In 2017, Alfonso moved to the UK, where he completed a specialized internship at the University of Liverpool, followed by a 3-year Residency programme in Anaesthesia and Analgesia alongside a Masters course (MVetMed) at the Royal Veterinary College, London.

Alfonso joined Highcroft Referrals in 2021. He enjoys all aspects of his discipline but shows a special interest in mechanical ventilation, anaesthetic management of the critically ill patient and locoregional anaesthesia.
