Marcus and Alison were commended to the work in Mexico in 1996, arriving in Puerto Vallarta with their children Isaac and Madeleine. In 1997 a new work commenced in Tepic, Nayarit, about 160 kms north of Puerto Vallarta where they were living at the time. The assembly in Tepic was established in January 1999. Two other children were born in Mexico: Samuel and Evelyn. They began working in Santiago Ixcuintla, Nayarit, about an hour north of Tepic in 2005 along with James and Nelly Dyck. There is a small assembly functioning there now as well. In December 2010, they moved to Hermosillo, Sonora to help in the assembly there. Marcus travels some around the country, mainly to help in the teaching of the Word of God.
