For Mary Williamson, the summer months are little easier than most. Her boss, Troy Romero , at Turf Grass Farms, Inc. has an open door policy when it comes to Mary's son Zach. Romero grew up in a single parent household and knows the importance of finding time for his family. He loves when Zach accompanies his mother to the office. This is in part due to the fact that Troy is Zach's Big Brother.
