The Staff at Our Pet's Vet


Dr. Kaytee Brenes

Dr. Brenes grew up in Mission Viejo. She received her undergraduate degree from the University of California, Berkeley and then attended UC Davis for veterinary school. She graduated from Davis in 2004. Wanting to become an even better doctor, she headed to VCA West Los Angeles to complete a 1 year Medicine and Surgery Internship. Since then she has been practicing at veterinary clinics in South Orange County. She lives in Aliso Viejo with her family. She saw the need for more personalized veterinary care for the pets and families of the area and decided to open Our Pet's Vet in 2009.

Kaytee has had show Great Danes. Maya was in shows starting at 6 months. But due to health problems as a puppy she had stunted growth. Blanche was her second show dane. Blanche was handled by Diane Collings in Northern California and won several shows. She finished at 14 months with a Best of Winners at an Arizona Great Dane Specialty beating over 60 danes.

Read What Our Clients Say

  • "Dr. Cooper was amazing, I found her to be very easy to talk with, she went over x-rays and discussed my options in terms that were easy to understand. I didn't feel pressured, and ultimately we decided to let her remove the problem teeth. Since her check-up Katie is all kisses and her mouth smells great. Love this vet!"
