Earl Maxwell

Board Treasurer

Since 2007, Earl Maxwell has served as the CEO of St. David’s Foundation. The Foundation is a nonprofit that improves health and healthcare for Central Texans. Of the Foundation’s more than $40 million budget, money is granted to community-based organizations that provide primary and special healthcare for the uninsured, mental health services, services for older adults, healthy living and wellness, and research and education. The Foundation also provides dental care to Title I schools in the Greater Austin area. The Foundation, in partnership with a for-profit company, owns the seven St. David’s hospitals in Central Texas, which provide millions of dollars of care each year for the uninsured in St. David’s hospitals.
Prior to stepping into the St. David’s role, Earl was the leading partner of Maxwell Locke & Ritter LLP, Austin’s largest locally owned and managed accounting and consulting firm. He grew up in Houston and attended the University of Houston where he received his Bachelor of Business in Accounting in 1976.

Earl is the author of Service Prosperity and Sanity — Positioning the Professional Service Firm for the Future. His experience includes 31 years in public accounting, including 14 years with Deloitte & Touche and its predecessor Deloitte Haskins & Sells.

Earl’s innovative, non-traditional experience grew out of the process he and the partners of Maxwell Locke & Ritter followed as they established and built a different type of firm…..a firm dedicated to serving people. His work at the St. David’s Foundation is a logical extension of his previous experience.

Earl has spent most of his time in three areas; family, community and business. He has been able to merge these interests by helping to establish a family-friendly workplace and working in the community to support various educational and health and human services programs. He is proudest of his partnership with his wife in raising their two sons. He strives to provide a work environment that is committed to balancing work, life and the community.
