Senator Marshall is a former Congressman for Kansas’ Big 1st District, a physician, devoted father, grandfather, and husband. As a 5th generation farm kid growing up in Butler County, Dr. Marshall became the first in his family to attend college. After graduating from Butler County Community College, Dr. Marshall received his Bachelor’s degree from Kansas State University and received his Medical Doctorate from the University of Kansas.

Dr. Marshall served in the Army Reserves for seven years and practiced medicine in Great Bend for more than 25 years. As an OB/GYN, Dr. Marshall delivered more than 5,000 babies, giving him a deep appreciation and passion for the sanctity of life and an intimate understanding of the healthcare system. During his time in medicine, Dr. Marshall was more than a physician, he was a business owner signing a paycheck every other week for 25 years for as few as 5 people, but eventually more than 300 people.
