Our Story

 From humble beginnings, VOI started with the knowledge and drive of several generations of Veterinary Specialists - each leaving their own mark on the advancements in animal health and orthopedics.



Claude Gendreau, DVM, DACVS


Claude is the co-founder of VOI and the founder of  Veterinary Specialty Center located in the Chicago suburb of Buffalo Grove. Claude has a long and respected history of teaching and sharing his knowledge with the veterinary community.

Decades of practical experience in orthopedic and neurological surgery also makes him a great asset in product development for VOI.



Patrick Gendreau, MBA

President and Co-owner

Patrick is the grandson of Lionel, the co-founder and first vice-president of the Canadian Veterinary Medical Association and nephew of Claude Gendreau. 

“I feel fortunate to also be in a position to serve the veterinary profession. As a teenager I had the opportunity to work in Claude’s practice during the summer months before moving to Chicago from Montreal, my birth city. A few years later, I earned a MBA degree from the University of Illinois and joined VOI.”
