Hi William,
I am guessing you mean Playa Matapalo, near Quepos (there are actually several Matapalos, but no Montopolas)? If that is the case I imagine that is a lightly populated area, you may need to travel to Quepos or Manuel Antonio to find an English speaking church. Join the Southern Zone’s Facebook page. The members live in the area and will be able to help you out – https://www.facebook.com/groups/707768359266826/search/?query=matapalo.
Best of luck,
