Sara Castle

Director, Business Operations

Prior to co-founding iResearch Atlanta, Ms. Castle spent most of her career as a clinical research consultant, living in New England and working for Biotech and Pharmaceutical companies. There she focused on implementing new electronic data capture (EDC) tools and educating users and new research personnel on ICH, GCP compliance and CFR guidelines.
