We live in Central Jersey, in the Princeton area, and divide our time between FASJ in Cherry Hill and Mr. Ma Fencing in Hillsborough (you can learn about both clubs at
www.fasj.com). There are a ton of really terrific clubs here, and you can find links to most of them at njfencing.org. I'd like to think that most of our fencers (mainly foil and saber) are happy with our club; Medeo in Bridgewater and BCAF in Lambertville are other good clubs to try. I think one good way to choose would be to visit each club to get a feel for the personalities and the program. Each club also has a winter camp program (the week after Christmas). If you're interested in observing the program at Hillsborough, stop by on MWF from 7-9pm; for Cherry Hill, visit Tues or Thurs from 5-7pm or Sat from 1-4pm.
Hope this helps, and welcome to Central Jersey!
