Charlotte Grasson, DVM
Dr. Grasson is a veterinarian at Torrington Animal Hospital. She grew up in Cheshire, CT, and she now resides in Litchfield. Dr. Grasson began working as a veterinary technician in Connecticut in 1999 while attending Quinnipiac University for her undergraduate studies. She quickly learned she would love to live a life helping animals and their owners. Working with the doctors there inspired her to become a veterinarian. Upon graduation from Quinnipiac in 2002, she worked full time as a technician until she decided to apply to veterinary school in 2006. Being a person who enjoys beaches and open land, she attended veterinary school at Atlantic Veterinary College at the University of Prince Edward Island in Canada, earning a DVM degree in 2010.
In her spare time, Dr. Grasson enjoys spending time with her dogs, especially exploring parks in the northwest corner of Connecticut. She also loves reading, movies, the beaches of Prince Edward Island, snowshoeing and live music. Her pets include four rescue dogs — a bichon named Pufferbelly who was rescued from a puppy mill, a terrier mix named Huckleberry rescued from an Arkansas shelter, a Shih-tzu named George — and a cat named Chirps. She is very passionate about rescuing animals that need forever homes.
