Kelsey Rotz had spent the better part of an hour with a small group at the library Saturday going over basics of Medicare shopping and registration.

he covered details of hospital visits, doctors’ offices and Advantage Plans and was about to address Part D, the part of Medicare related to drugs and pharmacies.

One visitor to the session wondered how Rotz, a recent Freed-Hardeman University graduate, had already developed such an understanding of the wide-ranging Medicare program.
