Dr. Zenko, DVM

MEDICAL DIRECTOR

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

Veterinarian

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

Veterinarian

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!

Dr. Lash, DVM

Veterinarian
Growing up in a suburb of Cleveland surrounded by cats and dogs, I knew from an early age that I wanted to become a veterinarian. I’ve been riding horses since I was 12 years old, and my passion for animals has only grown stronger over the years. I am dedicated to helping animals and the people who love and care for them. I graduated from The Ohio State University College of Veterinary Medicine in May of 2026 and earned my Bachelor’s degree in Animal Science from Purdue University in 2022. Following graduation, I moved to Arizona with my dog, Flynn, and my cat, Rosalie, who keep me busy outside of work. I first fell in love with the Prescott area, its beautiful hiking trails, and Chino Valley Animal Hospital while completing an externship here a few summers ago. I have a particular interest in soft tissue surgery, dermatology and ruminant medicine! A fun fact about me: my dog, Flynn, was adopted from Chino Valley Animal Shelter while I was here in 2024! I am thrilled to be joining the team and look forward to meeting and caring for all of our furry- and non-furry- friends.
