I really enjoy this group because it is smaller and more intimant then some of the others I have attended, there are workshops and peer coaching groups as well as get aways, and general networking events for men as well as women. Memberships range from $27 to $197 per month.
National Association of Women in Business
This is a smaller group, 20 or less and meets for dinner once a month in a woman's home. They started in Texas and are looking for people who want to franchise all over the US
This is a little like linked in with an online profile but with added coaching as well as in person networking events one time fee of $290 plus $16 per month.
