Kelsey joined the club from Herts Vipers at the start of the 22/23 season following the folding of the side. Having played previously for Watford and Harvesters, the young winger arrived with her own vocal fan club and an air of excitement whenever the ball got to her feet. That season saw Millen rack up ten goal involvements in twenty-eight appearances – the only ever present in the team that year. This season has seen Kelsey equal the goal involvements by December and although she is not quite an ever present this season, she is still a vital part of the fabric of the side, backed up by the statistic that she can reach 50 appearances quicker than any other player for Stevenage in recent memory at her current appearance rate.
