Dr. Matt Stidham

Matt Stidham

I was born at Kadlec Hospital and have happily lived in the Tri-Cities since that time. I was attracted to the Veterinary field when my Newfoundland was diagnosed with atrial fibrillation at Washington State University's College of Veterinary Medicine. I became excited by the field at that time as Veterinarians and staff offered advanced diagnostics and high quality care, while at the same time, showing a great deal of compassion for both my pet and me. I graduated from WSU's College of Veterinary Medicine in 2007 Magna Cum Laude. I enjoy many hobbies including water sports, fishing, snow skiing, marine aquariums, and cars. Most of my time is spent with my three amazing chihuahuas and cat. I am excited to have the opportunity to serve you and our community.
