About us

La Merced is a 501C3 nonprofit organization comprised of volunteer health care workers, business and legal professionals, engineers, contractors, educators, homemakers and students who have united for the common goal of helping our neighbors abroad. Currently, La Merced is focusing on Nicaragua.

Although La Merced developed out of the Church, we now are independent. We do, however, continue to work with the Church on common goals and endeavors.

La Merced is now partnered with University of Maryland Eastern Shore (UMES). Through this formal relationship, the organizations work hand-in-hand to seek funding and provide manpower for the medical missions.   Pharmacy students from UMES now serve as integral parts of the La Merced team.

If you are interested in getting involved, we would be more than happy to find voluntary work for you in Nicaragua or stateside.
