Reuben was married to Meghan Williams in 2010, and they have two daughters, Clara Aida and Vivien Leigh.  The family lives in Baltimore County, Maryland, USA, with a menagerie of pets (Ash, Millie, Chewbacca, Ivy,   and a school of guppies).  Fortunately, for this animal filled household, Meghan is a veterinarian.  Reuben is the eldest son of Rick and Cathy Johnston, who live in Texas, and has three other siblings (Justin, Judith, and Michael). 

Reuben enjoys spending time with Meghan, Clara, Vivien, and the household zoo, as well as family and friends.  He enjoys rock climbing, visiting national parks, backpacking, competing in triathlons, cycling (road & off-road), running, and watching popular sports.  Reuben is also a science fiction and fantasy fan, and will occasionally play a game of Magic the Gathering.
