Dr. Lily Loo
Owner, Veterinarian
Growing up in Montreal and Toronto, Dr. Lily Loo spent a lot of time with her first cat, Taffy. Taffy needed specialized dental care after only a year of age, and Dr. Loo was happy to oblige. She brushed her feline friend’s teeth every day, and even ended up taking Taffy to see a few dental experts. These early experiences in animal care sparked Dr. Loo’s interest in veterinary medicine, and her passion never wavered. Now, she’s a full-time veterinarian and the owner of Markham Veterinary Clinic!
Dr. Loo attended Ontario Veterinary College at the University of Guelph to receive her degree in veterinary medicine. She graduated in 1997, and joined the Markham Veterinary Clinic team shortly afterward. After working full-time here for nearly 17 years, Dr. Loo purchased the practice in December of 2014.
Dr. Cathy Leung
Associate Veterinarian
Dr. Cathy Leung’s parents grew up without pets, and they weren’t always keen on the idea of getting animal companions for their children. After many years of persistent nagging, Dr. Leung and her sister finally wore their parents down! That’s when they brought home the first family dog, Winter. Dr. Leung’s life was forever changed—ever since, she’s wanted to help others’ pets lead happy, healthy lives.
Dr. Leung’s first introduction to the world of animal care came during high school, when she began shadowing her family’s local veterinarian. Next, she started volunteering at another nearby pet clinic, working her way through the ranks as a Veterinary Assistant, receptionist, and even a Veterinary Technician. Dr. Leung studied veterinary medicine in Guelph to become a licensed veterinarian, then returned to her hometown of Markham to begin her professional career. Now, she’s an Associate Veterinarian here at the hospital!
Dr. Sonya Firth
Associate Veterinarian
Dr. Sonya Firth cannot remember a time in her life when she didn’t want to become a veterinarian. She’s always had an affinity for the earth’s creatures, and caring for those in need simply made her happy. Dr. Firth is also fond of logical problem solving and has a keen interest in science—by working as a veterinarian, she’s able to combine her passion for biology and her adoration of animals in one fulfilling career!
Dr. Firth grew up in North York, Ontario as the middle of three children, and was constantly surrounded by wildlife thanks to the ravine located near her family’s home. As a teenager, she began working at a pet store and various animal clinics to gain invaluable experience—she would even ride along with large-animal veterinarians to learn as much as she could! Dr. Firth enrolled in the biological sciences program at the University of Guelph, then continued on to receive her Doctorate of Veterinary Medicine there. She moved to the Markham area shortly after graduating in 1988, then joined the Markham Veterinary Clinic family in the spring of 1989.
Dr. Irene Lui
Associate Veterinarian
Ever since she can remember, Dr. Irene Lui was interested in science and problem-solving. Like most veterinary professionals, she also adored animals of every shape and size. For her, putting her passion to good use by helping pets on a daily basis is a dream come true! Dr. Lui is a proud member of Markham Veterinary Clinic’s talented team of Associate Veterinarians.
Dr. Lui is a Markham native and was only in high school when she began volunteering at local animal clinics and shelters. (In fact, she spent time volunteering and shadowing vets right here at Markham Veterinary Clinic!) Dr. Lui continued on to study veterinary medicine at The University of Guelph’s Ontario Veterinary College, becoming a licensed veterinarian after graduation, then returned to her hometown to launch her career in private practice. It wasn’t long before she became a member of the Markham Veterinary Clinic family once again, and she’s been helping the area’s pets and animal parents ever since!
Dr. Beverly Wong
Locum Veterinarian
Dr. Beverly Wong spent a good deal of her childhood at the Toronto Zoo—she would stand out in the sun, rain, or snow just to watch the tigers sleep! As her passion for biology and physiology blossomed while she progressed through school, one thing became clear: a career in veterinary medicine was the perfect choice for Dr. Wong.
A Markham native, Dr. Wong started volunteering at local animal shelters while still in high school. She was hired as a receptionist and kennel staff member by a local veterinary clinic as she started her undergraduate studies at Queen’s University, and even spent a summer as an animal attendant for the African Lion Safari during this time. Dr. Wong was then accepted to Ontario Veterinary College to receive her veterinary degree.
Dr. Patricia Khor
Locum Veterinarian
Dr. Patricia Khor developed her love for animals very early in life. As a little girl, she grew up helping out at her aunt’s pet store. For her high school co-op placement program, she chose to work in a veterinary clinic. It was then that she realized that she had found her calling; to use her passion for animals and love of medicine to better the lives of pets and their owners!
After high school, she attended the University of Guelph and was accepted into the Ontario Veterinary College, graduating with her veterinary degree in 2002. At graduation, she was recipient of the Beloved Friends Award for “demonstrating kindness and care in the treatment of animals in the medicine and surgery clinics.” To Dr. Khor, this isn’t just an award, but a core philosophy that she carries with her today.
