Cardiologists & Radiologists

Dr. Christopher Paige

Dr. Christopher Paige has always been passionate about animals. Today, he is proud to put that passion to work as a veterinary cardiologist who’s been in the field for over 12 years. Dr. Paige is board-certified in Cardiology by the American College of Veterinary Internal Medicine (ACVIM). For more than nine years, he has worked in private specialty practices in Mesa, Phoenix, and Flagstaff, Arizona, where he offers full, interventional cardiology services.

In 2012, Dr. Paige was recruited into cardiovascular research at a global human medical device company and temporarily left private practice for preclinical medical device research. In 2014, he started a mobile practice to provide veterinary cardiology services to Flagstaff, AZ, and surrounding areas of Northern Arizona. For the past 4 years, he also remains an adjunct clinical faculty member at Midwestern College of Veterinary Medicine (CVM). In August 2016, Dr. Paige opened Valley Veterinary Cardiology to offer the Valley’s first cardiology-specific practice dedicated to patient, client, and primary care veterinarian support. Aside from mobile practice, he has stationary practices at various specialty hospitals in Arizona (Mesa, Phoenix, and Glendale). In collaboration with Dr. Jason Eberhardt (Internal Medicine Specialist), Dr. Paige opened Valley Veterinary Internal Medicine to expand the mobile veterinary specialty services. In 2018, he also opened AZVETIDEAS, which is a veterinary medical device consulting company.

After being a dedicated client of world-renowned human and veterinary ambulatory monitoring service, the opportunity had recently become available for Dr. Paige to maintain this high-quality service specifically dedicated to veterinary patients. Most importantly, many of the previous employees (technicians) from this large human ambulatory service have also joined Dr. Paige to help create AxisVetTM.
