HI there,Karen and everyone--
Regarding NGOs, there ARE quite a lot of them in operation in the DR, many of them "faith based" as you asked.
Compassion International [and several organizations of that type], Amnesty International, CARE,missionary groups have pewrsonnel assigned in the field[especially many Catholic, Adventist, Christian Reformed, Southern and American Baptist, Presbyterian, Episcopal, Methodist,the Mennonite Central Committee, and many,many more]. There are also a number of medical organizations which operate clinics and send mission/work groups on short-term projects.
I've been in the DR as a mission volunteer over the past six years and have met people from a variety of organizations.
FYI:NGO=NONGOVERNMENTAL ORGANIZATION
hOPE THIS HELPS,
