Michael Gross is preparing to Suit up.

The actor, forever best remembered and beloved for his role as the Family Ties patriarch, will appear on multiple episode of Suits Season 4 as a businessman named Walter Gillis.

According to network sources, the character is the founder of a groundbreaking DVD distribution company and will need legal assistance due to various takeover bids while he attempts to keep his business solvent.

Gross (Last Man Standing, CSI and How I Met Your Mother) joins Brendan Hines (as the son of a millionaire) and DB Woodside (as an ex-SEC attorney) on Season 4 of Suits.

The Suits Season 3 finale, meanwhile, airs tomorrow night.
