Dr. Mayrim Pérez is a board-certified small animal internal medicine specialist in Maryland. She is based out of Anne Arundel County, and is available to serve general practice and emergency animal hospitals throughout the greater Baltimore-Washington metro area.


Mayrim L. Pérez was born and raised in Puerto Rico, and for as long as she can remember, she wanted to be a veterinarian. In 2004, she earned her bachelor’s degree in Animal Sciences with honors from the University of Florida and then earned her veterinary degree from the University of Wisconsin in 2008. After veterinary school, she completed a rotating internship at VCA Veterinary Referral and Emergency Center in Norwalk, CT, plus an internal medicine internship the following year at Animal Specialty Group in Los Angeles, CA.

Returning to the University of Florida, Dr. Pérez completed her residency in small animal internal medicine and became a board-certified internist shortly thereafter. For several years prior to joining MOVES, she worked at a busy specialty clinic in South Florida. In her free time Dr. Pérez enjoys cooking, traveling and spending time with her husband and son. She has two cats: Morrison (the silver Persian), Aries (the sassy orange tabby) & one dog: Indiana Jones (the wild mutt).

    What is a board-certified veterinary internal medicine specialist?

    A veterinary internal medicine specialist is a veterinarian who has completed advanced training in internal medicine (including a one-year internship and three-year residency) following graduation from their veterinary college. The residency training culminates with a comprehensive examination covering all aspects of veterinary small animal internal medicine. Once these requirements have been fulfilled, the veterinarian is considered to be a Diplomate of the American College of Veterinary Internal Medicine (ACVIM).

    The umbrella of small animal internal medicine includes many sub disciplines including gastroenterology (esophageal, stomach and intestinal disease), hepatology (liver and pancreatic disease), endocrinology (hormonal disease), infectious diseases, urology (urinary tract disease), nephrology (kidney disease), respiratory medicine (nose, airway and lung disease), and hematology (blood cells) & immunology (immune diseases). In many cases, the signs of a patient may include many of these organ systems. Due to their holistic approach, internal medicine specialists may also manage cases of patients with neurologic, cardiovascular or cancerous diseases, especially when these patients also share diseases within the scope of internal medicine.
