MARC MARIANI, CHIEF FINANCE OFFICER
Marc Mariani began his HSI career as Chief Financial Officer in 2011 with 15 years of experience in health care finance. After earning a BA degree in both finance and accounting, he started his career as a Financial Analyst for a multi-specialty medical group in Santa Rosa, CA before joining the St. Joseph Health System of Sonoma County in 1997 as a Contract Analyst. In his 10 years with SJHS, Marc developed skills in building pricing models which were used to evaluate the performance of managed care contracts for the five hospitals of the health system in the Northern California Region. He was promoted within the health system through positions of progressively greater management responsibility, which led him to pursue a master’s degree in healthcare administration in 2005. Marc received his MHA from the University of Southern California in 2008, shortly after accepting the position of Finance Director with the Anesthesia and Analgesia Medical Group, serving Sonoma County and Napa County. Marc’s unique and in-depth experience in dealing with all aspects of the revenue cycle process from the healthcare provider’s perspective has proven to be an invaluable resource to HSI and to HSI’s clients. In July of 2016, Marc transitioned into the Chief Operating Officer role at HSI.
