At Mass General Brigham, I manage complex transplant claims and denials, working through payer requirements and contractual guidelines. I also serve as a Tier II escalation resource for high-dollar claim issues and investigate billing discrepancies.

Previously, I managed insurance billing and accounts receivable for dental practices at Perfect Smiles Dentistry and Gianino, DDS. At Partners HealthCare, Inc., I resolved healthcare billing inquiries and was selected to train and mentor new employees.
