Carissa Ortiz

At Tiny Mammoth, I managed onboarding for new clients, coordinated kickoffs and system setup, and served as their primary contact for communication and issue resolution.

I coordinated with internal teams on campaigns and workflow improvements, tracked account performance, and shared client updates. I also maintained client data and assisted with email and SMS campaign scheduling.

At R1 RCM, I managed medical billing and insurance claims using EMR/EHR systems, submitted claims, and followed up on denials. I worked with providers on accurate documentation while maintaining HIPAA compliance.

My healthcare experience also includes maintaining patient records and supporting scheduling, billing, patient care, and surgical preparation. I’m seeking a flexible, part-time remote role in virtual assistance or administrative support.
