Hi Terry,
CIMA Guanacaste currently has an ER and is also equipped with diagnostic testing equipment like X-rays, CT scans, and ultrasound. You can also see a GP there.
The eventual plan is to have several specialists and be able to perform major surgeries there. A big target market will be medical tourists who come down to CR for surgery and stay at an on-site hotel during recovery.
Clinica Biblica has a small clinic across the street. But really all they do is lab testing and doctor visits with a GP.
The largest hospital in this area is the public hospital in Liberia. They treat quite a bit but very serious cases they send to San Jose.

For the Guanacaste branches of CIMA and Biblica you can call their main line in San Jose and talk to somebody there.
