Dr. Chris Hummel

I graduated from Purdue University School of Veterinary Medicine in 1994. I spent time practicing in Houston, Texas, and the greater bay area in northern California before moving to the greater Phoenix area in 2003. Since coming to the valley, I have worked in multiple veterinary hospitals within the Pet Vet family of hospitals as a relief veterinarian. I started working as full time veterinarian at Goodyear Animal Hospital from July 2005 to September 2007 before transferring to Westbrook Animal Hospital as an owner veterinarian in 2007. I enjoy all aspects of veterinary medicine from surgery to medicine in both dogs and cats. I am working towards board certification in general practice.

My spouse and I live in northwest Phoenix with our 3 wonderful dogs, Maggie, Adam and Austin, all of whom have their own special medical problems; our 2 cats, Kazi and Stach-a-rue, and many fresh water fish. When we are not working, I enjoy playing with the dogs, touring Arizona on my motorcycle, caring for my fledgling Plumeria collection, reading and writing.

Dr. Martha Ullman

At a young age, I knew I wanted to be a veterinarian. I grew up in Northwest Indiana, near Chicago. I attended Purdue University for my undergraduate and veterinary degrees. During veterinary school, I came to Arizona for an externship and decided to return for an equine internship at Chaparral Veterinary Medical Center in Cave Creek. Since my internship, I have worked on horses and small animals. I have practiced in Indiana, Ohio, and Arizona. On my time off, I enjoy running, hiking, and spending time with my dog, Elli, and one-eyed cat, Odin.

Dr. Julia Wiederholt

I grew up in a small town in Iowa, right along the Mississippi River. I attended Western Illinois University for my undergraduate degree in Biology and graduated from Iowa State University’s College of Veterinary Medicine in 2016. I also obtained a Master’s in Public Health from the University of Iowa in 2016. I moved to the Phoenix area shortly attaining my DVM in order to escape the Midwest winters. In my free time, I enjoy reading, hiking, and tending to my large collection of houseplants and succulents. I live with my foster failure cat Big Paw Paw and my Chihuahua Nicholas.

Dr. John Schroeder

I was born and raised in Iowa where I started my career in the veterinary field working as a kennel assistant, gradually working my way up to tending to the front desk and assisting doctors with office visits. I attended University of Northern Iowa for my undergraduate work and then graduated from Iowa State as a Doctor of Veterinary Medicine in May of 2017.

In my free time, I enjoy cycling and working on craft projects. My girlfriend Amy and I also love to travel, visiting different countries, as well as all the local craft breweries. We recently adopted Piper, a Dachshund/Terrier puppy, who loves to cuddle and explore the new state with us. I am so happy to join the AZPetVet Westbrook family!

Dr. Brandy Stewart

Dr. Stewart grew up in Hawai‘i, where she met the love of her life. She attended the University of Hawai‘i at Mānoa for a bachelors and a masters in animal science. She attended Colorado State University and received her Doctor of Veterinary Medicine in 2019. Her love for animals began at a young age with a childhood pet, a kitten named Angel. Angel had Hydrocephalus (water on the brain) And, Boom! Her obsession with veterinary medicine began. Her many childhood trips to zoos and later volunteering at one ignited a passion for exotic animal medicine. Dr. Stewart loves working with exotic animals, but her main passion resides in the feline department.

Dr. Stewart and her husband fell in love with Arizona and decided to relocate! They have a long-haired kitty named Gidget and a small chihuahua mix dog named Lady. In her free time, she enjoys spending time with family, watching movies, reading, visiting zoos, and exploring the outdoors. She is excited to join the AZPetVet team and looks forward to meeting you and your furry family.

Dr. Caitlin Johnson

Dr. Caitlin Johnson was born and raised in the Valley of the Sun. She attended the University of Arizona, where she completed her undergraduate degree in veterinary science in 2015. Dr. Johnson then moved to the Caribbean island of St. Kitts, earning her Doctorate of Veterinary Medicine at Ross University in 2019. Her senior clinical year was spent at the University of Illinois, where she figured out just how much she dislikes winter, so decided to move back home to Phoenix. Dr. Johnson is interested in all aspects of small animal medicine but thoroughly enjoys soft tissue surgery. She hopes to one day expand her medical expertise to treat exotic animals, including birds, small mammals, and some reptiles.

In her free time, Dr. Johnson enjoys traveling, exploring Arizona, and spending time near the water. While at home, she enjoys watching TV with her dog Milo and two cats, JD and Luna.
