Dan Gilbert

I’m not able to find credible evidence that there is a well-known American coach named Dan Gilbert. The name Dan Gilbert more commonly refers to:

• Dan Gilbert (businessman), born January 17, 1962, American entrepreneur, majority owner of the Cleveland Cavaliers, founder of Rocket Mortgage / Rock Ventures, etc.

• Daniel Gilbert (psychologist), a scholar and author.

If you meant one of those or a different “Dan Gilbert (coach)”—for example, a sports coach in a niche field or region—please clarify which sport, era, or location you meant. I can then prepare a full biography for that person.
