Our Team

Dr. Aiden Costello, DVM


Dr. Aiden Costello grew up on a small cattle ranch in Fort Jones, California. He holds a BS in Biology/Zoology from Humboldt State University and received his DVM with high honors in 2009 at Ross University in St. Kitts, West Indies.  He practiced for 3 years at a small animal clinic in Denver, Colorado before finally coming back home to the “State of Jefferson.”  During this time he developed an abundance of experience in orthopedic and non-routine surgery, providing training for visiting vets from numerous countries.  In 2015 Aiden purchased the “a” street animal clinic, and is happy to have found an environment where he can develop lasting relationships with his patients and clients.
