Chicago Med Season 11 cast and character guide
S. Epatha Merkerson as Sharon Goodwin
Sharon Goodwin is still the Chief of Patient and Medical Services. In Chicago Med Season 11, Goodwin has to cope with challenging administrative decisions, balancing the concerns of employees and patient needs, and doing his job in harsh circumstances.
The presence of Merkowitz in television is long and has earned her credibility and sympathy through her Emmy-winning appearance in Lackawanna Blues and 17 seasons on Law and Order.
Oliver Platt in the role of Dr. Daniel Charles
Dr. Daniel Charles continues to be Chief of Psychiatry and offers emotional support and counsel to the patients and even the staff members. Chicago Med Season 11 is also characterized by professional challenges since Charles has to handle younger employees and address the mental health needs of a high-stress hospital environment.
His eclectic film and television career, in such films as Frost/Nixon, The West Wing, and The Bear, is in service to his subtle performance as a caring and yet realistic psychiatrist.
Steven Weber in the role of Dr. Dean Archer
Dr. Dean Archer still has to contend with accuracy in the ER when there is office politics. Chicago Med Season 11 deals with his past and the fact that he is suddenly an unexpected father of an unexpected pregnancy with Dr. Hannah Asher, and it is tense on a personal and professional level.
Weber, best known for Wings, NCIS: New Orleans, and 13 Reasons Why, adds a combination of humor, incisiveness, and emotion to Archer.
Jessy Schram plays the role of Dr. Hannah Asher.
In Chicago Med Season 11, Dr. Hannah Asher is the character who unexpectedly becomes pregnant with the father being Dr. Dean Archer. It is a narration of the way personal life and professional responsibilities become interwined and cause ethical and emotional distress.
Past credits that Schram has done in Veronica Mars, Falling Skies, and Once Upon a Time have prepared her to perform vulnerability and strength in her character.
Dr. Mitch Ripley is portrayed by Luke Mitchell
Dr. Mitch Ripley is one of the most important emergency physicians, who makes life-and-death decisions faster to manage office politics. In Chicago Med season 11, it can be seen that Ripley has developed the ability to handle interpersonal matters, such as the one where Asher becomes pregnant without sacrificing his professionalism.
The fact that Mitchell has previously worked on Neighbours, Agents of S.H.I.E.L.D., and Blindspot makes his performance sound more positive as a self-confident and multi-dimensional doctor of the ER.
Sarah Ramos as Dr. Caitlin Lenox
Dr. Caitlin Lenox remains the Chief of the Emergency Department, but has a major personal problem; she has been diagnosed with prion disease. The theme of Chicago Med season 11 is the effects of the illness of Lenox on her working life, which depicts how medical staff are vulnerable to personal health emergencies and are willing to respond to their needs first.
Ramos, the star of Parenthood, The Catch, and The Affair portrays Lenox with all dignity, strength, and empathy.
Darren Barnet plays Dr. John Frost

Conor Perkins plays the role of Dr. Zach Hudgins, and Henderson Wade plays the role of Dr. Loren Johnson.
Dr. Zach Hudgins and Dr. Loren Johnson, who work with the emergency services and hospital administration, are also recurring cast members who provide continuity between the previous seasons with Chicago Med season 11. The two characters belong to both patient cases and team dynamics, and thus loyal viewers are introduced to the same faces tackling new issues.
