In mid-March, recently appointed ProBuild CEO Robert Marchbank said the company would spend three months “reviewing what resources will be needed going forward to support the business.” By mid-June, the nation’s biggest full-service lumberyard had begun to decide what to do: cut 127 corporate positions at its Denver headquarters.

Cuts were made June 19 across all headquarters departments; a company spokesperson declined to say which departments were affected most. Lonnie Bernardoni, senior vice president for manufacturing, was the highest-ranking officer to go.

Last July, former CEO Bill Myrick stepped down less than two weeks after the company dissolved its regional offices and restructured itself into three groups focusing on metropolitan, smaller local, and specialty markets. Nine months later, it abandoned that setup.

ProBuild ranks No. 2 on the latest ProSales 100 survey with $3.5 billion in total sales in 2011, 6% less than in 2010. It operates more than 420 stores and counts more than 9,000 employees.
