Dr. Frei started her veterinary career at three years of age when she rolled over a toad's foot on her tricycle. The foot healed and the toad lived many years in a planter on her back porch.
Dr. Frei was a registered nurse before completing her veterinary schooling at Tufts University in Boston. After working five years at a local Houston clinic, she opened Southside Place Animal Hospital in 1994. She has many pets, including four cats (two are blind), two dogs, three lizards, four turtles and about thirty fish. She also has a lively daughter that just started at Texas A & M University. Their favorite hobbies to do together are camping, hiking and animal watching.
