KINGSPORT — It’s a turning point for the Board of Mayor and Aldermen. Three members are coming off the board; three new members will soon be joining the ranks. Tuesday night’s BMA meeting was the last official meeting for Aldermen Tom Parham, Darrell Duncan and Tom Segelhorst. Parham and Duncan lost their bid for re-election in the May 16 city election, while Segelhorst chose not to run. The newcomers to the BMA — Jennifer Adler, Joe Begley and Betsy Cooper — will be sworn into office next month.
