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 AZPetVet family of hospitals as a relief veterinarian. I started working as a full-time veterinarian at Goodyear Animal Hospital from July 2005 to September 2007 before transferring to Westbrook Animal Hospital as a partner/veterinarian in 2007. I enjoy all aspects of veterinary medicine, from surgery to medicine in dogs, cats and small mammals, such as guinea pigs and ferrets. My spouse and I live in northwest Phoenix with our 3 wonderful rescue cats, Kazi, Stache and Cricket and our geriatric dog, Adam. When we are not working, I enjoy playing with the dog, kickboxing, walking, hiking, cycling, TaiChi, caring for my plumeria collection, reading and writing.

Dr. Martha Ullman

I grew up in the Northwest Indiana/Chicago area. I graduated from Purdue University in 2009. I first moved to Phoenix for an internship after school but returned to the Midwest to work in several states before ultimately returning to the valley. My interests in practice include preventative medicine, surgery, diagnostic imaging, and dentistry. In my free time, I enjoy hiking, running, baking, and equestrian sports. I live in the Phoenix area with my husband, our dogs: Elli and Freya, our one-eyed cat: Odin, and our Sulcata tortoise: Tyre.

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 after receiving 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 domestic shorthair Big Paw Paw, Chihuahua Nicholas, poodle mix Liam, sphynx Winston, sand boa Groot, and sulcata Odysseus.

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 have joined the AZPetVet Westbrook family!

Dr. Brandy Stewart

I grew up in Hawaii, where I met the love of my life. I attended the University of Hawaii at Mānoa for a bachelor’s and a master’s in animal science. I attended Colorado State University and received my Doctor of Veterinary Medicine in 2019. My 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! My obsession with veterinary medicine began. My many childhood trips to the zoo and later volunteering at one ignited my passion for exotic animal medicine. I love working with exotic animals, but my main passion resides in the feline department. My husband and I fell in love with Arizona and decided to relocate here! We have a long-haired kitty named Gidget and a small chihuahua mix dog named Lady. In my free time, I enjoy spending time with family, watching movies, reading, visiting zoos, and exploring the outdoors. I am excited to have joined the AZPetVet team and look forward to meeting you and your furry family.

Dr. Caitlin Johnson

I was born and raised in the Valley of the Sun. I attended the University of Arizona, where I completed my undergraduate degree in veterinary science in 2015. Then, I moved to the Caribbean island of St. Kitts, earning my Doctorate of Veterinary Medicine at Ross University in 2019. My senior clinical year was spent at the University of Illinois, where I figured out just how much I dislike winter, so I decided to move back home to Phoenix. I am interested in all aspects of small animal medicine but thoroughly enjoy soft tissue surgery. One day, I hope to expand my medical expertise to treat exotic animals, including birds, small mammals, and some reptiles. In my free time, I enjoy traveling, exploring Arizona, and spending time near the water. While at home, I enjoy watching TV with my dog Milo and two cats, JD and Luna.
