Meet Our Team

Dr. Russell Greene is board certified in both Small Animal Internal Medicine and Bacteriology & Mycology. Dr. Greene is a 1983 graduate of the School of Veterinary Medicine at the University of California, Davis. He completed his small animal medicine & surgery internship at Texas A & M University, and completed his small animal internal medicine residency at North Carolina State University. While at NCSU, he obtained his PhD in Veterinary Microbiology. He then went on to do post-doctoral work in bacteriology, in Germany. In 1988, Dr. Greene became board certified in Small Animal Internal Medicine, and the following year he became board certified in Bacteriology & Mycology.

Dr. Greene has taught at the College of Veterinary Medicine at North Carolina State University; has worked as an Internal Medicine Consultant at Southwest Veterinary Diagnostics; and has run two veterinary microbiology laboratories. He has spoken at both national and international veterinary conferences. In addition, he has authored numerous publications, including the chapter on Coccidioidomycosis (Valley Fever) in the text, Infectious Diseases of the Dog and Cat. Dr. Greene has been providing internal medicine consultations and special procedures (ultrasound, endoscopy, stent placement, and other interventional procedures) to Arizona veterinarians in the Greater Phoenix Metropolitan Area and the Prescott region since 1992—longer than any other small animal internist in the area.

Kathrine is our Office Manager, and is very involved with the medical reports. Here, she is shown with Tuesday, a very tame alligator at the Phoenix Herpetological Society, who needed an abdominal ultrasound evaluation.

We have a friendly and experienced office staff to take your calls, set up appointments, and help with the medical reports. Quinn (on left), Heather (on right), and Nicole will go out of their way to help you in any way they can. All of our staff are animal lovers, who truly care about the pets we serve. Quinn is holding Hermione, one of our loyal office cats.

Dr. Greene always has one of our experienced and compassionate veterinary technicians to assist him. Adrian (on left) and Julie (center) assist Dr. Greene with his procedures in the Greater Phoenix Metropolitan Area, often driving over 200 miles in a day. The PVIMS van houses a small office, and carries the specialized ultrasound and endoscopy equipment that gets brought into the clinics of our referring veterinarians. Brianna (on right) assists Dr. Greene when he travels to the Prescott area to do procedures, one Saturday a month.

For every patient we see, a medical report is generated that is then faxed or emailed to the referring veterinarian, generally within 24 hours. Our medical records program was created especially for us by our talented computer programmer, John, to meet the unique needs of our practice. Not surprisingly, John is also a big animal lover.

Dr. Greta Heidner serves as the Hospital Director. Here, she is holding Harry, one of our hard-working office cats. She and Dr. Greene are married, and they have one son. As a small specialty practice, with long-time employees, PVIMS is able to provide our referring veterinarians and clients with a level of responsiveness and personal service that may be lacking in a larger practice setting.

Dr. Heidner is board certified in Oncology. She is a 1983 graduate of the School of Veterinary Medicine at the University of California, Davis. She completed her small animal medicine & surgery internship at the University of Illinois, Urbana, and completed her clinical fellowship in Oncology at North Carolina State University. In 1993, Dr. Heidner became board certified in Oncology. She has worked as a Clinical Instructor in Oncology at NCSU; at several small animal general practices; and at her own oncology specialty practice. Dr. Heidner brings her expertise to PVIMS.
