There are also corporate clubs. Membership may be restricted to staff of the particular organization. This can be due to the company wanting to keep the club homogenous i.e. employees or managers only. There may be security issues as well. Security clearance may be required to attend the meeting in their secure building that they wouldn’t want to open up to the public.
It could also be a little more challenging in attending a corporate club meeting. You would want to make your arrangements in advance with the club executive rather than just showing up.
Your membership will provide you ample opportunities to attend other clubs. Over and above the club there are also Area, Division & District events that can be of value.
