Cassandra Johnsen-Barton

I am a detail-oriented Provider Service Representative with experience managing provider inquiries, resolving claims and reimbursement issues, and maintaining accurate provider records at Optum/Episource. I previously spent a decade as a Senior Chart Retrieval Specialist coordinating timely, HIPAA-compliant retrievals and improving EMR walkthrough manuals.

I train and onboard new hires, deliver hands-on EHR instruction (Epic, Cerner and similar platforms), and contribute to process improvements that increase accuracy and efficiency. I bring strong communication, active listening, precise data entry, and a commitment to confidentiality and compliance.
