The Gonzaga College High School Chapter of Medical Missionaries was the first Chapter, formed in 2009. The Chapter has raised funds for Medical Missionaries on several occasions, holding bake sales and car washes and taking collections on special days at the school.

The Gonzaga Chapter responded quickly to the earthquake in Haiti (January 12, 2010), collecting more than $1,000 in donations from students and faculty for earthquake relief. The students also held a drive to collect packets of soap, washcloths, toothpaste, and toothbrushes ("hygiene packets").  In two weeks, they collected more than 3,000 packets, filling 100 plastic bags. The bags were brought to Medical Missionaries' warehouse in Bristow, VA, on March 20 and uloaded with the help of the Buffalo Soldiers Motorcycle Club. (See the story of that cooperative work.).  The hygiene resources became an important part of a hygiene program that Medical Missionaries instituted in Thomassique, Haiti.
