For over 40 years, Nonantum Veterinary Clinic has been a trusted part of the community, caring for pets and the people who love them with heartfelt compassion, honest guidance, and a deep sense of integrity. From Chester County to northern Delaware and nearby Maryland, families know they can count on us to treat every pet like one of our own.
Lifelong health starts with routine care. Our personalized wellness visits help us get to know your pet inside and out, from nose to tail. With tailored vaccinations, parasite prevention, nutritional counseling, and early detection screenings, we keep your dog or cat feeling their best at every age and stage.
We offer a wide range of soft tissue and orthopedic procedures right here in our clinic, conducted with skill, compassion, and meticulous attention to safety. While our own veterinarians are highly skilled, we also have a traveling surgeon who performs TPLOs, MPLs, and fracture repairs.
We believe healing works best when we treat the whole pet. Our integrative therapy services, including chiropractic care, acupuncture, and physical rehabilitation, offer gentle, noninvasive support for pets living with pain, recovering from injury, or simply needing a little extra help as they age.
Dr. Colleen Stewart received her B.S. from Penn State University in Animal Sciences. She then worked for New Bolton Center’s dairy farm for a year and a half before starting veterinary school at Ross University on St. Kitts.
After a year at Ross, she transferred to a second year at the University of Penn School of Vet Medicine. In 2017, she worked as a mixed animal vet in Lancaster before transitioning to small animal medicine here at Nonantum in 2020.
Dr. Stewart grew up around the corner in New London, PA. She enjoys being outdoors, playing sports, creating artwork, and spending time with family and friends. She currently resides in Cochranville with her husband Zach, sons J.D and Liam, and pit mixes Turbo and Bob.
Dr. Charlotte Fagraeus has been a veterinarian in the local area for many years and found a home at Nonantum in 2020. She has previously been a practice owner but now gladly can focus her attention on her patients rather than running a practice! She is the proud single mom of two teenagers and a Scottish Terrier. She was born in Stockholm, Sweden and likes to visit there often, alternating with going on cruises. Doing New York Times crosswords and crafting are other favorites.
Dr. Palmer’s family has been taking their pets to Nonantum since 1988. He joined Nonantum Veterinary Clinic in 2023 after graduating from the University of Pennsylvania School of Veterinary Medicine as a second career student. With a background rooted in education and animal care, he brings a calm, practical approach to each appointment — whether that means building trust with a nervous patient or walking an owner step-by-step through a treatment plan.
His goal is always the same: to help clients feel informed, heard, and confident in the decisions they make for their pets. He’s also known around the clinic for being a reliable treat-dispensing machine when the situation calls for it.
When he’s not in the exam room, Dr. Palmer enjoys backpacking with his son and their dog, usually somewhere far enough into the woods that cell service can’t find them.
During his long general veterinary career, many years practicing with Dr. Debby Roberts, Dr. Manning has gained the most satisfaction from doing surgery. He continues to operate, now part time, at Nonantum.
