Mayo Clinic Military Anesthesia Statistics

There have been many past and present staff of the Department of Anesthesiology and Perioperative Medicine that have contributed to every branch of service of the United States Armed Forces. Here, we hope to honor those who are currently serving or have served. If you are a current or past member of the department and have served at any point in the United States Armed Forces, we are asking for information regarding your service and career within the department. We hope to create a database of information to showcase the effect our department has had on our Armed Forces.

Dr. Steve Rettke ( and Alec Thicke ( are currently working together to gather this information and present it on this webpage. Dr. Rettke is a distinguished U.S. Navy carrier fighter pilot and retired Navy captain, as well as long-time leader of our Methodist Hospital clinical practices.
