Jill M. Patt, DVM offering Experienced Veterinary Care at Little Critters Veterinary Hospital in Gilbert, AZ

Jill Patt, DVM


Dr. Patt has always been deeply committed to animal care and well being and has devoted her life to improving their lives through quality veterinary care.



Dr. Patt is the founder of Little Critters Veterinary Hospital and a longstanding practicing veterinarian in Mesa, Arizona at a small animal and exotic pet hospital.

Dogs, Cats & Exotic Pet Care: 

Her focus while obtaining her veterinary degree was in small and exotic animals. The term “small animals” in veterinary medicine is used to refer to dogs and cats. While the term “exotic animals” indicates birds, reptiles, rabbits, ferrets, rodents, and other “unusual” pets. Because she has vast personal experience with exotics and has kept, shown, raised and basically spent her life with all of the above types of animals she  felt that this species tract was the perfect choice for her.

Goal is Quality Care: 

Dr. Patt's goal in her practice of veterinary medicine is to provide the furry, feathered, or scaly patients with the care and attention their guardians would expect for themselves.

Love of Animals: 

All her life, her home has been filled to overflowing with “little critters” of all types. As long as she can remember she wished to become a veterinarian and had worked towards that goal.

Committed to Education and Knowledge: 

She was fortunate enough to attend WSU where she completed her bachelors in veterinary science, graduating Magna Cum Laude. She also obtained her Doctor of Veterinary Medicine degree from WSU where she was a member of the veterinary honors society of phi zeta and again graduated Magna Cum Laude. 


In 2000 she graduated Magna Cum Laude from Washington State University School of Veterinary Medicine & started practicing her passion. During this time she was responsible for starting an exotic animal veterinary practice at her Mesa, AZ location, volunteered at the Medical Shelter of the Humane Society, taught at the Mesa Community College Veterinary Technician Program as adjunct faculty and helped start Animal Doctors to the RESCUE. 

In 2012 she married a wonderful man who is a practicing human pharmacist. She is fortunate that her husband shares her passion for animals and understands her dedication to patient care.

In 2016 she opened the doors of Little Critters Veterinary Hospital in Gilbert, AZ to allow her to continue her goal of exceptional patient care for all types of little critters.

Additional interests include Canine Sports Medicine, Canine Reproductive care and Preventative health care. She is also very experienced in the general practice of veterinary dentistry. 

Dr. Patt provides medical, surgical and dental care to all types of critters and has a passion for Pomeranian Dogs & exotic pets.
