@crystalguillen
Experienced Customer Service Representative skilled in healthcare accounts, Medicare support, and admin accuracy.
What I'm looking for
I’m an experienced associate who brings customer-first communication, problem solving, and strong documentation habits to every role. I’m at my best helping people with complex information while staying organized, punctual, and accountable to company goals.
In healthcare customer service, I review patient account information across multiple systems, resolve inquiries and account balances, update insurance and demographics, and document actions carefully while adhering to HIPPA and company policy. I also support Medicare beneficiaries with plan guidance, enrollment issues, Part D drug assessments, and clear explanations of regulations in a friendly, empathetic way.
I’ve also built a deep administrative foundation through secretarial and multitasking duties—scheduling meetings, preparing memorandums, tracking shipping and receiving, maintaining logs and data sheets, and generating reports. Across my work in customer service, nursing support, and accounting coordination, I consistently maintain compliance, protect confidentiality, and keep accurate records that support smooth operations.
