Dr. Holland is the owner and founder of Circle of Life Veterinary Clinic. She graduated from the University of Rochester in 1983 with a Bachelor of Science degree in Microbiology, and worked for several years at Strong Memorial Hospital at the University of Rochester, and then at the Wistar Institute, where she did research into melanoma. She then went on to earn a Masters of Laboratory Animal Science from Hahnemann University in 1992. She then worked in the field of cytotherapeutics (artificial organs).

Dr. Holland then decided to take her pursuit of science in a different direction, combining it with her lifelong love for animals, and enrolled in veterinary school. In 1998 she graduated from University of Pennsylvania with the degree of Veterinary Medical Doctor. She has been practicing since, and is particularly interested in neurology and feline medicine.

Dr. Holland lives in upper Bucks County with her husband and an ever-changing household full of rescue, special-needs, and foster cats and dogs. She runs daily, both to train for the competitive racing she enjoys and to maintain her own inner balance. Though she loves all animals, she has a particular fondness for beagles, and there will always be a special place in her heart for orange cats (if you've read David's story, you'll know why.)
