One brick at a time

One brick at a time



Quentin Wilson (President)

Born in 1943, Quentin Wilson made miniature adobe bricks at age 10. At age 27 he started repairing and building full-sized buildings ending up as a licensed construction contractor. Teaching weekend adobe and solar classes all along, he went full time at Northern New Mexico College and established their Adobe Construction Program at 52 and nominally retired at 67.

Mike Lopach (Treasurer)

Mike founded Adobe in Action in 2010 after completing the Adobe Construction Program under Quentin Wilson at Northern NM College. He had experiences working as a volunteer in Mexico with the Franciscan order of the Catholic Church and professionally as a case manager in public housing communities in Seattle that led him to seek out adobe as a possible solution to affordable housing.  Mike spent 8 years in NM and recently returned to the Phoenix area where he continues to be involved with Adobe in Action in his current capacity and actively working toward initiating earthen building projects that will benefit community development.

Mark Zaineddin (Secretary)

At times, perhaps to the chagrin of family, friends, and colleagues, Mark Zaineddin seems to have often taken the road less traveled. Mark has often sought, in small ways, to bring wholeness to a broken world. With an undergraduate degree in International Studies, and graduate degrees in Public Affairs, Middle Eastern Studies, and Divinity, Mark has worked the hallowed halls of Washington DC; taught in Cairo, Egypt; and labored in Northern New Mexico. While at Ghost Ranch, an education and conference center of the Presbyterian Church (U.S.A ), in Abiquiu, NM, Mark, among other things, helped spearhead the creation and implementation of its successful Youth Service Corps. Certainly not a technical expert in the field of earth building, Mark is especially interested in how individuals from across disciplines come to this field and, in doing so, can help promote the greater good.  He now resides and works in North Carolina.
