Veterinary Specialist Referrals

Metzger Animal Hospital has three board certified specialists (Fred Metzger DVM, MRCVS, Diplomate ABVP, Mark Koshko DVM, Diplomate ABVP and Guillermo Couto DVM, DACVIM-Oncology and Internal Medicine)! Our top priority is to make sure that our patients receive the highest standard of care and best possible outcome. This is why our doctors completed advanced training and passed specialty examinations and have the designation of certified veterinary specialists.

We are the ONLY hospital in central PA. with board certified specialists.

ABVP Diplomates are certified in Clinical Practice for the species in which the certification was granted. Clinical Practice as it pertains to veterinarians is the art and science of applying medical knowledge to animals for their care and the alleviation and prevention of their diseases.

Most veterinarians who are performing broad based clinical practice are not board certified. So how do ABVP Diplomates differ from them and how do discipline specialists differ from a non-boarded veterinary practitioner who may limit their practice or claim to have a special interest or expertise in a certain discipline ?

The answer to both is in the depth of knowledge and competency in their field and the level of veterinary service the board certified veterinarians are able to provide and the fact that they have demonstrated this by completing the certification process by a recognized specialty organization.

The ABVP board certified veterinarian has demonstrated by the certification process that they are capable of providing a level of clinical practice that is clearly superior to the norm of the profession. It is the goal of the ABVP that practitioners who excel in the art and science of clinical practice would seek certification.

Our veterinarians make every effort to stay current and skilled in many aspects of animal health, providing comprehensive care for your pet. However, board-certified specialists have extensive experience and training in a particular area of veterinary medicine or surgery. And specialty clinics and university-affiliated referral centers have specialized equipment to perform procedures that are not routinely undertaken by general practitioners.
Dr. Couto is a specialist in both veterinary oncology and internal medicine and is a internationally recognized expert in both disciplines. Visit for more information about veterinary internal medicine specialists.
