Dr. Carla Douple

Dr. Carla Douple grew up right here in Lancaster County on a local “farmette”. She began to develop her love for all creatures great and small early in life as she “mothered” the various strays and back yard pets.

During summer breaks from Messiah College, Dr. Douple worked at Landisville Animal Hospital as a veterinary assistant. She then graduated with a bachelor of science in biology and a horticulture minor. In 1998, Dr. Douple graduated from The Ohio State University School of Veterinary Medicine. “When I was ready to come back to Lancaster County, I interviewed at several local practices, but Landisville Animal Hospital was where I belonged and I am here to stay.”

Dr. Andy Keller

Dr. Keller was born and raised in Lancaster County and attended Conestoga Valley High School.

His special interests include orthopedic and soft tissue surgery.

He graduated from Houghton College with a degree in Biology and a minor in Chemistry, and attended The Ohio State University School of Veterinary Medicine, graduating in 2014. He spent a year and a half practicing in Elizabethtown, and joined the Landisville Animal Hospital team in the summer of 2015.

He and his wife, Lenore, their daughter Liesel and son Warren live in Elizabethtown with their cat Lou. He and Lenore have been married since 2010 and welcomed Liesel in September of 2015 and Warren in November of 2017. Dr. Keller enjoys roasting coffee, rowing, and cooking.
