Brian Green is a founder of Christian Health Associates and at the time of his sabbatical had worked as its executive director for 18 years. Under his guidance, CHA grew to include a clinic and counseling center, a program that matches volunteer medical professionals with under-insured Alaskans, public school-based clinics, oral health care, medical missions to developing countries and other health programs. His sabbatical provided time to focus on prayer, reading and reflection needed to help prepare him to continue as CHA’s leader. All four founders were still with the organization nearly 30 years after it was formed. In 2023, Green announced a plan to retire by 2024.
