Michal Grygowski

Veterinary Assistant

Michael just completed his third year of Life Sciences at McMaster University. He is very interested in pursuing Veterinary Medicine in the future. He enjoys caring for animals, learning about their physiology, and working at the hospital. At a young age, Michael was most likely to be found either reading a giant encyclopedia about wildlife or playing his beloved game “Zoo Tycoon”. He spent countless hours, day upon day, building his own fictional zoos where he would have to feed, heal and breed many different animals. This mindset of his youth remains with him to this day, as owning a zoo continues to be his wildest of dreams. Additionally, Michael is a sports fanatic and enjoys performing and writing music. Michael has worked at Applewood Veterinary Hospital for the last three summers.
