Dr. Mark Caldwell, DVM

Dr. Mark Caldwell was born and raised in Arizona and comes from a family with a long history in veterinary medicine. His father was a small animal veterinarian in Tempe, and his grandfather worked as a veterinarian for the U.S. Government. Some of Dr. Caldwell’s earliest memories are of going to work with his father and learning about animal care from a young age.
That lifelong exposure shaped the way he practices today: with curiosity, compassion, and a strong focus on helping pet owners understand their options.

Education and Veterinary Training

Dr. Caldwell earned his bachelor’s degree in Veterinary Science with a minor in Chemistry from the University of Arizona. During his undergraduate years, he was also a member of the University of Arizona TriCats triathlon team and gained hands-on experience in Thoroughbred breeding and foaling.
He then attended Kansas State University College of Veterinary Medicine, the same veterinary school his father attended. While at Kansas State, Dr. Caldwell lived and worked at the university’s Large Animal Research Center, where he helped care for equine teaching herds as well as dogs, pigs, cattle, deer, and other animals involved in research studies.
Dr. Caldwell graduated with honors and received several awards and recognitions, including:
  • Francis Lucille Koss Memorial Award for excellence in large and small animal medicine and surgery
  • Society of Theriogenology Award for proficiency in animal reproduction medicine
  • Membership in Phi Zeta, the national veterinary honor society
  • Recognition as a Veterinary Scholar at the American Royal Livestock Show in 2014

Clinical Interests and Approach to Care

After veterinary school, Dr. Caldwell practiced in small animal hospitals in Colorado and Nevada before returning to Arizona in 2017. His experience across different hospitals and clinical settings helped him develop a broad, practical approach to veterinary medicine.
Today, Dr. Caldwell’s professional interests include internal medicine, surgery, preventive care, and diagnostic lab work interpretation. He is especially passionate about client education. He believes pet owners are better able to make confident decisions when they understand what is happening, what is being recommended, and why.
To Dr. Caldwell, being a veterinarian is not only about treating pets. It is also about teaching, guiding, and building trust with the people who love them.

Life Outside the Hospital

Outside of work, Dr. Caldwell enjoys spending time with Dr. Fornara, their two sons, and their dogs, cats, chickens, ducks, and tortoise. He enjoys cooking, grilling, fishing, traveling, SCUBA diving, and sailing.

He and Dr. Fornara are also involved in international animal volunteer work. In 2023, they donated time, supplies, and veterinary expertise in Puerto Vallarta, Mexico to help treat dogs with Transmissible Venereal Tumors. In recognition of this work, they were commissioned as Kentucky Colonels by the Governor of Kentucky.

Dr. Kristin Fornara, DVM

Dr. Kristin Fornara is an Arizona native whose family has been in the state for generations. Her love for animals began early by spending time with her uncle and great-uncle who were also veterinarians. By age three, she already knew she wanted to become a veterinarian, and one of her favorite childhood games was playing “animal hospital” with her stuffed animals.

She would also spend time growing up around real animals in her home and on her family’s ranch, where she helped care for cows, horses, dogs, cats, goats, sheep, a pig, guinea pigs, and chickens. From a young age, she was drawn to helping injured, abandoned, and vulnerable animals.

Education and Veterinary Training

Dr. Fornara earned her bachelor’s degree in Agribusiness with an emphasis in Pre-Veterinary Medicine from Arizona State University where she was also a member of the National Society of Collegiate Scholars. She continued her education pursuing her veterinary degree at St. George’s University School of Veterinary Medicine and The Ohio State University College of Veterinary Medicine.

During this time she also completed additional training in companion animal dentistry through the University of Illinois School of Veterinary Medicine.

After returning to Arizona, she began her veterinary career at the same clinic where she did her pre-veterinary medical training. She later became Medical Director at an AAHA-accredited animal hospital in the East Valley, where she developed extensive experience in general practice, dentistry, soft tissue surgery, internal medicine, preventive care, and diagnostic lab interpretation.

Clinical Interests and Approach to Care

Dr. Fornara has a strong interest in canine and feline dentistry, including advanced oral surgery. She understands that dental disease can be painful, progressive, and easy for pet owners to miss, which is why she places a strong emphasis on education and early intervention.

Dr. Fornara also has an interest in diagnostic labwork interpretation, internal medicine, preventative care, senior care, and general surgery.

Her approach is collaborative and compassionate. She wants pet owners to understand the “why” behind treatment recommendations so they can make informed decisions for their pets.

Whether she is performing a dental procedure, helping a puppy or kitten through their first visits, managing a chronic condition, or supporting a family through end-of-life care, Dr. Fornara brings both clinical skill and genuine care to each appointment.

Life Outside the Hospital

When she is not caring for patients, Dr. Fornara enjoys spending time with Dr. Caldwell, their two sons, Henry and Jack, and their pets, which include dogs, cats, chickens, ducks, and a tortoise. She loves visiting her family’s ranch, traveling, enjoying delicious meals with family and friends, horseback riding, hiking, and SCUBA diving.

Like Dr. Caldwell, she is also involved in international veterinary volunteer work and was commissioned as a Kentucky Colonel in recognition of those efforts.

Co-Founding Phoenix Mobile Veterinarians

In 2022, Dr. Fornara co-founded Phoenix Mobile Veterinarians with Dr. Caldwell to bring high-quality veterinary care directly to pets and families at home. As the practice grew, they expanded into a full-service Scottsdale animal hospital so they could provide more advanced hospital-based services, including dental cleanings, oral surgery, soft tissue surgery, spay and neuter procedures, X-rays, and diagnostics.

Today, their combined hospital and mobile model allow them to provide flexible care while keeping pets connected to one trusted veterinary team.

Veterinary Care Rooted in Education, Compassion, and Trust

Dr. Caldwell and Dr. Fornara built Scottsdale Animal Hospital & Phoenix Mobile Veterinarians to provide the kind of care they believe pets and their families deserve: thoughtful medicine, transparent recommendations, and a veterinary experience that feels personal.
As Arizona veterinarians, pet owners, parents, and practice owners, they understand the role pets play in family life. Their goal is to help dogs and cats in Scottsdale, Phoenix, Paradise Valley, Fountain Hills, Mesa, Tempe, and surrounding communities live healthier, more comfortable lives.
