Dr. Amanda Marsella

Associate Veterinarian

Dr. Amanda Marsella’s lifelong passion for veterinary medicine was inspired by her experiences growing up with a diverse array of animals, including horses, dogs, cats, turtles, gerbils, a bird, and a rabbit. Her early exposure to animal care solidified her desire to become a veterinarian. Dr. Marsella completed her undergraduate degree before attending the University of Toronto, where she earned a Master of Science degree from the Faculty of Medicine. She then graduated from the Ontario Veterinary College in 2013, where she received a comprehensive education in veterinary medicine. Her clinical training includes several mixed animal rotations and a specialized training program at the Atlantic Veterinary College in Prince Edward Island, where she focused on acupuncture and complementary medicine. This diverse training has equipped her with a broad skill set, particularly in caregiver support, where she excels in helping families understand and provide the best care for their beloved pets. When she’s not at the clinic, Dr. Marsella enjoys spending quality time with her young family and their Labrador. She is also an avid hockey player, often found on the ice at Withrow Park, and is a dedicated fan of the Toronto Maple Leafs, cheering them on with enthusiasm. Dr. Marsella’s commitment to both her patients and their families, combined with her active lifestyle and personal interests, makes her a valued member of our team.

Dr. Sabrina DiDonato

Part-time Associate Veterinarian

Sabrina's passion and admiration for animals began at a young age, growing up surrounded by hamsters, rabbits, reptiles, birds, and a deep love for cats. Her dedication to advocating for the well-being of all animals naturally led her to pursue a career in veterinary medicine. After completing her undergraduate degree at the University of Toronto, she worked as the Program Director for Pawsitively Pets, where she educated children about various exotic animals. Sabrina earned her Doctor of Veterinary Medicine degree from the University of Melbourne in Australia, where she gained valuable experience working with farm animals in rural settings and observing exotic animals up close in their natural habitats. Her diverse veterinary placements, both in Australia and Canada—including previous work with Dr. Luckwaldt—have prepared her to help a wide range of animal species and have deepened her love for them. Sabrina has now come full circle, returning to the East York neighborhood she first called home. She and her husband enjoy spending time cheering on the Raptors with their cat, Mia, and their dog, Toby.
