Looks like its foundation is Inosanto based jkd/Kali. Believe I picked out Eric Paulson in a pic or two. FMA teaching is not under an organization that regulates curriculum. Hence, style, philosophy and quality of instruction is all over the map. You’ll just have to check it out and see if it’s right for you. For older folks, FMA is a great way to increase fluidity, suppleness and balance. I will be 68 this year and owe much to the FMA’s and the great instructors I’ve had.
