Mary Kathleen Mahan and Family Endowed Fund

Mary Mahan

The Mahan Family are long-time residents of the State of Oklahoma who have served the public through the military, education, public policy, public service and public health. Mary Kathleen (Kathy) Mahan, who earned two degrees from The University of Oklahoma, used her Master's in Education to promote and enhance the quality of life for all Americans. Kathy won many awards for her service, including the Commissioner's Citation, the Social Security Administration's highest honor award. The donor wishes to endow and award to support, encourage and inspire students to make history through public service, as did many family members and Kathy, in particular. It is the families' hope that the awardee will have a deep comprehension and understanding of the past, current, and future American history and the positive impact that history has made in the world, thus honoring Kathy and the families through the students at The University of Oklahoma.

Those in the family, when asked about their hopes from students who receive this scholarship would respond, they hope they will be inspired, be engaged, and improve the quality of life for all Americans. They also sincerely hope that they will continue the work of Kathleen.

Family Legacy:

The Mahan and Soderquist family and their extended Stallman, Shook, Adams, Allgood, Cartwright, and Kelly families have a legacy of public service, working at all civic levels in local, state, and federal government in addition to military service, which began during the Civil War. Members of their families continued to serve in the 20th century Korean Conflict and Vietnam War as well. As Vietnam War veterans, continued their service to veterans and advocacy for veteran's health care through their work within the Veteran's Hospital in Muskogee, OK during the 1990s to 2012.

Numerous family members became teachers, establishing and improving educational systems as the United States grew and expanded during the 1800s and 1900s. Areas of education taught by family members have included elementary and secondary education in public schools, a partnership with NASA to teach students about the Space Program of the 1960's and nursing and business courses in college. Five family members in education received both Bachelor's and Master's degrees, along with three who persuid post graduate degrees towards PhD's.

Health care is valued by the Mahan and Soderquist family and extended families, and medical care has been advanced by their own work treating and caring for patients during war, in homes, community settings, hospitals, those needing long and extended nursing care, and hospice and end of life comfort. Family members especially have moved health care forward as participants in research studies. As new methods of treatments, medications, and health knowledge are rapidly known, these have been tried and tested and embraced by their families early, contributing to medical knowledge. Emphasis on Public Health has been valued, improving the health quality of American Lives. 

Agriculture and nutrition, since the 1800's has been a predominant way of life for our families. Commitment from generation to generation has always been to grow more food to feed more people within the United States and worldwide. Dedicated to improving growing techniques, land management, and contributing to the distribution of food, family members pursue advanced University research and give priority to improving the quality of food produced.
