Meet Our Veterinarians


Kyle Hacia

Dr. Kyle Hacia

Growing up in Fair Oaks, California, Dr. Kyle Hacia was raised in a household surrounded by a variety of pets that first fostered his passion in science and caring for animals. “At a young age, I had a personal experience with a veterinarian who was treating my dog for a life threatening chronic condition. Witnessing the impact her care had, not only on our beloved dog but on the entire family, allowed me to realize the vital role a veterinarian plays in preserving the human-animal bond that we all cherish as pet owners”. This eye-opening experience was instrumental in shaping Dr. Hacia’s passion for veterinary medicine.

That inspiration continues to resonate with Dr. Hacia in his committed treatment of his patients with an emphasis on empathy and compassion. “Pets have always been integral members of my family and I aspire to promote that bond in every relationship I develop with my patients and owners.” 

Dr. Hacia is privileged to cultivate these relationships with the animals and owners of his childhood community. “My goal is to create a stress-free environment for pets and owners alike. I believe that attention to client education enables owners to feel confident when making decisions regarding their animals’ care”.

Before returning to the area, Dr. Hacia obtained a B.S. in Biology from the University of California Santa Cruz. He remained in the Santa Cruz area and worked as a veterinary technician for four years prior to attending veterinary school. Dr. Hacia is a graduate of St. George’s University School of Veterinary Medicine and completed his clinical year at the University of Georgia. General practice allows Dr. Hacia to explore a variety of fascinating disciplines that medicine encompasses but he has a particular passion for internal medicine, cardiology, and soft tissue surgery.

When not at SBAH, Dr. Hacia enjoys spending time with his extended family that still reside in the Sacramento area. He also enjoys camping, hiking, and fishing with his childhood friends and his companion, Buddy, the Cocker Spaniel.
