CDF Staff

Children’s Diabetes Foundation Staff

The Children’s Diabetes Foundation has the right team to make big things happen. See more about our staff below, and feel free to contact them with any questions or concerns!

Dana Davis – Executive Director

Dana Davis has spent most of her life as an activist, philanthropist and educator, fueled in part through her own personal struggle with Type 1 Diabetes with which she was diagnosed at age seven. She has been at the forefront of the renowned Children’s Diabetes Foundation.Together with her family, she has raised over $75 million for diabetes research and wellness.

After graduating from the University of Southern California with a Master’s Degree in Education, Dana began her career as an elementary school teacher. During these early teaching years, she became plagued by Diabetes-related foot problems, exacerbated by long hours spent on her feet in the classroom. Throughout the next twelve years, she would undergo eight corrective foot surgeries until ultimately, she was advised to discontinue teaching and adopt a critical foot care program. Her disillusionment with the search for luxurious yet comfortable shoes inspired a desire to develop her own line.

In addition to being the Executive Director at CDF, Dana continues philanthropic efforts through her long involvement with The Mattel Children’s Hospital at UCLA, and sits on the board of The Nancy Davis Center Without Walls and the Children’s Diabetes Foundation.
