Overview

Yosemite Pet Hospital is proud to have been re-accredited by the American Animal Hospital Association (AAHA). Less than 15% of veterinary hospitals in North America have earned this distinction. We pass rigorous inspections on over 900 standards to ensure that you and your pet receive the highest level of care. We have built a small but loving, caring, and compassionate veterinary team to serve you and your pet’s needs. Our staff pride themselves on providing the most competent but gentle care for you and your pets

Dr. Lissel Madrazo has been working as a small animal veterinarian for 21 years. She started working in Lacy, WA before moving to Oxnard, CA where she worked in Banfield Pet Hospital while doing relief work in other privately-owned hospitals until January 2007. She then owned and operated a Banfield Pet Hospital franchise in Fremont, CA. She has been the owner and veterinarian of Yosemite Pet Hospital since October, 2017 and has loved getting to know Simi Valley's pets and their families
