Hi Edward. I agree with Kevin in that I think that now that you are certified, coupled with your previous experience, you should be marketable to most of the gyms in your area. I also agree with Kevin that remaining “independent” is probably the best way to go, but this is always a personal decision that you will have to weigh based on your own set of circumstances. Only you will truly know what will work best for you. There are definitely pluses and minuses in both situations (i.e. working as an employee for the gym, or as an independent contractor); consider and weigh them carefully before making your decision.
Congratulations on your new certification! I too hold a certification through AFAA.
I hope that this helps.
