What I'm looking for

I’m looking to bring my high-acuity ED/PACU leadership and telehealth navigation skills to a team that values fast triage, cross-functional collaboration, and strict compliance—where I can support patient safety and smooth care flow.

I’m a Texas-licensed Registered Nurse with over 10 years of clinical experience in high-acuity Emergency Departments (ED) and Post-Anesthesia Care Units (PACU), integrated with years of corporate experience as a Cigna Phone Advisor. I’m known for rapid clinical triage, telephonic assessment, and navigating complex healthcare insurance regulations while keeping patient safety at the center of every decision.

Across roles including ED Charge Nurse and PACU Charge Nurse, I’ve led shift operations, executed Emergency Severity Index (ESI) triage scoring to reduce door-to-provider times, and managed advanced digital health records in Epic, Cerner, and Meditech. I also bring strong coordination skills from utilization review, pre-authorization workflows, remote patient advocacy, and crisis de-escalation—plus specialized vascular access expertise as a Vascular Access Nurse.
