The founder and chief executive officer of Carmel-based Mainstreet has resigned as chairman of the board of directors for subsidiary Mainstreet Health Investments Inc. Zeke Turner says he is stepping down to focus on Mainstreet's continued growth.

Mainstreet Health Investments was formed in 2016 through a reverse takeover transaction between another Mainstreet subsidiary, Mainstreet Investment Co. LLC and Canada-based Kingsway Arms Retirement Residences Inc. The deal gave Mainstreet a portfolio of 10 senior care properties near Chicago.

Another board member, Rob Dickson has also resigned from the board. The company says Chuck Herman, former president of seniors housing and post acute at Ohio-based Welltower Inc., has been appointed to the board while existing board member Richard Turner has been appointed chairman.

Mainstreet Health Investments did not state a reason for Dickson's departure from the board.
