An Update on the CLEO Exhibition

Thank you for your patience as the CLEO co-sponsors, in close coordination with the CLEO Chairs and volunteer leadership, focus on plans for CLEO 2020.

The CLEO technical program will move forward but in a different format. We are not planning to host an in-person exhibition. This likely comes as a disappointment for all, but the health and well-being of all of our participants is paramount.

Please take the steps you need to minimize your ancillary expenses, such as hotel reservations, labor and production, airfare, etc. We will be in touch shortly with additional details on exhibitor refunds and credit options.

Although you won’t have the opportunity to meet with attendees in person, we are exploring opportunities for you to still engage with the scientific and industry professionals that comprise the CLEO audience. More details on how to extend your brand recognition and connection with this community will be available shortly.

Thank you for your continued support of CLEO. We look forward to seeing you in-person in 2021. We wish you the best as you navigate these challenging times, and the best of health to you and your teams.
