Mark Kirwin and his brother Stephen traveled to Phnom Penh, Cambodia in May 2005 to see Cambodia after the tsunami disaster relief project to help the stranded Moken with fishing boats and food staples was completed in Thailand. Confronted with endemic poverty and a heartbreaking trip to a local children's home for abandoned children near Phnom Phen he ended up with more "KIRF work". Being leary of the multitude of real and not-so-real non-profits in Cambodia subsisting on the "NGO economy" the brothers quickly decided to personally evaluate local needs and deliver supplies themselves. It was not hard to find heart break and poverty among the wide boulevards and parks of the French colonial influenced capital city of Cambodia.

KIRF ended up purchasing and delivering building supplies and food staples to a home for street children outside of Phenom Phen called the Lighthouse Orphanage. He was assisted in the effort by his brother Stephen who had be-friended local a humanitarian and café owner in the country's capital city on an earlier visit. With the assistance of an informal aid network of locals, KIRF purchased needed building supplies at the local rate for the Lighthouse Orphanage. With local assistance KIRF delivered the lumber efficiently on a local motor bike taxi which allowed the Lighthouse Orphanage to complete the construction of several classrooms soon after. His brother stayed behind in Cambodia and saw to it that all the KIRF purchased supplies were used as intended.

In addition to Lighthouse Orphanage project, the brothers with assistance of several local humanitarians, distrubuted food packages to homeless families safely one evening at a central park crowded with families sleeping outside in Phnom Penh. Before leaving Cambodia, they braved the hazards of exploring the trails around an ancient Buddhist temple by going for a morning run in the countryside--a beautiful verdant land that is still littered with deadly un-exploded land mines and still suffering profundly from the Pol Pot regime's war of terror against their own people many years ago.
