Clark & Daughtrey staffers Deborah Renegar and Mike Sivilli were a hit with the first-graders Nov. 15, when they spoke at Padgett Elementary School in North Lakeland as part of the Great American Teach-In. The medical pros told the 6-year-olds about their jobs and the importance of a good education. Mike is the clinic's laboratory manager. Deborah is an advanced registered nurse practitioner in the Cardiology Department.
