At Edgewood Summit retirement community in Charleston, W.Va., 93-year-old Mary Mullens is waxing eloquent about her geriatrician, Dr. Todd Goldberg.

"He's sure got a lot to do," she says, "and does it so well."

West Virginia has the third oldest population in the nation, right behind Maine and Florida. But Goldberg is one of only 36 geriatricians in the state.

"With the growing elderly population across America and West Virginia, obviously we need healthcare providers," says Goldberg.
