Altrincham have signed midfielders Gareth Whalley and Cavell Coo, and striker Matthew Berkeley.
Whalley is the most experienced of Altrincham's three signings
The trio were released from their previous clubs at the end of last season, while Coo and Berkeley had both been on trial with Altrincham.
Whalley, 33, left Swindon earlier this summer but has made 361 league appearances for five clubs.
Coo, 19, was freed by Crewe, while Berkeley, 20 on Friday, was released by Scottish Premier League side Gretna.
