Lucy Sumner, MBA, FACMPE

Vice President, Revenue Cycle, ARC

Ms. Sumner began her career at ARC in 1991 as a Business Office Manager. She served as the Clinic Manager for five ARC clinics over the years, including supervising After Hours Clinics, and as the Director of the Central Billing Office. From 2012-2014, Ms. Sumner served as Vice President, Billing & Collections and in 2014 was named Administrator of ARC Hospitalist Services, then served as Vice-President of ARC Population Health before assuming her current leadership position.

At the heart of ARC is a commitment to putting the needs of our patients first. Improving the patient experience across the entire care continuum and each touch point is my personal passion, and I am excited about the impact that future transformations in healthcare delivery systems will have. ARC’s continued success takes an ongoing proactive approach from us all. I am honored to work with such talented physicians and staff.
