Dr. Maher traces his roots back to the state of Rhode Island where he was born and raised. Dr. Maher attended Providence College where he achieved a Bachelors of Science degree in Biology. His veterinary education took place at Tufts University School of Veterinary Medicine where he earned his DVM degree. He remained in the greater Boston area for his internship and served 2 years on staff at the South Shore Veterinary Associates before returning to Tufts University to complete a 3-year residency in internal medicine.

A move to the wild, wild west took place after completion of his residency where he practiced internal medicine at the Pet Medical Center – Granada Hills in the San Fernando Valley of Los Angeles for 11 years. It was the California Veterinary Specialists who prompted Dr. Maher and his wife Margie to move to North County San Diego in 2002. Dr. Maher remained a member of the internal medicine department at CVS practicing internal medicine in the San Marcos, Murrieta, and Carlsbad facilities through 2008. From 2009 forward Dr. Maher gained valuable experience practicing veterinary internal medicine at the Animal Urgent Care and Specialty Group (Escondido), the Veterinary Medical & Surgical Group (VMSG-Orange County) and recently the Veterinary Emergency and Referral Center of Hawaii (Honolulu). It was his desire to reunite with his friends, colleagues and extended Ohana at the VCA – California Veterinary Specialists that lured him and his family to leave island life in Oahu and move back to sunny San Diego!

Dr. Maher is board certified in veterinary internal medicine (ACVIM) and is a board-certified practitioner (ABVP). He enjoys all aspects of internal medicine but has special interests in endocrinology, gastroenterology, and cardiology. He has extensive experience performing a variety of endoscopic and laparoscopic procedures (i.e., upper/lower GI endoscopy, rhinoscopy, bronchoscopy, urethroscopy/cystoscopy and laparoscopy for minimally invasive organ biopsy). He has completed extensive training in abdominal/thoracic ultrasonography and echocardiography and has over 20 years of experience in performing these imaging procedures.

When not practicing veterinary internal medicine Dr. Maher enjoys spending time with family (Wife Margie, 2 dogs – Desi and Benny and their Meyer’s parrot Cricket), golfing, skiing, hiking and being a faithful fan of his beloved NE Patriots, Boston Bruins, Boston Celtics and World Series Champion Boston Red Sox.

What Is A Veterinary Internal Medicine Specialist?

A board certified veterinary internal medicine specialist is a licensed veterinarian who has obtained intensive, additional training in understanding how your pet's internal body systems function and in diagnosing and treating the many serious diseases that can affect the health of those systems. An internal medicine specialist has advanced training in the following disciplines:

  • Cardiology
  • Gastroenterology
  • Hematology (study of the blood)
  • Immunology
  • Infectious Diseases
  • Nephrology/Urology
  • Neurology
  • Respiratory Diseases
  • Oncology

While your general practitioner veterinarian can diagnose and treat many health problems, certain diseases and conditions require the care of a doctor who has had specialized, intensive training in internal medicine in order to provide the very best outcome for your pet.

*Within the discipline of veterinary internal medicine, there are also veterinarians who specialize further in Small Animal Medicine, Cardiology, Neurology, and Oncology.

Why Does My Pet Need A Veterinary Internal Medicine Specialist?

Just as your own primary care physician may feel the need to refer you to the care of a specialist from time to time, your general practitioner veterinarian may feel your pet needs a specialist to help diagnose or treat a particularly complicated medical problem. While your general practitioner veterinarian can handle many aspects of your pet's care, just as in human medicine, there is sometimes a need for the attention of a specialist. You can be assured that a veterinarian who knows when to refer you and your pet for more specialized diagnostic work or treatment is one that is caring and committed to ensuring that your pet receives the highest standard of medical care for his or her problem.

While in some cases, your veterinarian may be able to simply consult with a specialist about your pet's care, in other cases it is necessary to actually refer you and your pet to the specialist for more advanced diagnostics and treatment. Board certified veterinary internists may also have access to specialized diagnostic or treatment tools that a general practitioner veterinarian may not have.

What Health Problems Does A Veterinary Internal Medicine Specialist Treat?

Board certified internal medicine specialists are trained to treat the most serious diseases and health problems that affect pets. They are also especially prepared to care for pets that may be facing multiple health problems. Thanks to better health care, more and more pets are living longer lives. As a result, an increasing number of older pets, just like older people, are coping with multiple disease states that can be very difficult to manage. For example, a cat with diabetes may also be suffering from kidney failure, or a dog in heart failure may also be diagnosed with cancer. Internal medicine specialists are uniquely prepared to oversee the care of these complicated cases. In other situations, a younger animal may develop a problem that used to be considered untreatable but is now manageable and perhaps even curable.

Here are some common diseases that frequently lead general practitioner veterinarians and concerned pet owners to seek the expertise of a specialist:

  • Cancer
  • Heart Disease
  • Gastrointestinal Diseases
  • Diabetes Mellitus
  • Immune Related Disorders
  • Kidney Dysfunction

Why Can't I See an Internal Medicine Specialist All the Time?

In some cases you can. In many practices, the general practitioner veterinarian at a practice is also a boarded internal medicine specialist. General practice veterinarians, however, are also highly educated medical professionals who must meet ongoing continuing education requirements throughout their professional careers in order to maintain their licensure. When a specialist is needed, he or she is only a phone call or a visit away.
