Our Doctors

Dr. Nichole Westerweel, DVM
Dr. Nichole Westerweel

I am originally from Las Vegas, NV and moved to the Phoenix area after graduating veterinary college in May 2009. I received my Bachelor of Arts from Cornell University, and went on to graduate from the Kansas State University College (go Wildcats!) of Veterinary Medicine shortly thereafter. Before joining White Tanks Animal Hospital, I completed a one-year rotating small internship with the VCA Animal Referral and Emergency Center in Mesa.

During the summer of 2010 I moved to northwest Phoenix and absolutely love it here! In my free time I love to be outdoors hiking, swimming, or camping, to name just a few activities. I have a dog named Tate who is a very mischievous boxer mix, and cat named Finnegan. They add so much joy to my life each day!

While I love all aspects of veterinary medicine, my personal interests lie in internal medicine, surgery, and nutrition. I strongly believe that the relationship between you and your pet is special, and something to be treasured for a lifetime. My animals are like family to me, and I treat each patient as though they were my own. I look forward to getting to know you and your furry loved ones!

Dr. Johanna DeKing

Dr. DeKing is originally from the Midwest and spent time growing up in Illinois and Wisconsin prior to moving to Arizona with her family. She attended Arizona State University, graduating summa cum laude with a bachelor's degree in Agribusiness in 2005. Dr. DeKing earned her Doctor of Veterinary Medicine from Washington State University in 2009, and graduated as a member of the Phi Zeta Veterinary Honor Society. Following graduation, she completed a one year internship at Washington State University in order to further expand her knowledge in areas of emergency and critical care, oncology, internal medicine, and surgery.

Dr. DeKing shares her home with four dogs, Gonzo, an Australian cattle dog, Boomer, a border collie, and Sawyer and Emmett, both mixed breed dogs. In her free time, Dr. DeKing is an avid Chicago Cubs fan and also enjoys hiking, cooking, reading, and spending as much time outdoors with her dogs as possible.

Dr. Rebecca Thongkham

Dr. Thongkham grew up in the east valley in Arizona and dreamed of becoming a veterinarian from a very young age. She attended the University of Arizona in Tucson and obtained a Bachelor of Science degree in Veterinary Science. It was during this time that she worked at her first animal clinic and discovered the joy of caring for animals. She attended veterinary school at The Ohio State University and though she loved experiencing four seasons--complete with crisp fall leaves and white winters--upon graduation, she knew she wanted to return home to sunny Arizona. Dr. Thongkham enjoys all aspects of veterinary medicine and strengthening the human-animal bond. In her spare time she loves to cook, travel, and spend time with her husband and their collie mix named Ellie.

Dr. Leigh Ann Stastny

I am originally from Omaha, Nebraska. I attended the University of Nebraska - Lincoln for my undergraduate degree and received my Doctorate of Veterinary Medicine at Kansas State University in 1995. Since my graduation I have lived in Phoenix. I joined the Arizona Pet Vet family of hospitals in 2001. I now call Surprise Animal Hospital my home.

I have 2 dogs, a Labrador named Bonner and a mixed breed dog named Ruby. I enjoy physical fitness training and hiking to stay active and maintain a healthy lifestyle. I also love spending time with friends and family and traveling and seeing new places. I look forward to meeting you and your pets and helping you to keep them healthy and happy.
