Tennessee Otolaryngology Society was founded in a joint venture by Dr. Daniel Sacks, with Otolaryngology Associates of Tennessee and Dr. John Seibert with Vanderbilt Otolarynology/Head and Neck Surgery. The common goal that both Sacks and Seibert have is to create a greater collaborative group for ENTs in the state of Tennessee.
