In recent years, a number of exhibitors have informed ADHA of conference list solicitations (often fraudulent) from groups with no affiliation to ADHA. We encourage you to disregard any offers for participant lists and avoid providing information to anyone outside of ADHA. MCI is the designated housing company for ADHA20.
