Our Mission

Arizona Equine Mission

“Our main goal is to provide the highest quality veterinary medicine along with excellent client service to horse owners.”

This means that we not only diagnose and treat the horse’s problems, but that we address all of the owner’s concerns and explain any questions to their satisfaction.



Arizona Equine is permanently staffed with five veterinary specialists and four intern veterinarians.

  • Dr. Gayle Leith has worked at the clinic since 1988 and specializes in reproduction and preventative health. She is board certified by the American board of Veterinary Practitioners.
  • Dr. Scott Taylor has worked here since 1993, specializes in surgery and is board certified by the American College of Veterinary Surgeons.
  • Dr. Ed Voss has worked at Arizona Equine since 1995, specializes in internal medicine, and is board certified by the American College of Veterinary Internal Medicine.
  • Dr. Tresha Robinson joined us in the spring of 2000 and concentrates her efforts in dentistry reproduction, preventative health care, and is now certified in Equine Acupuncture.
  • Dr. Rick Howard joined Arizona Equine in June of 2005. His major interests are orthopedic and soft tissue surgery and the diagnosis and treatment of equine lameness.


In this day and age of technology, advanced equipment is a necessity. Our ability to accurately diagnose and treat patients is magnified many fold by judicial use of appropriate equipment. Conversely, the use of advanced equipment without knowledgeable veterinarians to use the equipment and interpret the results is not of much use.

Diagnostic equipment that Arizona Equine has in place includes:

  • 1000 ma radiography
  • Nuclear Scintigraphy
  • Advanced ultrasound equipment, including Doppler mode
  • Computed radiography
  • Digital Radiology
  • Blood gas analysis
  • Video endoscopy (1 and 3 meter capability)
  • Laparoscopy
  • MRI

Therapeutic equipment in use includes:

  • ASIF equipment for fracture repair
  • Laparoscopy
  • CO2 surgical laser
  • Diode surgical laser
  • Shockwave
  • Arthroscopy (both 30 and 70 degree scopes)
  • Sling recovery system
  • Embryo transfer equipment
  • Cooled and frozen semen capabilities


Like any large hospital, the support staff is indispensable to obtaining the mission of Arizona Equine.

  • We have several certified veterinary technicians including Julie Martin, Wendy Taylor and Darcy DeCrescenza.
  • There are also veterinary assistants, including Jennifer Zawacky, David Barth, Tracy Nelson, Trista Mills, Celeste Short, Debbey Winters, Carrie Hilton, Nicole Woedl, Wendy Larson, and Angela Sorenson.
  • Our office staff includes Sarah Henneberry, Lisa Burton, Renee Ramierz, and Breigh Cox.
  • Ramon Guerrero and Larry Anthony are essential to our operation as the Barn Managers.

These exceptional staff members help with the day-to-day chores involved in running the hospital. Without them, the clinic could not function properly.


Arizona Equine started in 1984 with construction of the main hospital. In 1991 a larger barn was added to provide more inside stalls and room for the nuclear scintigraphy facility. In 1996 outside pens were added to give us a place to house horses that did not require intensive care. In 1999 we added another treatment room, more doctor’s offices, and more storage room. The physical facility has proven to be very functional and is a great asset in helping Arizona Equine provide exceptional veterinary care.
