Marios Charalambous DVM PGC PGD PhD DipACVIM (Neurology) DipECVN FHEA MRCVS Neurologist

Board Certified Specialist and Referral Consultant Neurologist

Marios graduated from Aristotle University of Thessaloniki, Greece in 2010.

He worked within academia and private practice in Greece and the UK before undertaking a residency at Cornell University, and a further residency at Ghent University before becoming a Diplomate of ACVIM and ECVN.

His clinical are all aspects of neurology and neurosurgery, with particular interest in epilepsy and seizure emergencies.

Marios says, “I find neurology one of the most challenging specialities in veterinary medicine. In addition, since many vets experience neurophobia, my aim was to explore and enhance further this field.”

In his spare time, Marios likes to spend time with friends and family, and also enjoys hiking, exercising and cooking. He also shares his life with his 2 cats, Pablo and Kyuubi – both are orange, naughty and sweet!
