Gleason most recently recurred on eight episodes of Mom as an Alcoholics Anonymous member. As Kimberly Roots notes, "though you may not have known Gleason’s name, it’s likely that her face is familiar: Her acting resume contains more than 100 television credits, usually for one-off-but-memorable roles on popular broadcast series in the past 40 years. She was Madame Oeuf, Saved By the Bell‘s French teacher. She was Lucille, the stern yet kindly dressing-room attendant who hugged a grieving Miranda in Sex and the City. She was Mrs. Butters, the no-nonsense elementary school teacher who dealt with Lynette and Susan’s kids in Desperate Housewives. She was Sally, the homeless woman who may or may not have known the president on NBC on Will & Grace."
