Roland Buck III played Dr. Noah Sexton on Chicago Med for NBC. Noah Sexton, first introduced in season 1, is the younger brother of nurse April Sexton. He started as a medical student and advanced to a resident in emergency medicine, then to general surgery. He faced numerous hurdles, such as committing medical blunders and crossing ethical boundaries.

In season 1, Noah appeared as a medical student at Gaffney Chicago Medical Center. He had to endure the high-pressure environment of the Chicago Medical Center.

Because of his arrogance, he found himself in direct conflict with his ED nurse sister, April Sexton. While being a student, he earned some respect, which motivated him to try and prove himself as a decent doctor.

Noah took on the role of an emergency medicine resident in seasons 2 and 3. He battled critical challenges, including a patient’s misdiagnosis, an ethical dilemma, and understanding the value of responsibility and cooperation.

He also had April on his side, but she ended up being challenging due to Noah’s professional hardships. His mistake almost caused a patient’s death in season 3, episode 11, Folie a Deux.

His medical career progressed further in seasons 4 and 5, where Noah worked independently, but his lack of experience resulted in oversights. He got involved in complex and sensitive situations, such as caring for trauma patients, handling gang violence, and facing ethical dilemmas.

Noah's story took a significant turn in season 6 after he decided to depart from the hospital. In episode 5, When Your Heart Rules Your Head, Noah clandestinely gave Dr. James Coleman, a suicide-attempting patient, the means required to end his life.

This kind act broke medical ethics and resulted in Dr. Ethan Choi firing him from the residency program while still allowing him to keep his license.

Noah showed up in season 8, episode 9, This Could Be the Start of Something New, for a short cameo during April's wedding with Dr. Ethan Choi.
