Marina Mavromatis
DVM, DACVR
Board-Certified Radiologist, Owner
Dr. Marina Mavromatis graduated from the North Carolina State University College of Veterinary Medicine. She also completed a residency in diagnostic imaging at Tufts University Cummings School of Veterinary Medicine to become a diplomate of the American College of Veterinary Radiology in 2017.
While she appreciates all aspects of diagnostic imaging, she particularly enjoys teaching, musculoskeletal imaging, and imaging-guided procedures. She contributes to the future of veterinary medicine by providing locum contracts to universities and has published peer-reviewed research in Veterinary Education. Unlike many other radiologists, Marina looks forward to meeting with clients to discuss imaging results during outpatient appointments and can partner with your primary care veterinarian to help determine the best next steps for your pets.
Marina and her husband, Michael, enjoy traveling the world by cruise ship or hopping in a small plane for quick flights (Michael is a licensed pilot). When they aren’t traveling, they enjoy visiting local gardens, wineries, breweries, and locally-owned restaurants. They share their home with many furred, feathered, and scaled pets and you may have spotted the 325-gallon semi-aggressive saltwater FOWLR tank in some of our UVPP videos!
