William "Will" Brown, MD. Will is Brown's nephew, he is the nephew of Mr. Brown, and the cousin of Cora. He is married to Sasha, and is the foster father (in Seasons 1-2), and eventually, the adoptive father (in Seasons 3-5) of Brianna and Joaquin. He is a very well-accomplished and intellectual medical doctor, specifically a general surgeon and an emergency room trauma surgeon. He and Sasha both work at the local Grady Hospital in Atlanta; Sasha works as the chief nurse at the hospital. He is a nice man, overall, who loves his wife and family, and has close relationships with the rest of the characters, despite the fact that he may have conflicts with them sometimes. However, he still is always willing to forgive and compromise and resolve problems with them when they arise. He is also very strict towards Brianna and Joaquin and gradually learns to soften up his discipline on them as he goes through Seasons 4-5, when he realizes that he can trust them to be more mature and responsible.
