Dr. Wheaton is a Colorado native and the son of a veterinarian. He has been around veterinary medicine almost his entire life, often observing medical procedures and helping out around his dad’s clinic in rural eastern Colorado. After he served in the US Navy onboard the USS Carl Vinson, Dr. Wheaton earned his Bachelor’s Degree in Nuclear Engineering at Excelsior University.

Tanner Bishop, CVT
Certified Veterinary Technician
Hello, My name is Tanner Bishop. Born and raised in Iowa with a passion for animals and the outdoors. When I’m not working, I can usually be found at a disc golf course, slow-pitch softball fields, or hiking with my dogs. My oldest dog, Rudy, a sweet Pitbull who loves spending time with his dad and rolling in the most foul-smelling stuff he can find. The youngest is Dale, a Jack Russell Terrier, who only cares about his food and who might throw his ball next. Life is good!
