Pat O'Sullivan

Regional Director

Pat O’Sullivan and partner, Nobby Lewandowski, C.P.A., founded The O’Sullivan Group (OSCG) and Premier Billing Network, L.L.C. (PBN) with the vision to become the most customer service-oriented consulting and billing service company in Ohio.

Pat’s experience as a consultant with other medical billing companies allowed her to develop strategies and services that competitors do not have.  Under her leadership PBN and OSCG thrived, providing medical billing, claim processing, coding receivables management, credentialing, and practice management services for over 20 years.

In 2018, Pat began an extensive search for merger opportunities to help ensure a stable future and ongoing success for PBN and OSCG employees, partners, and customers.  In the summer of 2020, Pat found the perfect partner in UnisLink.

With the merger complete in Fall 2020, Pat leads a team of specialists and combined talents with expanded capabilities and resources, representing the premier healthcare consulting and billing company in the region.

Pat has over 30 years of medical practice management experience in a multitude of specialties.  She looks forward to bringing this experience to your practice.
