The White Tanks Animal Hospital & Grooming team consists of three veterinarians, an office manager, a groomer, and about six support staff that all have you and your pets needs as our priorities. Our veterinarians are licensed to practice in Arizona and have a combined 25 years of experience, ensuring your pet will benefit from our experience, education, and up to date veterinary care and medicine.

We also are able to be fully staffed 7 days a week, so we can see you and your pet when it best fits your schedule and needs. Our staff also focuses on communication, education and compassion for our clients and patients.

All of our staff is provided continuing education to make the best health care decisions for your pet. And all of our staff members are pet owners, so we understand the

Dr. Melissa Berthiaume (Malone)

I was born and raised in Albuquerque, NM, and went to New Mexico State University in Las Cruces, where I obtained my BS in Animal Science in 2003. I attended veterinary school at Colorado State University and graduated in 2007. I practiced for several years in New Mexico, but have been in Arizona since the summer of 2011, and I love living out here in the desert heat! A few of my special interests in veterinary medicine include surgery (orthopedic surgery is something I particularly enjoy), dentistry, and preventative care. I also enjoy building lasting relationships with pets and their families – starting with that first visit and as they go through life. Watching the animals grow and bond with their families, and being here to help when illness or injuries arise are what make my job so rewarding! Outside of veterinary medicine, I enjoy anything that involves spending time with my family. I also love to have outdoor fun, especially barbeques, swimming, and camping. At home I have 2 young human kiddos, and 2 fur kids (2 pooches - a sweet pitbull and a silly cane corso).

Dr. Laural Casler

I am originally from upstate New York, but have moved around a lot with my schooling. I first moved to Arizona in 1996 for graduate school, where I studied anthropology and primate behavior. I returned to the Phoenix area after veterinary school at the University of Wisconsin-Madison, and have found my professional home as part of the White Tanks Animal Hospital team. I understand that your pets are important members of your family, and I will always treat them like my own. My goal is to keep them happy and healthy. When unplanned situations arise, I will work with you to strive to make them well. While I love all areas of veterinary medicine, I have strong interests in dentistry and internal medicine. I look forward to creating strong bonds with both you and your pets. In my free time, I enjoy sharing my life with my own furry family - my three dogs, George, Gracie, and Rona, and two cats, Tinker and Petie. I love spending time with friends, hiking, traveling, and gardening.

Dr. Gretchen Koch

I was born just outside of Philadelphia (Go Eagles!) but was raised in Gilbert, Arizona. I studied at the University of Arizona and graduated with a Bachelor of Science in Veterinary Science in 2015. I moved on to Colorado State University, where I received my Doctorate of Veterinary Medicine in 2019. While I was studying for my DVM, I worked part-time as a veterinary assistant. This experience strengthened my interest in veterinary medicine, and I knew that I had found my calling. Although I find most aspects of veterinary medicine fascinating, I particularly enjoy emergency medicine and surgery. My partner, Ashley, and I both are veterinarians; so naturally, we have a house full of pets! We share our home with our two dogs, Lucy and Kaiser, and three cats, Reid, Sunshine Boots, and Champ. I enjoy hiking, fly-fishing (I’m still learning) and baking! I'm looking forward to building long-lasting relationships with you and your furry family members.

Dr. Stephanie Athavale

I was born and raised in Southeastern, Michigan (just outside of Detroit.) I attended The University of Michigan from 2008-2012 majoring in biology and minoring in anthropology. I then went to vet school at The Ohio State University from 2013-2017, and moved to Minneapolis shortly after graduation. I worked as a small animal associate veterinarian at a private practice before making the move to Arizona in 2019. Clinically, I am interested in internal medicine, behavioral studies, and performing ultrasounds. I live with my husband, Aditya, and our 2 fur children: A Beagle-Collie mix named Jasper, and a tuxedo cat named Winston. In my free time, I enjoy reading, bird watching, and spending time with my family. My husband and I also like to go for scenic drives and nature walks!
