Dr. Stewart’s cats, Mabel and Jackie

Dr. Heather Stewart

Originally from Montreal, Dr. Stewart earned her undergraduate degree in Microbiology and Immunology with Honours from McGill University. She was one of six Anglophones out of a class of seventy to attend the University of Montreal in Veterinary Medicine, a program given entirely in French. She finished second in her class and worked at the University every summer. She applied and was accepted as an intern at the Ontario Veterinary College in Guelph. She spent a year in the Small Animal Program where she supervised students, worked on cases and learned new skills and techniques in Small Animal Medicine and Surgery. She worked for eight years in small animal practice and surgery; it was during this time that she realized her true love for cats. She saw how different cats were from dogs and realized they needed a specialized level of care. She started her feline-only practice in 1988 so that should could provide felines with the individual care they need. Dr. Stewart says, “I find that feline medicine is individual to each cat, and is part science, part detective work and part art”. She also attends over thirty hours of Feline Continuing Education Lectures annually to stay on top of the latest treatments for her patients. When she’s not at the clinic Dr. Stewart shares her loft with two cats, Jack Sparrow and Mable, both of which she acquired through Guildcrest Cat Hospital’s Buddy’s Buddies program. They both take their job of making Dr. Stewart happy very seriously. When she’s not at home, Dr. Stewart enjoys golfing, skiing and travel and stays fit through Pilates.

Dr. Julia Hammond

Dr. Julia Hammond is a 1991 graduate of the Atlantic Veterinary College in Charlottetown, Prince Edward Island. After moving to Ontario, she spent time working at many practices across the province as a locum. Dr. Hammond joined Guildcrest in 2016 and we couldn’t be happier. Her energy and compassion make her an excellent Veterinarian and addition to our team. Dr. Hammond lives with her family and her two cats, Dave, and Daisy. Dave enjoys hunting for small animals, terrorizing Daisy, and escaping out the front door. Daisy enjoys cuddling, napping and spends much of her day avoiding Dave. In her free time Dr. Hammond enjoys reading, travelling, and spending time with her family. She belongs to Trinity Sopranos, a classical singing ensemble.


Arima joined Guildcrest Cat Hospital in 2011 and has a deep love for all animals. As our Receptionist, she is perfectly suited for the job and loves interacting with our clients and their cat. Arima is well versed in all aspects of the clinic, but can often be found behind the front desk greeting clients with her bright and beautiful smile! She lives in Scarborough with her family, her cat Cheddar, and her two dogs; Sandy and Kiwi. When Arima is not in the clinic, she enjoys spending time with family and friends, adventuring with her dogs or spending a chill night in.


Shannon is our manager and began working with Guildcrest Cat Hospital in 2010. She has been in the animal care field for over 9 years and is excited to continue her journey. Shannon can be found all over the clinic; from technician to reception, and never stays in one place for too long. Shannon lives in Scarborough and has 2 cats, Twitter and Mia and a dog named Storm. During her free time, she enjoys adventuring with Storm, riding her motorcycle, weekends up north and spending time with family and friends.


Simon says… you do. Simon has been with us since he was for about 5 years now. A client had brought Simon in with urinary tract issues and crystals. After along hospital stay including surgery, the owners opted to surrender him to us due to his ongoing medical issues. Simon has since recovered from his illness, although is still quite prone to infections. Simon’s life must be managed very carefully due to his condition; therefore, we have decided to keep him as a clinic cat. Simon is adorable, super friendly and loves to cuddle. He greets each client as they come in while sitting on top of the reception desk, demanding attention, and making it difficult to process transactions, because petting him is much more important. When Simon (finally) decides to take a break, he’s found a human shoulder to nap on, or he’s rolling around on the floor in the sun.
