In 1947, the Wisconsin Society of Anesthesiologists (WSA) was chartered by the American Society of Anesthesiologists (ASA) as its fourteenth (14th) Component State Society.

From an initial handful of members, currently WSA has 540+ Active members, plus a dozen Scientist & 150+ Resident members from the two training centers at Medical College of Wisconsin (MCW) and UW-Madison.

Created to provide in-state CME for anesthesiologists, today the WSA also serves patients, the general public and their elected representatives as the resource on standards of ethical anesthesia care.
