A long standing tradition for mission teams at FPC has been annual travel to Piedras Negras. The FPC Adult Mexico Mission Team began in 1992 with five members teaming up with FPC of Florence, SC. For the next five years, the team built three-room homes out of cinder blocks, mortar, and concrete for needy families in Mexico. Beginning in 1998, First Presbyterian Church formed its own construction team led by Howard Barnard and George Lack (construction foreman).
In 2000, medical teams from FPC joined the annual week-long mission trip to provide much needed medical treatment for the families in Mexico. That same year, John Schlatter assumed the position of construction foreman. Then in 2001, the mission added an additional week for the construction of a second home.
After the summer of 2011, FPC will have built 25 homes in Piedras Negras, Mexico with more that 425 members and friends of FPC participating in the construction of these homes through the ministry of Constructores Para Cristo.
