Dr. Efrain Vassallo was born and raised in Ponce, Puerto Rico, and is fluent in Spanish and English. He knew from a young age he wanted to become a veterinarian. Dr. Vassallo said the movie “Jurassic Park” was what first interested him in animals and science.

“I was amazed by the biology and science, so for the longest time I wanted to be a paleontologist,” Dr. Vassallo said. “But then I realized all those animals were dead, so I switched goals after that.”

Dr. Vassallo started his education at the University of Puerto Rico-Mayagüez as a pre-Vet student before graduating from Lousiana State University in 2016 with a Doctorate of Veterinary Medicine. During his time at university, Dr. Vassallo worked with an orthopedic surgeon in Puerto Rico, and at private practices in Las Vegas and Texas. Most of his externships were small animals, but he has some experience with farm animals.

“I really like interacting with clients and pet owners, so that’s why I prefer small animals,” Dr. Vassallo said.

During his externship in Las Vegas, Dr. Vassallo saw that there were better opportunities to learn more about animal medicine and decided to relocate to Nevada. He is interested in surgery, internal medicine, and working with “misunderstood patients.”

In his spare time, Dr. Vassallo enjoys exploring the Las Vegas area, trying different types of food, reading, working out, and traveling to places like Zion National Park and Phoenix. He and his girlfriend have a Greyhound named Callie, a three-legged cat named Squanchy, a Pitbull-mix named Groot, and a senior cat named Hagrid.
