Our Story

Reviving The Classic Gentleman

  In 2019, Dennis Matthew was founded in Defiance, Ohio with a strong desire to transform the ordinary man into a classic gentleman. Founder, Dennis M. Postema recognized the need for a men's fashion brand that was in a league of its own, it needed to be a lifestyle dedicated to reigniting the image of a true gentleman. A gentleman is gallant, he's chivalrous, he opens doors, offers his coat, and pulls out seats for his life partner. Therefore Dennis Matthew was born with cutting-edge fashion designs to have you looking and acting the part of a true gentleman.
