Here's my two cents. I used to be a Chamber Exec. for two different chambers in two different states. I certainly believe in the benefits of the Chamber. With that said, I think the benefits you receive is truly dependent on the Chamber you're joining, how active and involved is the leadership, how many ACTIVE members you have, what activites and committees are available and the types of promotion (free or small fee) available to you (make sure it has great circulation). The power of networking is incredible in a highly active chamber and the exposure you can get from the various events, committees and advertising is invaluable. Membership is usually based on the number of employees and/or type of business. You should do everything you can to promote your business - ie ...business breakfasts, participate in any business expos/fairs, ribbon cuttings, advertisements in circulars and participating on committees. From what I have experienced the members that participated are the ones that benefitted the most. Good luck with it!
