Preston Williams

Preston Williams, Ph.D.

Co-Founder, CEO

Welcome to ProPetDx Inc., where we are dedicated to pioneering the next generation of diagnostic tests for animals.

My name is Preston Williams, and I received my PhD in Chemistry from University of California, Riverside and have over a decade of experience in early cancer research, focusing on proteomics, metabolomics, and lipidomics.

Our mission is deeply personal to me, inspired by my beloved dog, Kipper, who succumbed to undetected late-stage cancer at the very young age of six. Despite her vibrant health, she showed no symptoms until it was too late, a tragedy that drives our unwavering pursuit to revolutionize early cancer detection and guide effective treatment plans for pet parents to follow.

At ProPetDx, we are not only committed to early detection but also to developing innovative therapeutics to treat animals with cancer and other diseases. Thank you for joining us on this journey to improve the health and lives of our cherished animal companions.
