In 1990 Dan O’Connell purchased two small collection agencies then known as Bonded Collections of Marshfield and Rapids Adjustment Company.  In June of 1992, Bonded Collections purchased 50% of the stock of Wausau Creditors Service, Inc., and the balance of that stock was purchased in June of 1998.  In 1999 Bonded Collections of Marshfield, Rapids Adjustment Company, and  Wausau Creditors Service were merged into Alliance Collection Agencies, Inc.

As Alliance grew, Dan had identified local healthcare providers were in need of additional revenue cycle services beyond traditional 3rd party bad-debt collections and as a result formed HealthCare Business Services (HBS) in 2004.  

In 2015 the RevCycle brand was launched creating a comprehensive and integrated suite of revenue cycle products and services.
