What I'm looking for

I’m seeking to leverage my strong organizational and problem-solving skills in future customer success, senior administrator, and related roles—bringing workflow optimization, accurate patient/billing coordination, and a high-touch experience to every team.

I’m an experienced professional with 7+ years bridging clinical patient care and office management. I optimize workflows, manage complex provider calendars, and enhance the customer/patient experience—especially in high-pressure environments.

As a Patient Coordinator Manager, I maximized daily appointments and reduced wait times by managing provider calendars and patient flow. I also increased patient volume through outreach and marketing, and streamlined billing processes while maintaining high accuracy in daily financial balancing and check deposits.

Earlier in my career, I delivered high-level support for a 24-bed Medical ICU by monitoring vital signs and ventilator settings, responding calmly during medical codes, and educating families on complex medical situations. I bring that same clarity and responsiveness to every team I support.
