Dr. Sexton has served as Co-Director of the Advanced New York State Certificate Program in Health Care Management since its inception in 1988. Through this program, students in health care take MBA courses in the College of Business and MBA students take courses in health care management as they earn the certificate. The program is designed to improve the quality of health care management and to forge a strong tie between the Health Sciences Center and the West Campus. Dr. Sexton has taught courses in outcome measures and health care models in the certificate program. He also teaches courses in statistics and management science in the College of Business.
