral hospital in southern England. This lead to an internship in anaesthesia at the University of Bristol, followed by a residency at the University of Glasgow.

Alastair moved to the University Veterinary Teaching Hospital in Sydney, Australia in April 2012 where he was employed as registrar in veterinary anaesthesia, progressing to Head of Department. He holds the RCVS Certificate in Veterinary Anaesthesia and is a Diplomate of the European College of Veterinary Anaesthesia and Analgesia (ECVAA).

Alastair is interested in all aspects of veterinary anaesthesia, especially pulse CO-oximetry and anaesthetic record keeping. Outside work Alastair’s hobbies include learning to play the bagpipes and to speak mandarin Chinese.


Jacques Ferreira


RCVS Specialist in Veterinary Anaesthesia and Analgesia
European Specialist in Veterinary Anaesthesia and Analgesia
South African Specialist in Veterinary Anaesthesia and Analgesia

Jacques graduated from the University of Pretoria with a Bachelor of Science (Biotechnology) in 2006, directly after which he enrolled in a Bachelor of Veterinary Science, which he completed in 2011. Jacques always had an interest in physiology and pharmacology and after completing a 12 month rotating internship in Small Animal Medicine and Surgery at the Onderstepoort Veterinary Academic Hospital, he went back to the University of Pretoria where he enrolled in a Veterinary Anaesthesia and Analgesia residency and Masters of Science simultaneously.

Jacques’ MSc investigated the effect of various anaesthetic drugs on the quality of anaesthesia induction and recovery. After three years of very diverse work anaesthetising a range of animals including rhinos, elephants, lions and even a seal, Jacques moved to the United Kingdom in 2015. Jacques spent two years as a lecturer in Veterinary Anaesthesia at the University of Liverpool and in 2017 became a Diplomate of the European College of Veterinary Anaesthesia and analgesia. Currently, Jacques has a particular interest in peri-operative pain management, focussing on the use of local anaesthetic techniques for prevention of nociception.

When not at work, Jacques is a keen triathlete and squash player and can often be found running trails in Wales, with his running partner Murdoch, a 3-year-old German Shepherd dog.


Anna Bryla


Veterinary Anaesthesia and Analgesia
MSc in the Clinical Management of Pain

After qualifying from the University of Warsaw in 2003, Anna worked for two and a half years as a veterinary advisor for Kolme, a large pharmaceutical company in Poland. This position enabled her to develop her knowledge in pharmacology and homotoxicology. During this time Anna attended a Management Educational Centre where she completed a one year course in law. In her spare time she worked as a volunteer at an Animal Rescue Centre.

Anna’s vocation has always been to work with small animals and to this end she decided to seek a position in a practice where she could pursue her goals.  In 2007 she joined the team at Willows, where she developed her skills in anaesthesia, critical care and pain management. In 2014 Anna gained her MSc (Master of Science) in the Clinical Management of Pain at the University of Edinburgh. Anna’s key area of interest is the provision of anaesthesia and analgesia for challenging surgical patients.

Outside the practice Anna is a theatre and opera lover. She attends ballet classes and can play both the piano and the guitar. Anna is the owner of two show dogs – an Akita and an Afghan Hound – and she is interested in becoming a dog show judge.
