From what I have seen and heard, fencing isn’t a really big thing at NMH. It was recently revived and they’re only now beginning to compete. So, it’s not one of those established interscholastic teams that people normally get recruited for.
I will say that it seems to be on the rise. The school seems interested in maybe expanding the program, so while it most likely will not be a deciding factor, your experience might help. Question though, are you really interested in pursuing fencing? If so I have to ask myself why you would apply to a school with such a weaker fencing program.
