He had a brief internship in Memphis, Tennessee, before setting up a medical practice back in Kentucky.  In September 1917 he was instructed to report in person to the Army Medical School in Washington D.C. before being posted overseas to join the B.E.F.  On 25th April 1918 he was serving with the 112th Field Ambulance, when he was ordered to report to the Assistant Director of Medical Services, 11th (Northern) Division. The A.D.M.S. posted him to serve with the 35th Field Ambulance.
