Dr. Chris Homer

Dr. Chris graduated in 1992 from the University in Guelph in Ontario, Canada. Chris has been passionate about dairies and dairy medicine since he spent summers in his teenage years on his uncles dairy farm. Chris has many years of experience with cows from Alberta, Canada to Garrett county, Maryland before coming to centre county Pennsylvania and making it his home. He is no stranger to the late nights and long days of veterinary medicine, but loves cows and veterinary medicine. Chris loves reproductive medicine, embryo transfer in cows, AI in horses, dairy production medicine, surgical cases, herd health and sick animal work with cows. But does include dog, cat, goats, pigs, horses, deer and any other animal with fur in his work.

Dr. Lucas DeFiores


 Dr. Lucas DeFiores joined Straley’s in July, 2016. Dr. Lucas is a recent graduate of Cornell University College of Veterinary Medicine. Lucas grew up in New York State and started riding horses when he was young. Then while in high school he took a summer job on a dairy farm….that was enough to convince him very early that he wanted to become a large animal veterinarian and work with cows and horses. He concentrated on Agricultural and Animal Science even before Cornell and has been learning to work with farm animals ever since. Lucas is particularly interested in reproduction both in cows and horses, and brings lots of experience and enthusiasm to his job.



 Sue Homer 

Sue Homer moved to Centre County Pennsylvania in 2002.  In 2003 Sue joined the clinic and managed it until 2012 when Sue, Chris and Dr. Kathleen Rhoads purchased the large animal mobile practice from Dr. John Shapira. In Canada Sue was an operations manager for a large retail chain and lived in the city of Toronto, Canada. Although Sue spent most of her life in downtown Toronto she learned to milk cows in Maryland and love the rural lifestyle. Sue is energetic and enthusiastic about the work that Straley’s does and wants the best for the Straley Large Animal team and clients and especially the animals they care for.
