Shepherd has signed a one-year deal with the National League North outfit and joins for an undisclosed fee.
The young left-back joined Whitby in 2020 from Hartlepool United and grew into a regular starter in the Seasiders’ defence, making 37 appearances last season.
Shepherd now links back up with Mariners Head Coach Elliott Dickman, who worked with the left-back in Sunderland’s academy.
