Dr. Kirsten Crouch (Kraemer)

Dr. Kirsten Crouch was born and raised in beautiful Scottsdale, Arizona. She grew up on a small farm in New River, Arizona and enjoyed raising goats, sheep, horses, mules, chickens, dogs, cats, and whatever other animals she and her younger brother convinced their parents to let them raise. Dr. Crouch spent many of her younger years volunteering for the Arizona Game and Fish Department as well as Southwest Wildlife Rehabilitation Center, so her prior veterinary knowledge began early on with wildlife.

Dr. Crouch attended Arizona State University for her undergraduate degree in Biological Sciences and graduated veterinary school from Ross University with her DVM. She completed her veterinary clinical year at Colorado State University. Her special interests include pain management, cardiology, clinical pathology, and parasitology. Additionally, Dr. Crouch has a special interest in learning other languages, and she is bilingual in English and Spanish.

Outside of work, Dr. Crouch enjoys hiking, fishing, scuba diving, and traveling. She also loves spending time with her husband and their fur children: a kitty named Kaeto and a "coconut retriever" named Tonka adopted from St. Kitts during her veterinary education. Dr. Crouch is excited to meet you and your animal family!

Dr. Kristy Sorenson

Dr. Kristy Sorenson is an Arizona native who spent the first 22 years of her life between Ahwatukee, North Phoenix, and Tempe. She attended Arizona State University (go Sun Devils!), where she received her Bachelor of Science. After graduation, her husband received a job offer in Dallas-Fort Worth and the two lived there for two years. While in Texas, Dr. Sorenson worked as a veterinary technician at a small animal hospital where her passion for veterinary medicine was solidified. She received her Doctorate of Veterinary Medicine from the University of Wisconsin. After experiencing their second Midwest winter, Dr. Sorenson and her husband decided they ultimately needed to return to the warmth and sunshine. They returned to the Phoenix area immediately after Dr. Sorenson received her Doctorate of Veterinary Medicine. The two live with their boxer Sol and terrier mix Zoey in Mesa.

Dr. Sorenson's special interests related to caring for your pets include preventative care, internal medicine, and dentistry. She is passionate about creating client experiences that involve both interactive education and establishing meaningful connections with both pet and owner. She looks forward to working together as a team to build a plan for your pet's care!
