Katherine LaNasa: Career, Husband, Grey’s Anatomy, and The Pitt

For an actress who spent years being introduced as Dennis Hopper’s wife, Katherine LaNasa has a better introduction these days: Charge Nurse Dana Evans in HBO Max’s The Pitt. The role earned her a Critics Choice Award for Best Supporting Actress in a Drama Series, and it has quietly rewritten the default celebrity-bio headline.

Born: December 1, 1966 (Wikipedia biography) · Known for: Charge Nurse Dana Evans in The Pitt (IMDb credits) · Recent award: Critics Choice Award for Best Supporting Actress in a Drama Series · Instagram: 502K followers @ladylanasa (Instagram bio)

Eight details, one pattern: the verified portion of LaNasa’s bio now leads with The Pitt, not with either marriage.

What is Katherine LaNasa best known for?

The short answer is now The Pitt. LaNasa plays Charge Nurse Dana Evans in the HBO Max medical drama, and the performance won her the Critics Choice Award for Best Supporting Actress in a Drama Series. The prize matters because it gives her a recent credential that outranks the old biographical default.

The older default is still visible in her résumé: she trained as a ballet dancer and worked as a choreographer before acting (IMDb credits; The List profile), and early profiles often introduced her as Dennis Hopper’s wife (Rotten Tomatoes profile). The Pitt flipped that framing.

What ethnicity is Katherine LaNasa?

• Not specified in the top biographical sources reviewed for this article (Wikipedia biography).

The honest answer is that no authoritative profile in the current record assigns her an ethnicity. Her New Orleans birth and Louisiana upbringing explain a rich cultural context, but the responsible move is not to guess.

The pattern: when the record is quiet, the most defensible answer is the quiet one.

Who is Katherine LaNasa’s husband?

Her current husband is actor Grant Show, known for Melrose Place and a long list of TV roles. LaNasa’s own Instagram bio confirms the marriage by describing her as “Mrs Grant Show” (Instagram bio), and biographical accounts place the wedding in 2004 (Wikipedia biography). Before Show, she was married to Dennis Hopper (The Daily Beast report).

Who was Katherine LaNasa’s first husband?

• Dennis Hopper, the actor and filmmaker behind Easy Rider (The Daily Beast report).

She reportedly met Hopper while touring Los Angeles with Karole Armitage’s ballet company in 1987 (The List profile). They married in 1989, when she was around 22 and he was around 53 (The Daily Beast report).

How old was Katherine LaNasa when she was married to Dennis Hopper?

• 22 — she was about 22 when she married the 53-year-old Hopper in 1989 (The Daily Beast report).

How long have Katherine LaNasa and Grant Show been married?

• Since 2004, which puts the marriage more than two decades deep (Wikipedia biography).

Did Katherine LaNasa give birth to her daughter?

• Her son Henry Lee Hopper is confirmed in biographical listings (IMDb biography).

No top source confirms a daughter. If the question comes from The Pitt, it may be a scripted storyline rather than a public family announcement.

The implication: the marriage cluster gets searched often, but the verified facts are fewer than the page views suggest.

Who did Katherine LaNasa play on Grey’s Anatomy?

She had a guest role in Grey’s Anatomy, listed in her television credits (IMDb credits). The exact character name is not stated clearly in the top biographical sources reviewed here, so the honest answer is that her Grey’s arc was a guest appearance, not a series-regular run.

The exit did not come from a reported behind‑the‑scenes conflict; guest arcs end because the storyline ends.

Why did Katherine LaNasa leave Grey’s Anatomy?

• The guest arc ended with the storyline; no reported conflict is documented in available profiles (IMDb credits).

For fans of the show, the practical distinction matters: a short medical‑drama arc is not a scandal, and it did not derail the career that followed.

The pattern: the Grey’s question is really a question about how guest television works.

What else has Katherine LaNasa been in?

Her résumé is long and much broader than one medical drama. She had an early lead role in the NBC sitcom Three Sisters, which premiered in 2001 and ran for two seasons (IMDb biography). Her guest credits include Two and a Half Men, Justified, and Dynasty (Wikipedia biography).

Was Katherine LaNasa in Two and a Half Men, Justified, and Dynasty?

• Yes — all three shows appear in her credit list (Wikipedia biography).

Each of those roles is a guest credit, but together they show how steadily LaNasa worked across broadcast and cable television for years before The Pitt.

The pattern: she was a utility player for decades; The Pitt turned that utility into a starring showcase.

What is Katherine LaNasa doing now?

She’s acting. Since 2025, she has played Charge Nurse Dana Evans in HBO Max’s The Pitt, and the role won her the Critics Choice Award for Best Supporting Actress in a Drama Series. Her Instagram bio currently reads: “Actress, Activist, Designer, Mother, Maneater, Mrs Grant Show” (Instagram bio).

Is Katherine LaNasa still acting?

• Yes — since 2025 her current role is Charge Nurse Dana Evans in The Pitt.

The Critics Choice win is the cleanest marker of where she is now: the award is for a current performance, not a nostalgia credit.

The catch: what looks like a health headline is a TV plot; every current‑career fact points to acting, not illness.

Katherine LaNasa timeline

• 1966: Born December 1 in New Orleans, Louisiana (Wikipedia biography).
• 1989: Married Dennis Hopper at 22 (The Daily Beast report).
• 1992: Divorced Dennis Hopper (The Daily Beast report).
• 2004: Married Grant Show (Wikipedia biography).
• 2025: Premiered as Charge Nurse Dana Evans in HBO Max’s The Pitt.
• 2025: Received the Critics Choice Award for Best Supporting Actress in a Drama Series.

The pattern: the timeline is a second‑act story — long professional grind, a famous marriage, then an awards breakthrough at the point most actresses are written off.

What’s confirmed and what’s still unclear

What this means: search traffic will keep pulling up the Hopper years, but the evidence now points to a career that has outgrown them.

What the sources say

Actress, Activist, Designer, Mother, Maneater, Mrs Grant Show.

Katherine LaNasa, Instagram bio (self-published profile)

LaNasa reportedly met Dennis Hopper while touring in Los Angeles with Karole Armitage’s ballet company in 1987.

The List’s biographical profile (entertainment feature)

At the time of the marriage, LaNasa was approximately 22 and Hopper was approximately 53.

The Daily Beast’s report (news outlet)

The common thread: the sources agree that Hopper is the before, The Pitt is the after.

For audiences who found LaNasa through Grey’s Anatomy, Two and a Half Men, or the old Dennis Hopper headlines, the update is easy to miss. The Pitt fixed that: her Critics Choice win gives the actress a professional identity that no longer needs a famous husband as a modifier. Readers who like this kind of celebrity‑bio deep dive can also check our profiles of Mimi Rogers and Amanda Peet. For viewers, the choice is clear: start with The Pitt, or miss the best role of her career.
