What Is Kate Walsh Doing After 'Grey's Anatomy'? Addison Montgomery Is Just A (Happy) Memory These Days

ABC

When Addison Montgomery first appeared on Grey's Anatomy at the end of Season 1 she was the doctor everyone loved to hate. She unapologetically strutted into Seattle Grace fresh from New York, wearing a fur coat in search of her estranged husband, Derek Shepherd aka McDreamy who was too making googly eyes at Meredith Grey to remember he was still married. But fans couldn't blame Derek too much — Addison had cheated on him with his best friend. Actor Kate Walsh played the villainous character with ease and while she caught plenty of flack at the beginning, viewers eventually grew to love the neonatal surgeon and her pink scrubs. This is why it was so sad when Addison departed the show after Season 3 for her own L.A.-based spinoff Private Practice. But, what Kate Walsh is doing after leaving Grey's Anatomy will still make fans happy.

Walsh still made a habit of dropping by Grey's once per season. But the last time Addison was seen in Grey Sloan Memorial was in the Season 8 parallel universe episode "If/Then," where her character appeared in Derek's alternate reality. So just what has the actor been up to since then? It turns out, plenty!

In addition to Private Practice, Walsh went on to star in films like The Perks of Being A Wallflower and Scary Movie 5. She also starred as the titular character in NBC's Bad Judge, with plenty of smaller roles weaved between, according to IMDB. But in 2017 Walsh had another major breakthrough role.

Starring as Hannah Baker's mother Olivia in Netflix's critically-acclaimed original drama series 13 Reasons Why, Walsh tapped into both the grief of losing a daughter and the desire to understand why she chose to take her own life. She also starred in 2017's summer comedy Girls Trip, the first film written, produced, directed, and starring an all-black cast to make $100 million at the box office, as the zany agent Liz Davelli. Walsh also played an eccentric doctor at an animal shelter in the Netflix comedy film #RealityHigh.

While it seems as though she hasn't stopped working since she left Grey's, the actor recently revealed that she took a break from acting in 2015 after having a brain tumor removed. In an interview with Cosmopolitan, Walsh recalled the moment she found out in January 2015, weeks after wrapping up production of Bad Judge.

Eventually her pilates instructor noticed that her right side was dipping. Walsh found herself unintentionally drifting off into the right-hand lane while driving and struggling to finish sentences. A trip to the doctor in June of that year revealed a brain tumor — a meningioma the size of a lemon, which, upon surgery, was found to be benign.

"As much as it was scary, I was sort of in robot mode once I found out. I was relieved that I could get in with a great doctor and one of the most amazing surgeons in the world, and have them take care of it," she told Cosmo. "I love to work hard and do 800 things at once, and this was a really amazing lesson in just submitting to the process of healing."

No word yet on if Walsh will make an appearance in the 300th episode of Grey's Anatomy airing on Thursday, Nov. 9, but here's to hoping fans get to see Addison Montgomery walking down the hospital hallways again some day.
