A native of Kansas, Dr. Ulitchny has grown to love our desert environment and life in Las Vegas.  When not practicing you can find Dr. Ulitchny involved in a variety of activities with his family and the community. Whether it’s his experiences with Red Rock Search & Rescue, racing cars with his son or biking and hiking with his family there is always something keeping him on the move.   

Dr Z

Kristine Ziegler DVM

Dr. Ziegler is native to Las Vegas and a true desert rat! Her parents moved to Las Vegas in 1966 for her father's career as a nuclear physicist and her mother's as a medical technologist at Sunrise Hospital. Dr. Ziegler always knew she would be a veterinarian, but her first introduction to the field was when she was hired as a kennel attendant by Dr. Pennell at the age of 16. She continued to work various positions for him over the next 8 years. And yes, he did have something to do with her attending Washington State University where she earned her Doctorate of Veterinary Medicine in 1998.

Dr. Ziegler has special interests in rescue work, dentistry, internal medicine, and of course any adorable kitten or puppy. She loves her loyal clientele, as many she has known her entire life. She is also an anesthesia examiner for veterinarians who graduated from non-accredited veterinary colleges around the world.

When she is not involved with veterinary work, Dr. Ziegler enjoys the outdoors, skiing, and most of all being a mom to three wonderful children. In Addition, she is also a Fur-Mom of 6 Fur-babies and 1 grand Fur-Baby. She knows what it means to love pets as part of the family.

Dr Smith New

Caley Smith DVM

Dr. Smith is a newcomer to Las Vegas and is incredibly excited to be joining the team at Sahara Pines.

After high school, Dr. Smith went on to Malone University in Canton, Ohio where she earned her Bachelor’s in Biology and played collegiate softball. The final stop of her schooling was the Ohio State University College of Veterinary Medicine in Columbus, Ohio where Dr. Smith earned her Doctorate of Veterinary Medicine. Dr. Smith’s special interests in veterinary medicine include nutrition (specifically weight management!), dentistry, internal medicine, and dermatology. Also important to Dr. Smith is practicing “Fear-Free” Medicine in order to give each of her patients the best possible experience in the veterinary hospital.

Outside of the hospital, Dr. Smith enjoys spending time with her husband, Aaron and their two cats. Together, they enjoy exercising and spending time outdoors. While Dr. Smith says she enjoys a good hike, her true happy place is on her paddleboard in Lake Mead. Dr. Smith and her husband can also often be found spending long hours in their kitchen cooking healthy meals.
