Mike Grisdale

News / Sports / Marketing

A longtime radio veteran in Northern Michigan, Mike is also very active in his community. His busy schedule includes officiating basketball, serving several roles in his church (Cheboygan Catholic Community) and volunteering.

Besides handling news and sports duties on most Black Diamond Broadcasting stations, he also is an integrated marketing consultant for the company and has been the Voice of Cheboygan Chiefs football for over 35 years! Mike also serves as the Director of Marketing and the Foundation Director for Mackinac Straits Health System.

He is the proud father of three boys, Bryan, Matt and Adam. When he and his wife Sandy have free time, they enjoy spending it with their dog (Drake), traveling, concerts and sampling local restaurants.

"I have seen plenty of changes in radio over the years," said Grisdale. "But like most businesses, one thing doesn't change.... the importance of strong relationships. I have been fortunate to develop many wonderful relationships with staff, clients and most importantly, the audience."
