Time for an appointment at Seattle Grace. For this list, we’re looking at the most memorable from "Grey's Anatomy's" expansive line-up of characters.

Our list includes Izzie Stevens, Callie Torres, Mark Sloan, Alex Karev, Miranda Bailey and more! Join MsMojo as we count down our picks for the Top 10 Best Grey’s Anatomy Characters.
