Our Team

Harry Cohn

Harry Cohn

President and CEO

As Harry approaches his 30th year in the commercial real estate business, there are many wonderful stories to tell.

From his modest beginnings of starting his first real estate company in Chicago at the age of 28 to now running a successful commercial real estate brokerage business at Cohn Commercial Properties new Headquarters in Sylvan lake, Michigan (and many steps in between), it has been quite the ride.  During Harry’s career, he has had the distinct pleasure in working for and with several developers and retailers that are too many to name.

Harry has been blessed to have participated in several charitable causes, including his work with the Friendship Circle and Integrative Neighborhoods, an intentional community developed by Harry’s wife that provides an independent living alternative for the special needs community.

When not at the office, Harry enjoys traveling, running, biking and spending as much as time on the lake during the Michigan Summers.
