Leads Groups at the Greater Irvine Chamber: The Leads Groups are the Chamber's premier lead generation and referral networks. These popular referral groups have helped hundreds of professionals gain a competitive advantage in the Irvine and Orange County marketplace, as well as build lasting professional and personal relationships. Leads Groups are comprised of 25 - 30 individuals that meet twice a month to help each other with selling techniques, presentation skills, recruiting, strategic partnerships, referral exchange, professional relationships and more. Participation in these groups is an exclusive yet complimentary benefit of membership. The Leads Groups follow a non-competing format and are limited to one person per industry and/or profession.
