During this era, Hartmann still worked at Atlantic. He was in charge of preparing the club for the 2010 U.S. Mid-Amateur. "The next two years will be a grind but it's good for the game of golf," Hartmann said in early 2009. "It certainly helps amateur golf." Hartmann, did not play much during the year of 2010, according to Newsday, but focused on preparing the club for the event. Shortly thereafter, Hartmann started playing on the senior Met PGA. He had recently turned 50. In 2011, he played the Bacardi Met PGA Senior Championship. The event was held at the par-71 Pine Hollow Club in East Norwich, New York. Hartmann shot rounds of 70 and 69 to win by one. The following year he again had some success, winning the MasterCard Senior Match Play Championship and finishing runner-up at Met PGA Senior Championship. Since 2012, Hartmann has played some Met Senior events but has not had many high results.
