Zeroing in on one portion of the health care market and doing it well has paid off for Cindy Heit-Welch. As president and majority owner of Centerville-based Gem City Home Care, she has led the company to a jump in revenue, a pending relocation to a larger office and a healthy optimism about the future.

Heit-Welch opened the company seven years ago with a plan. Having two health care businesses behind her, one in Dallas in the 1990s and another in Dayton later that decade, Heit-Welch had the experience and a strategy to grow her third firm to high revenues.

She decided to focus Gem City on only intermittent home care, which is home care administered through home visits by skilled workers. Heit-Welch avoided the risk of delving into other health care businesses such as hospice care and that has paid off.

“We knew going into this business that we were going to be doing one thing only and do it well, and it’s wonderful that our one focus has worked,” she said.
