Memberships in AVMA, MVMA, AAFP, AAHA

Dr Sanders is a 1995 graduate of Tufts University School of Veterinary Medicine. She holds a Bachelor of Science degree from The College of Life Science and Agriculture at The University of New Hampshire. While an undergraduate student, Catherine began work with the dairy herds at UNH and later on as a full time staff member. She was inspired by the staff veterinarian and discovered that her passion was to become a Veterinarian herself.

A native of Keene New Hampshire, Dr. Sanders ventured into the world of technology before her admission to Veterinary school. During this time Catherine worked on fulfilling her prerequisite undergraduate coursework to gain admittance to Veterinary school. She spent 5 years at New England Telephone Co. climbing telephone poles and eventually working in management. She will engage anyone who wants to listen to those stories.

Dr. Sanders has over 19 years of experience and has held a variety of positions as a large and small animal Veterinarian before buying Taylor Brook Animal Hospital in the fall of 2009.

Dr. Sanders could not be more proud of, or dedicated to her work as a Veterinarian. She feels it to be one of the highest honors of her life to be entrusted with the well being of the community’s population of pets, a position she takes very seriously every single day. Dr. Sanders has a special interest and expertise in pain management. She holds the values of her profession close to her moral fiber and they guide her in her daily decisions as a veterinarian.

Catherine currently lives in South Portland with her dog Charlie and 2 cats, Eliza and Madeline. She is also helping to raise two beautiful girls, Erin and Elizabeth, who are 6 and 10. Her other passions include fly fishing, gardening, snowshoeing—really anything to do with water or dirt. She owns and is the steward of a 200 year old farm in northern Maine and enjoys spending time there whenever she can get away.
