Mark Smith of IMPACT next to water tank

Mark Smith

Executive Director

Mark’s passion for water projects took root in the early 1980s, when he was provided the opportunity to build a sustainable water system in a remote Waorani village in the Amazon jungle of Ecuador. Accompanying him on this trip were nine men from the non-denominational church that Mark was pastoring in San Antonio, Texas. Struck by the dramatic change that the project produced in the life of the village, and in the lives of the volunteers, Mark sought out other opportunities to serve. He would lead more than a dozen water projects in the years that followed, travelling as far as Africa, where he helped build a well for an orphanage. Burdened by the need for clean water in remote villages, and passionate to help men grow in their faith, Mark transitioned from his pastoral position and began leading water projects full-time in 2008. Since then, Mark has directed over 24 projects to needy villages in Honduras.

Gustavo at the honduras/el zapote/boone planta water project

Gustavo Lepe


Gustavo is a Tegucigalpa native and serves as IMPACT’s local translator, helping to facilitate meaningful interaction between the Honduran villagers and IMPACT’s American teams. Gustavo’s sincere love for his people creates a foundation upon which IMPACT volunteers can build relationships and minister to the villagers. Gustavo serves a variety of roles from day to day: Some days as a mentor, while playing volleyball with local children, and other days as a sympathetic ear, while standing bedside with a grieving family as a loved one passes away. When IMPACT’s U.S. teams return home, Gustavo nurtures the villagers’ spiritual growth and pursues other humanitarian projects on Honduras’ impoverished Mosquito Coast. Gustavo holds a degree in Business from John Brown University in Arkansas and a MBA from Universidad Francisco Marroqui MBA School in Guatemala City, but returned to his native Honduras to love and serve the marginalized people of theses remote villages.

Marisabel Espinal

Children’s Outreach Coordinator

Marisabel is a beloved community liaison and IMPACT’s Children’s Outreach Coordinator. Mari conducts Vacation Bible School in every village that IMPACT serves, providing spiritual training to children who have had little or no exposure to the Bible. Life is hard in these villages, and children as young as four-years old spend much of their time gathering water, working in the fields, and babysitting. For these children, Vacation Bible School is a celebration akin to Christmas or a birthday party. IMPACT’s U.S. volunteers also pitch in, connecting with the village’s children on a heart level, and providing village men with a better model of fatherhood. Mari’s role in this work cannot be overstated.

Operations Volunteers

David Parker

David has been involved in the world of advertising and marketing as a creative director for over 30 years.  In April of 2009, a friend convinced him to join a team of IMPACT volunteers working on a water project in Honduras.  After spending a week in a village in the remote mountains helping build a system to bring clean water to the homes of the village families, he was hooked.  David has volunteered on two subsequent projects in Honduras and serves on the IMPACT Operations Team, assisting with fund raising efforts and project management.  He says, “The magic moment of being involved with IMPACT is when we turn on the faucet for the first time and clean water pours out.  The look in the eyes of the women and children, knowing that they won’t have to spend hours everyday searching for water and that water-related sickness will no longer be a constant threat, is worth every dollar and hour we donate.”
