About Niche Marketing (Spanish Only or both)

I have a medical practice where about 80% of patients are from Hispanic community. I advertise in weekly Spanish magazine and have been receiving steady flow of new pts. Most of my pts. are limited bilingual and prefers to speak Spanish whenever possible. I have a rather inactive Facebook account in English and now I am thinking of revitalizing it. Should I create a separate Facebook page in Spanish as well? BTW, my Spanish is very limited but 90% of my staff are bilingual.
