EMERGENCY VETS AND URGENT CARE IN Anaheim Hills, CA
welcome to VEG Anaheim Hills!
Dr. Veronica Villanueva
Medical Director
Colorado State University; Western University of Health Sciences
Dr. Villanueva (V) was raised in Albuquerque, NM, but her heart has always been in SoCal. She graduated from Colorado State University (Go Rams!) with a bachelor’s degree in Biology and a minor in Neuroanatomy/Biomedical Sciences. She went on to earn her Doctor of Veterinary Medicine from Western University of Health Sciences in Pomona, CA, in 2011.
After graduation, Dr. V was accepted into a competitive, AVMA-approved small animal emergency and surgical rotating internship at Pet Emergency and Specialty Hospital in Thousand Oaks, CA. During this internship, she discovered her passion for small animal emergency medicine and exotic pet care. She returned to New Mexico, where she served families and their pets for over eight years, before making her way back to Southern California to provide compassionate and practical care for pets of all kinds.
Her special interests include emergency surgery, critical care, endocrine emergencies, wound care, pain management, diagnostic ultrasounds, and mentoring fellow veterinarians. Dr. Villanueva has a special place in her heart for senior and geriatric pets and values the human-animal bond, no matter the species.
Dr. Villanueva enjoys spending time with her husband Anthony, their daughters and son, and four-legged babies: Kiki (a French Bulldog), Clementine (a Pug), and Torkoal (a Desert Tortoise). In her free time, she loves listening to music, practicing hot yoga, fishing, and watching Major League Baseball.
