The Superstition Springs Leads group is the best leads group in the Mesa Chamber of Commerce, in my opinion. Of course I'm a little bias since I'm in the group :-)
You'll be given "30 seconds" to introduce yourself and your business to the group. There is also plenty of time for open networking after the formal meeting ends.
Members of this meetup group are welcome to come visit the leads group for free as my guest up to 3 times. If you find that you like the group or that it fits with the growth strategy for your business then you're invited to join the group as long as your industry is not already represented.
Mention that you heard about this event through "Rex's Meetup".
