Atlanta Gay and Lesbian Chamber of Commerce

The AGLCC is a quality organization. It’s also been a huge resource for me in my current gym — the LA Fitness at Ansley Mall — for finding businesses who make strong prospects for advertising there.
Their website is pretty thorough (you won’t find a business listed in every category but they have set it up to cover pretty much every type of business you can think of so it’ll be easy to add new Chamber members to the right category when they join). There’s a lot of information about current events, gatherings, and a significant amount of «deals» to be found (ie, who offers a discount for what service/​product). There is a contact person listed for nearly every business and many have thorough profiles describing who and what they are.
Many of the members have been involved for years (each listing has a notation for how long the business has been a member). You’ll find everything from lawyers to contractors, and more. If you’re a business owner or employee who would find this resource helpful for finding clients, conducting business or because you want to support this particular segment of Atlanta’s business community, check out the AGLCC.
