Our clients retain KeySource Thomas Thor to assess their industry (and related niches) and develop strategies to identify and attract bright, result-oriented leaders who will have impact on their firm's bottom line and operational effectiveness.

The diverse leaders we place with our clients vary widely; some of our placements will develop new markets for a client, others may sit among board members at growing firms.  We place leaders who have desks in corner offices and those who guide teams dealing with tight deadlines and massive machinery.  Some of the leaders we place put on goggles, gloves and protective gear and drive results in laboratories.  Many of our leadership candidates wear hard hats and guide huge teams on vast work sites.

Regardless of the diverse environments from which our clients and candidates come, our efforts lead us to seek intelligent, diplomatic, and influential professionals who eagerly aspire to drive business improvements. Please take a look at the leadership opportunities we are currently filling for our clients.  Perhaps your next professional development opportunity is listed here.
