Greg OttoPlayed by Diedrich Bader
Greg Otto is well-educated a professor of history; he's warm, and loving, and has a sharp dry wit. Greg is married to Katie and the father of teenagers Taylor and Oliver and 7-year-old Anna-Kat. Greg adores Katie and has absolutely no problem with the fact that she's a larger sized woman. In fact it really gets him going! He is always reasonable, the voice of logic, and often the only barrier between the rest of the world and Katie's somewhat ill-conceived plans. Greg's a good dad but he takes his parenting cues from his wife.
