The mission of the William Stretesky Foundation is to enhance and benefit the Sedgwick County Community and its residents. The foundation was established by William Stretesky through his last will and testament with the primary goal of supporting the community where he spent his life. The foundation generates grant funds through cash leasing its real estate holdings, following Stretesky's wish to use the bulk of his estate for the betterment of Sedgwick County and its residents.
The broad goals of the William Stretesky Foundation's grant program are to support various initiatives that contribute to the improvement and enrichment of the Sedgick County community and its residents. The specific causes supported by the grant program include Arts and Culture, Education, Community Development, Medical & Emergency services, Historical Preservation, and Operating Expenses for initiatives within these categories. The foundation fulfills its mission by funding projects and programs that align with these focus areas, thereby continuing William Stretesky's legacy of giving back to his extended family—the residents of Sedgwick County.
