Business diagnoses, treats labor niche

When I introduced you to Mary Christensen and her brother, Damian Martin, three years ago, they were operating their inventive job-placement business out of her basement and generating a modest $320,000 of annual revenue.

The business, which recruits experienced, semiretired health care executives for short-term projects or interim management positions at Minnesota hospitals and clinics, has come a long, profitable way since then.

Now ensconced in 1,600 square feet of modern office space in Bloomington, the business has increased its revenue since 2007, to a 2010 total of $1.1 million.
