Dr. Hillary Merry is a new Veterinarian with Parkville Animal Hospital. Dr. Merry earned a Bachelor's degree in Psychology from the University of Wisconsin - Madison in 2013. She received her Doctorate of Veterinary Medicine from Cornell University College of Veterinary Medicine in 2022.

Dr. Merry grew up riding horses from the age of five and competed in hunter/jumper shows throughout middle and high school. This was where she learned her first set of veterinary skills. Immediately following graduation from UW-Madison in 2013, she took a full-time job at the animal shelter she'd been volunteering at through college. After working as an Animal Care Supervisor at a small shelter in Oregon, she decided to go back to school for her DVM, starting with prerequisites. While taking prerequisite classes at Northwestern University, she worked full-time at a small animal general practice where she discovered her passion for primary care and developing relationships with clients. During veterinary school, Dr. Merry developed a particular interest in soft tissue surgery, ophthalmology, and clinical pathology.

Originally from Monerey, California, Dr. Merry has moved out east slowly. Prior to settling in Baltimore, Dr. Merry lived in upstate New York, Chicago, and a couple different places in Oregon and Wisconsin. Dr. Merry's immediate family still lives in Monterey, California. In her free time, Dr. Merry enjoys visiting with friends and family, walking and hiking outdoors, playing video games, meditating, and spending time with her partner, Greg, and their three cats: Jazmin, Bean, and Tiger Millionaire.
