Department of Anesthesiology APP of the Quarter: January 2024
Sean Miller has been working in medicine for the past 18 years. He began working as a Paramedic for both rural and suburban EMS districts. He spent two years of his EMS career with a focus on critical care pediatric transport with St. Louis Children’s Hospital. He later entered St. Louis University’s Physician Assistant Program where he earned his Master of Medical Science (MMS) degree in 2014.
He first gained experience as a PA in primary care outpatient medicine but later transitioned to the ER. He completed an ER fellowship and remained with the ER for additional training. After completing his ER training, he entered Urgent Care medicine where he has spent the bulk of his career. Most recently, Sean’s drive for professional growth allowed him to begin work at Washington University School of Medicine in St. Louis in the Cardiothoracic ICU. When not working at WashU he returns to SLU as an Adjunct Faculty member providing lectures in EKG analysis while co-managing the orthopedic, cardiac, and GU/Renal modules. In 2023, he began operating Rapid Med Ed, LLC, which is a St. Louis-based training organization for all AHA courses and much more. He and his wife have 3 growing boys ages 10, 8, and 6. They all enjoy playing UNO and traveling to the beach for much-needed relaxation. Fun fact, he has enjoyed Martial Arts for over 25 years and currently holds a 4th degree black belt!

Alex Mohrmann, CRNA
CRNA Clinical Chief at BJH
Department of Anesthesiology Featured Member: May 2024
Alex has been a CRNA in the Department of Anesthesiology since 2018. Currently, he is the Clinical Chief CRNA for BJH, and can be found working in any POD across South Campus, Parkview Tower, or the CAM. Born and raised in St. Louis, Alex initially graduated from Mizzou with a bachelor’s degree in Nuclear Medicine, but quickly realized that the nursing profession offered far more opportunities. Subsequently, not long after leaving Mizzou, Alex moved to Chicago where he obtained an accelerated BSN degree from Loyola University.
Fun fact; while in Chicago, Alex spent one football season working as a beer vendor during Bears games at Soldier Field, walking the aisles and perfecting his signature beer call.
After the birth of his first child, as most St. Louisans do, Alex returned home to St. Louis, where he worked as an RN in the CVICU at SLU Hospital for the next three years. After graduating from the Goldfarb Nurse Anesthesia program, Alex joined the WUDA team, where he’s remained ever since.
Alex lives in Creve Coeur with his wife and three children ages 6, 8, and 11. A lifelong St. Louis sports fan, Alex tries to take his kids to as many Cardinals and Blues games as he can, cementing their fandom from an early age. Two of his biggest accomplishments include once winning a pizza-eating contest and hitting a homer at the old Bush Stadium, although not on the same day.
