“Ellen is a visionary leader with a rare combination of business acumen, strategic thinking, insight, empathy, passion, and clinical and emotional intelligence. She deftly cultivates a balance between program operations, organizational management, partner stewardship, and staff mentorship and training,” said Joe Boerio, Catholic Charities Board of Directors President. “Her deep experience with Bay Area nonprofit, governmental, and community partners and keen insight into donor aspirations and client needs make her an exceptional leader for our agency. I am honored to recognize her experience, expertise, and deep, long-term commitment to our agency, clients, employees, and mission.”

Having held a number of roles of increasing responsibility at Catholic Charities, Dr. Hammerle has the insight, breadth, depth, and understanding of client, staff, program, and partner needs vital to the agency’s longevity, impact, growth, and success. She builds effective collaborations, negotiates positive change, brings expertise to oversee organizational development across divisions, and creates effective and scalable growth management for Catholic Charities. Dr. Hammerle plays a pivotal role in securing funding for the agency and will continue to help drive the diversification of revenue sources.

“Catholic Charities has been an integral part of San Francisco for more than 150 years – a true leader and collaborative community partner helping bolster and empower our neighbors when they most need help, solutions, and uplift,” said Dr. Hammerle. “I am pleased to have been a part of that history, developing and evolving our programs as our clients and community’s needs have changed. In my new role, I am eager to continue my contributions to the health and success of our agency, staff, clients, and community.”
