About Mosaic PetCare

Tracey Ruzicka

Partner & Regional Operations Director

With over 25 years as an RVT and nearly two decades in management, Tracey Ruzicka brings deep expertise in both companion and large animal care. Originally from Saskatchewan, she moved to Calgary in 2000 and has dedicated her career to supporting veterinary teams and the pets they care for.

A passionate Saskatchewan Roughriders fan, Tracey has even had her 15 minutes of fame on TSN, much to the delight of her family (and her mother’s Christmas newsletter).
