Established in 2003, OneSource started as a joint venture between Smoker & Company, Leola and Levandowski & Associates, Reading.  Smoker & Company was established in 1985 and is a full service accounting firm offering comprehensive business services and consulting.  Levandowski & Associates was founded in 1996 to assist all types of businesses by providing "hands-on" operational accounting and business consulting.  The joint venture, originally named Smoker & Levandowski LLC, was developed out of the desire for both companies to expand their market areas and provide a stronger foundation for clients interested in growing their business.  Our services are specifically designed to help businesses achieve profit improvement and growth by creating a structure for them to address business issues through strategic and operational reviews.

In 2005, the company was renamed to OneSource Business Solutions LLC to reflect the company's expanded suite of services and growing geographic client base in the Mid-Atlantic region.
