Hi Debbie. This is a question that I’ve faced when I served as the Director of Wellness and Fitness at a local College, and in a position as Fitness Director at a large corporate fitness facility. I think that all of what you describe your are currently doing is great. A Wellness Day, a Health Fair, an Assessment Day, a regularly published wellness newsletter, email blasts etc are all potentially useful in increasing membership. However, unless and until you get the buy-in of the employers, the employees will not feel supported in your efforts to get them in the fitness center. Targeting some of your “education” to the employer and its administrators is a KEY! I offered a 3-session free package to a key individual or two in the various companies, and some took advantage of the offer. Those who did, really got an eye-opener, and several went on to become “regulars.” With their now increased personal interest in the fitness center and exercise, they became role models as well as supporters of their employees doing the same.
I hope this helps.
