Dean Richardson, David Galligan, Virginia Reef, Corinne Sweeney, and Raymond Sweeney. Richardson is well known in racing circles for his attempts to save fan favorite Barbaro, who fell victim to laminitis following a severe injury to his right hind leg in the 2006 Preakness. Richardson, who has served as Chief of Large Animal Surgery at New Bolton, has developed the use of locking compression plates in equine surgery, advanced imaging technology to improve surgical outcomes, and refined procedures to reduce infection after surgery. Besides his considerable respect in surgical practice, he has garnered numerous awards and is well known as a mentor to veterinary students at the school. Earlier this year, Richardson was injured seriously in a riding accident necessitating surgery. Sweeney is an internal medicine specialist who also served as associate dean for New Bolton Center. She has published peer-reviewed research on a wide range of medical topics from infectious disease to EIPH and has served as chair of the Association for Racing Commissioners International.
