A real person to help make Medicare easier to understand
I'm Alan Blackwell, a California-licensed insurance agent based in Arcadia.
I'll help you understand how Medicare works, explain the differences between your coverage options, and identify questions to ask about your doctors, prescriptions, and costs.
We can talk by phone or Zoom, so you can get help from home. You can ask questions, take your time, and decide what you want to do next.
You don't have to make a decision during our conversation.
Your Medicare choices depend on where you get your care.
A plan may include your regular doctor but not the hospital or specialist you want to use. That's why it's important to check the doctors, hospitals, and medical groups you rely on before choosing coverage.
Choose your city to learn about local healthcare providers and how to check whether a plan covers the care you need.
