Staff Veterinarian
Emergency & Critical Care
Dr. Ríos always knew she wanted to be a veterinarian. She achieved her dream by graduating from Ross University School of Veterinary Medicine after completing her clinical year at Auburn University. During school, she was very interested in surgery and oncology. After graduating, she pursued and completed a rotating internship here at VCA RIVER. Dr. Ríos developed a passion for emergency medicine which prompted her to practice as an emergency veterinarian in our facility. She is a Puerto Rico native and can communicate with clients in both English and Spanish, and is currently learning to become fluent in Portuguese. In her free time, she loves dancing, going to the beach, traveling, going to the gym and spending time with her family and friends.

Emergency & Critical Care

The Emergency Medicine Department at VCA RIVER is a full-service ICU focused on providing evidence-based medicine at an advanced, critical care level. We utilize a number of employees with expansive knowledge, experience and licensure from our board certified emergency and critical care veterinarians to our licensed technicians.

Our emergency department currently has 3 specialists boarded in emergency and critical care and 5 full time emergency veterinarians. We also have over 12 licensed technicians, several in licensing programs, and 1 pursuing their specialty license in emergency and critical care.

VCA RIVER hosts a rotating veterinary internship for 1 year following graduation from veterinary school. Our 5-6 interns rotate through the emergency department and team up with our senior emergency veterinarians and specialists to provide 24-hour care for your pets.

Additionally we have a state-of-the-art facility with MRI, CT, Hyperbaric Oxygen Chamber, Endoscopy, Fluoroscopy, digital radiography, full service in-house Antech laboratory and two surgical suites. Because we are also a specialty practice, we are able to draw upon the knowledge and experience of our boarded specialists in other departments if needed to bring your pet the best possible care. We work together as a team to put your pet's treatment and care first.
