List of Coronation Street Characters (2005) - Zack

Zack is a psychiatrist who treats Shelley Unwin when her anxiety overtakes so much of her life that she is rarely able to leave her own room. Zack helps Shelley slowly go back to the outside world, but Shelley's boyfriend Charlie Stubbs resents Zack's efforts to help, and eventually convinces Shelley to stop seeing him. Shelley progresses far enough that she manages to dump Charlie moments before she is to become his wife. After getting away from Charlie, she calls Zack to tell him the news. He says that he is proud of her, and both agree to continue therapy until she is fully recovered.
