Lorraine Stiehl

Lorraine Stiehl

Chief Executive Officer

Lorraine Stiehl was named CEO of the American Liver Foundation in January 2021. A successful non-profit leader for over three decades, Ms. Stiehl serves on the National Institute for Diabetes and Digestive and Kidney Diseases (NIDDK) Advisory Board at the National Institutes of Health (NIH). As a public health leader at both the state and federal levels, Ms. Stiehl advocates for strengthening disease prevention efforts, and supporting patients battling chronic diseases and their healthcare providers.

Ms. Stiehl worked both professionally and as a national volunteer leader for numerous non-profits, including the Juvenile Diabetes Research Foundation (JDRF) where she contributed to the organization’s growth from $6 million to over $200 million – earning top honors as “National Staff Member of the Year” (1992) and “National Volunteer of the Year” (2010). Ms. Stiehl also worked for nearly two decades at the University of California, San Francisco (UCSF), providing leadership in fundraising development, marketing and communications and clinical trial recruitment.

Through her family’s consulting firm, StiehlWorks, Lorraine provided marketing, communications, fundraising and advocacy support to dozens of national non-profits and medical research organizations. In 2017, Lorraine and co-author, Dr. Nicole Johnson (Miss America 1999), published, “What To Do When Your Partner Has Diabetes: A Survival Guide.”

As a lifelong caregiver, Ms. Stiehl knows first-hand how chronic disease impacts families. Her husband Chris has been living with an autoimmune disease for more than 60 years and an organ transplant for 12 years. Highly motivated to support deserving non-profit organizations, Ms. Stiehl has raised millions of charitable dollars including funds she has generated through dozens of half-marathons and cycling events.
