  The Ann Rehan Goebel Foundation was established to honor the life of Ann Rehan Goebel, MD, a Sioux City pediatrician who passed away from a brave battle with cancer on February 20, 2023.

  Ann loved being a doctor and helping people – and she did it with her own brand of care and personality. She wove a deeply human element into her medical practice, creating unforgettable connections with her patients and colleagues.

  When Ann passed away from cancer in 2023, her family and friends felt like her life’s work wasn’t done yet. That’s how the Ann Rehan Goebel Foundation was formed. Our annual Science, Technology, Engineering and Mathematics (STEM) scholarship is inspired by Ann’s passion for the field and sharing her gifts with others. By helping students realize these similar aspirations, we will keep Ann’s spirit alive.

  This 5K helps support the ARG Foundation mission locally.
