“I‘m so grateful to Sutter Health. I’ve never even thought about retirement.” — Elena Griffing

90-year-old employee celebrates 70 years at Sutter Health
Most days of the week, 90-year-old Elena Griffing can be found clicking down the hallways of Sutter Health’s Alta Bates Summit Medical Center, where she has worked in one capacity or another since 1946. Seventy years later—after working in pathology, endocrinology, the burn unit, and finally, patient relations—she’s still on the job.
Sutter employees partner together during wildfire crisis
Nearly 150,000 acres burned. More than 1,000 homes destroyed. Thousands evacuated. The devastating 2015 wildfires in the Northern California communities throughout Amador, Calaveras, Lake, Napa and Sonoma counties impacted many in our Sutter Health family who live and work in the communities impacted by the flames. They teamed up in extraordinary ways in this time of crisis to support our patients, each other and our communities.
Team Spotlight
We have been on a journey to redesign our operations and organizational structure so that we can continually improve and better meet the needs of our more than 3 million patients. We’d like to introduce you to some of the talented individuals who led us through this continued reinvention in 2015.
Stephen Lockhart, M.D., Ph.D. Sutter Health’s Chief Medical Officer
Steve Lockhart, M.D., Ph.D., found his calling in health care at an early age, after his beloved mother suffered a brain aneurysm. The neurosurgeon caring for her took the time to explain the procedures to Dr. Lockhart—an experience that made a huge impression on him, particularly because he was so close to his mom, who raised him as a single parent. He knew he wanted to be like the doctor who cared for her. Today, Dr. Lockhart oversees patient-care quality and safety, research and education for Sutter Health as our chief medical officer. Before spending the past decade in senior leadership positions within Sutter Health, Dr. Lockhart practiced as an anesthesiologist for 25 years. A lifelong outdoorsman and passionate advocate for the national parks, Dr. Lockhart spends his time outside of the clinic walls serving on boards of organizations that promote environmental stewardship and youth mentorship, including NatureBridge, the National Parks Conversation Association and Recreational Equipment Inc. In 2009, President Obama’s Champions of Change program recognized Dr. Lockhart and 13 others as the Next Generation of Environmental Conservationists. He regularly volunteers for humanitarian causes and organizations he feels passionate about. In fact, Dr. Lockhart, his wife, Karen, and daughter, Anna, lived in Chile for six months while volunteering for an organization that provides medical care for children recovering from burns.
Don Wreden, M.D., Senior Vice President for Patient Experience
A big dish of South Texas dirt sits on the desk of Don Wreden, M.D. The dirt provides a daily reminder of Dr. Wreden’s farming roots—and the unique ways that it is strangely similar to his leadership position at Sutter Health. In his role, Dr. Wreden works to ensure that all of our patients experience consistently high-value care wherever they go with the network. He says this cultivates “fertile ground” where doctors and employees can collaborate on promising new approaches to medical care, in critical areas such as chronic illness, palliative care and end-of-life care. The task isn’t so very different from farming—the occupation of his German immigrant father when he was growing up near the Gulf of Mexico. When faced with external challenges—whether boll weevils, drought or hurricane—Dr. Wreden says neighboring farmers pulled together, supporting and learning from each other through hardship and success, and demonstrating incredible resourcefulness, resilience and community spirit in the process. Dr. Wreden practiced medicine for 16 years as a board-certified general internist and hospitalist before assuming a variety of leadership positions within Sutter Health. The sense of community, working with others, and learning to trust and delegate tasks to his team—crucial to providing health care—are values that were firmly instilled in him as a farmer’s son.
Jill Ragsdale, Chief People and Culture Officer
As our chief people and culture officer, Jill leads the programs that empower nearly 50,000 Sutter Health employees and 5,000 physicians to provide health care that is ranked top in the nation.

Chris Waugh, Chief Innovation Officer
As Sutter Health’s first chief innovation officer, Chris serves as the “front door” through which external innovators connect with Sutter Health and internal innovators can present their ideas on ways to help us improve how we deliver care to our patients. With more than 10 years of entrepreneurial leadership at IDEO—a globally regarded Bay Area design and innovation consulting firm whose clients include Nike, Google and the CDC—Chris brings unique and human-centered approaches to benefit patients across our network.

Anna Kiger, R.N., Chief Nursing Officer
Nurses. They care, comfort and heal. They teach, advocate and guide. Ask any patient—or any doctor—and they’ll tell you the critical role nurses play in a patient’s health care experience. Simply put: We could not provide quality, compassionate care without them. Nurses are so essential to patient care that Sutter Health has created a new chief nurse officer position. Anna Kiger, DNP, D.Sc, MBA, R.N, joined Sutter Health in 2015 to advance the safe, high-quality and high-value care provided by nurses, professional and technical staff for our network’s 3 million patients. Kiger has more than 30 years of clinical experience and more than 20 years of health care executive leadership experience, including serving as system chief nurse officer and vice president of patient care services at Tenet Healthcare.

Sarah Krevans Named CEO After Pat Fry’s Retirement
As a young adult, Sutter Health’s Sarah Krevans held entry-level jobs in care facilities for people with severe mental illnesses and the frail elderly. These experiences had such a profound impact on her that she decided to devote her career to improving a health care system that she felt was in disrepair. After nearly 30 years of strong leadership and a clear vision for making health care better—including 16 years as an executive at Sutter Health—Krevans became our new president and CEO in January 2016, succeeding Pat Fry, who retired after 33 years of dedicated service. Fry began his career at Sutter Health as an administrative fellow in 1982, working his way up region and division executive leadership positions before becoming CEO in 2005. Under his leadership, Sutter Health earned innumerable state and national distinctions for clinical excellence and patient safety, consistently ranking among top performing physician organizations and hospitals in the state and nation. He led multiple initiatives to deliver quality care and service more efficiently, including Sutter Health’s acclaimed Advanced Illnesses Management (AIM) program. Among his other notable achievements, Fry helped create the Sutter Medical Network, which unites Sutter’s 5,000 aligned and affiliated physicians around common quality commitments; My Health Online; and Sutter Health Plus. “Pat leaves an incredible legacy of achievement and decisive strategies to improve quality, access and affordability. Under his leadership, Sutter Health became a national leader in clinical quality and greatly expanded community access to health care in big cities and small towns throughout Northern California.” —Sutter Health Board Chair Todd Smith, M.D

quote marks“Sarah is a respected, community-minded leader who is exceptionally well qualified to assume the role of Sutter Health’s chief executive.” — Sutter Health Board Chair Todd Smith, M.D.
