Harmeling attended Princeton University. He was on the golf team. He later told the Sun Journal, "I played pretty solid. I didn't win any tournaments in college, which is kind of disappointing. We had good teams, but nothing to write home about."[2]
Professional career
In 2012, Harmeling turned professional. The following year, Harmeling won two state opens in New England. In June, won the Massachusetts Open. He donated his $10,000 winners cheque to the survivors of the recent Boston Marathon bombing. Later in the summer he also won the Maine Open, defeating Jesse Spiers and Geoffrey Sisk by one shot.[2]
