He is a partner with the West Jefferson Emergency Physician's Group and has worked there since completing an emergency medicine residency at the LSU/Charity residency in New Orleans in 1990. This group is a single hospital democratic emergency medicine group which has staffed West Jefferson Medical Center's Emergency Department for decades. Dr. Mayer became interested in AAEM in the early years of the organization after working part time for a contact management group and being able to first hand compare it to a democratic group. He served in all levels of office of the Louisiana State Chapter of AAEM and served on national committees before becoming a member at large of the national board. He is committed to emergency medicine practiced in a fair and open and democratic manner.
