He was one of the most esteemed citizens of Cleveland County and had held public office of responsibility and trust and had acquitted himself with credit and to the advantage of the people.

Obtaining sufficient funds, he entered the University of Arkansas in Little Rock, from which he was graduated in 1891 with a Doctor of Medicine Degree. He practiced his profession for one year in Rison, then practiced in Thornton for four years.
