Do I have to speak Spanish?

All medical volunteers and trainers/mentors must speak at least intermediate level Spanish. Only exceptions: OB/GYNs surgeons, and a few specialists.
Intermediate Spanish is defined as the ability to:
• Speak, read and write in the present, past (preterit and imperfect), and future tenses (ir + a + infinitive construction sufficient).
• Understand everything said by Spanish speakers, conversing at a rapid pace.
• Interview, examine and treat Spanish-speaking patients without an interpreter.
