Our Veterinarians

Dr. Zenko, DVM


I was born and raised on a small farm in Connecticut with every farm animal on it. I completed my undergraduate degree at University of Connecticut and majored in Animal Science. I went on to complete veterinary school at Midwestern University. As I’ve always said, “since I grew up with it all, I love it all.” That hasn’t changed since completing vet school, I truly love all animals. My special interests are surgery and international travel to work with wildlife. I never thought I’d end up taking a job in Arizona but being an avid hiker, I’ve fallen in love with the mountains here. I currently have a Swedish Vallhund, Cowboy Corgi, German Shorthair Pointer, and a Brittany that share in my adventures whenever possible. I’m looking forward to becoming part of the family at Chino Valley Animal Hospital.

Dr. Fernandez, DVM


I was born in Texas and raised in a small farming community in Oregon. I graduated from Oregon State University and I am the 10th Veterinarian in my family. I have been practicing medicine in the tri-city area for 18 years. My passion is to enhance the human-animal bond and I feel I can relate to people from all walks of life. I enjoy doing orthopedic surgical procedures and physical therapy options such as our hydrotherapy treadmill, acupuncture and laser.

Dr. Kortge, DVM


I am from northern Illinois, about an hour north of Chicago, where I grew up having a large assortment of pets, including Guinea pigs, rabbits, horses, birds, cats, dogs, horses, reptiles, and more.

I completed my undergraduate degree at Southern Illinois University in Carbondale, and went on obtain my DVM at University of Illinois. I originally wanted to become a teacher because I absolutely love to educate, but throughout my life my passion for animals and medicine became the center of my world. I decided to persue my love for teaching through becoming a veterinarian. My special interests include soft tissue surgery, internal medicine, and exotic animal medicine.

I have always loved horse-back riding, hiking, and camping, so I decided to move Arizona to enjoy the gorgeous scenery, trails, and weather. The people here are pretty wonderful too! I currently have two Shetland Sheepdogs, two Pyranese mixes, two cats, two goats, a horse, a bearded dragon, and a growing flock of adorable chickens that all fill up a huge part of my heart. I have been blessed to become a member of the Chino Valley Animal Hospital family and look forward to meeting new people and pets each and every day!
