Ten years ago Americans got their first taste of McDreamy when Grey’s Anatomy premiered on March 27, 2005.

The Shonda Rhimes-created drama, currently in its 11th season, was first advertised as a show that features the “intensity of medical training mixed with the funny, sexy, painful lives of interns who are about to discover that neither medicine nor relationships can be defined in black and white. Real life only comes in shades of grey.”

A decade later, many of Grey’s “interns” have grown into Hollywood stars, and the show has had more drama – on and off-screen – than most hospitals see in a lifetime.

But if the #TBT culture of the Internet has taught us anything, it’s that it is important (and often hilarious) to return to your roots.

So, to celebrate Grey’s Anatomy‘s 10th anniversary, we traveled back in time to when the show’s Season 1 cast was getting their first set of head shots.

Get ready for a lot of serious doctor face.

Ellen Pompeo as Dr. Meredith Grey

Here’s Pompeo sporting the first of many hairstyles to inspire “How Do I Get Meredith Grey Hair?” boards on Pinterest accounts everywhere.

Patrick Dempsey as Dr. Derek Shepherd

We like to call this one, “McDreamy Mid-Daydream.”

Justin Chambers as Dr. Alex Karev

Doctors: the only professionals who can make clipboards look sensual.

T.R. Knight as Dr. George O’Malley

Nothing says young rookie intern like a shaggy, juvenile bowl cut.

Chandra Wilson as Dr. Miranda Bailey

Doctors: Also the only professionals who can make clipboards look intimidating.

Katherine Heigl as Dr. Izzie Stevens

Resident getting ready for her first shift, or girl heading to a high school sleepover? You decide.

Isaiah Washington as Dr. Preston Burke

Even fictional doctors know the importance of emergency room hygiene.

Sandra Oh as Dr. Cristina Yang

Beeper and badge fastened to her scrubs, Yang is ready to save lives and make calls from a payphone.
