Our History

Both Larry Jantz and Robert Corne came to Colorado in 1979 to work for Benson Wells & Company (BWC). BWC was a regional CPA firm providing a full range of accounting and tax services to clients located in a number of states. Eventually, BWC narrowed its focus to provide tax planning, compliance and consulting services to individuals and closely held businesses. The major industry groups serviced were real estate, construction, the medical profession and the manufacturing industry.

Larry and Rob left BWC in January of 2003 and formed Corne Jantz & Associates, P. C. John joined them at the firm in 2006. We continue to specialize in tax planning and consulting to individuals and closely held businesses across the U. S. Our staff is experienced with a number of accounting software programs but specializes in Quickbooks applications. Our firm continues to provide the high level of "commitment to excellence" upon which BWC was founded.
