She made the trip to Cheshire Academy last academic year to try her hand this year and was named in the New England Prep School All-Stars team in her first season. This autumn she was also named most valuable player in the girls football team.
'I'm really proud of all three of them,' said Kim. 'They have gone out there determined to be successful and they are doing it.'
