What I'm looking for

I seek a role where I can apply fraud-investigation and clinical operations expertise, work within a compliance-driven culture, mentor junior staff, and contribute to process improvements and accurate member/patient outcomes.

I am an experienced Fraud & Digital Investigator and trained clinical laboratory technician with a track record of resolving complex account discrepancies, handling sensitive transactions, and delivering excellent member and patient service.

At Navy Federal Credit Union I analyze and research account issues, assist members with loan and account processes, mentor Level I team members, and ensure compliance with federal regulations while performing platform-banking functions and custodial duties as needed.

My laboratory background includes phlebotomy, specimen processing, billing and claims preparation, training new hires, and managing patient records. I bring strong attention to detail, time management, and a commitment to accuracy in regulated environments.
