About Alison

Dr. Manchester got into veterinary medicine watching her parents work as physicians and having an extreme love and appreciation for animals. She does clinically relevant research to improve understanding of diseases that impact the quality of life of our canine and feline companions. Particularly, she’s interested in chronic gastrointestinal conditions. This interest was sparked by her Celiac diagnosis in 2009, as well as inspiration studying E. coli-associated granulomatous colitis with Dr. Kenny Simpson at Cornell University. She loves working with clients, students, and fellow clinicians, and feels lucky to be part of the CSU community.
