Spencer graduated from Princeton University in 2005 with a degree in History. While at Princeton, he was a member of the heavyweight rowing team and served as the team captain during his senior year. After Princeton, Spencer spent two years working at the Hun School of Princeton, where he was a History teacher and the assistant director of Residential Life. He was also the head coach of the girls rowing program. In the fall of 2007, Spencer returned to Princeton as the assistant coach of the lightweight rowing program and spent two years with that group. In his second year, he helped the Varsity 8+ to championship wins at the Eastern Sprints, the IRA National Championships as well as at the Henley Royal Regatta in England. Spencer transitioned to the heavyweight squad where he was the assistant coach for five years, and he coached four crews to silver medals at the Eastern Sprints and twice had crews earn medals at the IRA National Championships.
Over the past four years, Spencer and the boys' rowing program have continue to build upon the already successful history of rowing at Deerfield Academy. In the spring of 2015, the boys' first varsity 4+ won the NEIRA Championships and followed that up with a bronze medal finish at the US Rowing Youth National Championships. Those results were matched in 2016 with another NEIRA championship in the boys' first varsity 4+ and another 3rd place result at the US Rowing Youth National Championships.
In 2017, the team took a step forward as they won the NEIRA Team Championship, a first for boys at Deerfield. This was accomplished on the strength of championship wins in the boys' first varsity 4+, as well as the third and fourth 4+s. The boys' second 4+ earned a bronze medal to help secure the Team Championship. The boys' first 4+ returned to the US Rowing Youth National Championships and, after three years of finishing 3rd, brought home the national title, the second National Championship for the boys (their first was won in 2012).
2018 saw the boys' rowing team repeat at NEIRA Team Champions with wins in the first, third, and fourth varsity 4+s, to go along with a silver in the second varsity 4+. The first varsity 4+ also repeated as US Rowing Youth National Champions, the third national title for the program.
Spencer resides in New Dorm with his wife, Megan, and their three boys, Caden, Teague and Ryan.
