Jacqueline McCool, DVM

Practice Owner, Veterinarian

Practicing Since: 1991
Education: Auburn University

Dr. Jacqueline McCool grew up in south Florida. She realized at the age of nine that she wanted to become a veterinarian to help as many animals as possible after her first cat Papillion was hit by a car and killed.

She attended Auburn University in Alabama for both undergraduate studies and vet school. She received her Doctor of Veterinary Medicine degree in June 1991. She practiced in Florida for one year then moved to California to be closer to her family.

She has practiced in Livermore, CA, since August 1995 and purchased Del Valle Pet Hospital in September 2000. She is a member of American Animal Hospital Association, American Veterinary Medical Association, California Veterinary Medical Association and American Association of Feline Practitioners.

Her two children, Ryan and Caitlin are also animal lovers. They currently share their home with a rescue cat named Beetle, a beautiful yellow Lab named Keane and a Dachshund/Chihuahua mix named Guinness. When she is not working, Dr. McCool enjoys working out and doing outdoor activities with her family.

Karin Connor, BVMS

Karin Connor, BVMS

Practicing Since: 2007
Education: University of Glascow

Dr. Karin Connor grew up and went to school here in Livermore. Her grandfather was a veterinarian in southern California, and she was happy to be taught at a young age how to give medications and injections to her own pets under his supervision. She even got to watch her first dog get neutered! She grew up with dogs, cats, rats, and her horse and cannot remember a time when she did not want to be a vet too.

After attending Granada High School she went for her undergraduate at U.C. Berkeley and completed her junior year abroad in Glasgow, Scotland. She was accepted into the Veterinary School at the University of Glasgow for the following year where she completed her BVMS (the Scottish veterinary degree). She has fond memories of her patients in Scotland; her first spay was a West Highland White Terrier in the West Highlands and de-horning Highland calves on small remote islands off the coast of Scotland. While living in Scotland, she met her husband, Christopher, and when she graduated in 2007, they moved back to California.

She loves spending time with her husband and their 2 young children.

At home she is surrounded by her pets; the cats-“Bonnie” and “Clyde” and “Spike” all DSH tabbys. As well as the dogs-“Mackintosh”- a Malti-poo, “Tim”- a Chihuahua, and “Dave”- a Labradoodle- all rescues.

In her spare time, she loves watching mystery TV shows and reading.
