Our Organization

The Corporate Event Marketing Association advances strategic event marketing and marketing communications for senior-level event marketers and industry professionals.

Our Passion

CEMA is a thriving community of corporate event marketers. We serve all senior-level event marketers in a corporate environment. The diversity of our corporate membership continues to expand, and our recent acceptance as members of the Events Industry Council (EIC) have enabled us to expand our reach even further.

Our differentiator is our non-selling, peer-to-peer environment. Conversations among participants at our events focus on best practice sharing and knowledge sharing. Relationships are first and foremost. Professionals do business with other professionals they trust. CEMA facilitates those connections and lifelong industry friendships.

CEMA members engage in person through educational and networking opportunities offered each month around the country. CEMA Study Tours are our most popular professional development opportunity, providing behind-the-scene knowledge sharing about industry events.

Members also engage online via Twitter, LinkedIn, and Facebook.
