Senior Quality Assurance Supervisor at iCore improving performance and processes across U.S. dental operations.
What I'm looking for
At iCore, I oversee quality and operational performance across a distributed team of 3 supervisors and approximately 30 agents supporting nearly 100 U.S. dental offices. I monitor KPIs, productivity, quality scores, deadlines, and workflow progress to identify risks and performance gaps.
I analyze quality and performance trends to find root causes and recurring issues, then develop QA processes, tracking systems, reports, and dashboards to support data-driven decisions. I also serve as a senior escalation point for complex operational and client-related issues.
At EZ Dental Billing LLC, I supervised agents, monitored quality and productivity, and supported resolution of complex billing and workflow issues. Earlier, I managed billing operations for U.S. dental offices, including claims submission, eligibility verification, payment posting, and accounts receivable.
I hold a bachelor's degree in Hotel Business and Hospitality from SENAC Minas and a Cambridge English C1 certification. I'm interested in Operations, Quality Assurance, Process Improvement, Business Operations, and data-driven operational roles.
