Well, if you want to take strictly Arnis, Grandmaster Fred Lazo teaches at the FCS International headquarters in Tampa on Friday nights. If you want to study FMA in general Tuhon Ray Dionaldo teaches there on Monday/Wednesdays. If you need a different schedule outside of that, there are a number of certified instructors under Tuhon Ray living in the Tampa Bay area including myself. For more information you can visit www.fcskali.com or visit my myspace page located in my signature.
PS Grandmaster Fred Lazo is a legend in the FMA community. Google him. Besides that he is also a swordssmith, scholar and a gentleman. I wish you the best of luck on your new journey.
