Learn Who We Are

  • Dr. Arzem

    Raised in Toronto, Dr. Gary Arzem has been practicing veterinary medicine for more than 25 years. His special interests and training include internal medicine, ultrasound, ophthalmology, cardiology, surgery, emergency medicine and preventative medicine. For years, his dream was to run a full-service animal hospital for pets, meeting all their veterinary healthcare needs and providing exceptional client service.

    Dr. Arzem has realized that dream at North Yonge Veterinary Hospital. He strives to meet every patient’s unique needs and works hard to explain to clients every aspect of their pet’s care. He is passionate about preventative medicine as well as progressive treatment and surgery. He enjoys his relationships with his clients and loves informing them on the various details of pet health care that ensure every pet enjoys a healthy and happy life.

    When he is not taking care of his patients, Dr. Arzem enjoys spending time with his family outdoors. His interests include travel, baseball and golf. He admits the music is a passion he couldn’t live without. A veterinarian who has dedicated his life to taking care of animals, he is especially proud when clients refer friends and family to his practice due to the excellent and thorough care their pets receive and the superior service his staff offers at North Yonge Veterinary Hospital.

  • Dr. Hansford

    Dr. Hansford completed her Bachelor of Science at the University of Guelph before graduating from the Ontario Veterinary College with her Doctor of Veterinary Medicine in 2004. She has a special interest in avian and exotic animals and, before graduation, enjoyed spending time at Jungle Cat World, the Bowmanville Zoo and the Metro Toronto Zoo. Since then, she has continued to expand her knowledge base through work at various exotic hospitals.

    While Dr. Hansford loves all species of animals, she has devoted extra time to studying exotic pets including rabbits, guinea pigs, skinny pigs, ferrets, hamsters, rats and other small furry pets. But in her heart, she is a cat person. Growing up surrounded by cats, she developed a particular understanding and affinity for felines. She has dedicated considerable time learning about cats, and she strives to bring them as many medical and surgical options as her canine patients.

    Dr. Hansford believes the best patient care is a two-way street. She works hard to ensure all her clients feel comfortable talking honestly about their pets, and at the same time, aims to share her medical knowledge and advice as honestly and openly as possible. She loves working with a family to make sure their pet—whether it’s a tiny hamster or a huge Great Dane—enjoys a happy and fulfilling life.

    Outside of work, Dr. Hansford enjoys spending time with her husband and two sons, often exploring the outdoors. Although the menagerie often changes, she currently shares her home with Pixie, her opinionated cat, a Beta fish named Isa and a corn snake named Marlowe. At home and the clinic, Dr. Hansford believes there’s nothing more important than the loving relationship between a family and their pet.
