Lead Veterinary Surgeon, Marylebone 

Providing a highly bespoke and empathetic service, Allison goes above and beyond in the clinic and during home visits. Lauded as “the vet to celebrities,” she is trusted by A-listers and VIPs who require prompt, sophisticated, and discreet care, often involving private international pet travel. She studied at The Royal Veterinary College and holds multiple degrees alongside her OV (Official Veterinarian) and MRCVS status. Her expertise spans complex pet import/export services, soft tissue surgery, outpatient management, and small exotic species. 

An animal lover from a young age, Allison is originally from outside Boston, Massachusetts, and dreamed of becoming a vet while growing up. Today, she is recognised for her compassionate, patient-first, and personable approach, going above and beyond in every consultation. Allison lives in Belsize Park with her cat Benjamin and enjoys theatre and poker in her free time. 

“Pets bring unconditional love into our lives, and I can’t think of a greater use of my time, energy, and skills than to honour and preserve that.”
