With health insurance one of an employer's top costs — if not the top cost — businesses are constantly on the lookout for ways to save money. For some businesses, the answer may seem counterintuitive — expanding their medical offerings available through onsite employee clinics. During a recent three-month span, the Kimberly Area School District estimates it saved more than $30,000 — or 53 percent — in health care costs with employees using the district's clinic instead of them seeing their regular health providers, says Dawn Ludwig, director of human resources for KASD.
