Our staff’s goal is to provide excellent patient care and useful client education.  The Front Desk staff (Reception) will book your appointments, answer your initial questions, and check you in and out.  Our Exam Room Assistants and Veterinary Technicians will take a brief history to find out what concerns you may have regarding your pet and his or her care.  They then help the doctors and perform many procedures such as toe nail trims, blood draws and Xrays. When your pet has to be hospitalized for surgery or medical care the technicians check their vital signs throughout the day, administer medications and keep them comfortable. Our staff  are experienced, trained and knowledgeable and THEY LOVE PETS!

Pamela J Mueller DVM, Ph.D., CCRT (Certified Canine Rehabilitation Therapist) 

Dr. Pamela (PJ) Mueller grew up in Chester County, surrounded by a veritable zoo of pets that included at various times dogs, cats, chickens, rabbits, mice, rats, guinea pigs, hamsters, gerbils, finches, parakeets, turtles, fish, ponies, and horses. She fled the East Coast to attend college at Reed in Portland, OR, where she studied (of course) Biology, learned calligraphy and climbed mountains. Following college she lived in Germany and Belgium (becoming proficient in French and German), then fulfilled a childhood dream to work in Africa by spending three years in the rainforest of the Congo, teaching high school science. Upon returning to the US, Dr. Mueller worked on animal-powered farms (using oxen and horses to plow) in Michigan and Alabama to prepare further for a career with animals. She then completed both a Ph.D. in Animal Nutrition and a Doctor of Veterinary Medicine (DVM) at Cornell University in Ithaca NY (2008).  Dr. Mueller has practiced small animal medicine at clinics in North Carolina, Bethlehem PA, and Philadelphia.  She is certified in Canine Rehabilitation (physical therapy) and takes a special interest in both athletic and geriatric dogs. Currently, she lives in West Chester PA with two border collies with whom she competes in Agility and Sheepdog Trials across the United States. Her "spare dog" is a terrier named Tick who excels at sleeping. If you ask her for a memorable achievement she will tell you that she can train chickens, a feat that once landed her a spot on TVs very silly game show "The Weakest Link".
