In The Middle episode “The Convention,” Frankie Heck (Patricia Heaton) works as a hygienist for goofy dentist Dr. Ted Goodwin (Jack McBrayer, Kenneth on 30 Rock). Now that the dental office is a part of the dental franchise Smile Superstars International, Frankie attends the company’s annual conference and there meets corporate leader/motivational speaker, Dr. Sommer Samuelson.
Dr. Samuelson is portrayed by Cheryl Hines. She’s best known for her roles on Curb Your Enthusiasm (Cheryl David), Suburgatory (Dallas Royce), and in the 2006 family film RV with the late great Robin Williams (she plays his wife, Jamie Munro). Fun fact about Hines: Last year she married Robert Kennedy, Jr. The Middle airs Wednesdays at 8pm on ABC.
