Days after the "Grey's Anatomy" actor died from ALS, his wife took to social media to thank those who have shown support.

"I am so blown away by the outpouring of love and support from our community," Rebecca Gayheart wrote via her Instagram Stories. "There aren't words to express our gratitude."

"You are truly holding us up during this difficult time," she said.

Born and raised in San Francisco, California, Dane kick-started his career in the early 1990s with small guest roles in beloved sitcoms such as "Saved By the Bell" and "The Wonder Years." It wasn't until 2000 that he landed his breakthrough role as Jason Dean on "Charmed," which he portrayed during the show's third season. 

Dane's professional life took a dramatic turn, however, when he made his debut as Dr. Mark Sloan ("McSteamy") on "Grey's Anatomy" in 2006.

After his run on "Grey's Anatomy," Dane took on the leading role of Capt. Tom Chandler on the TNT series "The Last Ship" from its premiere in June 2014 through its final season in 2018.

He later appeared in "Euphoria," "Kabul," "Countdown" and "Brilliant Minds."

Dane revealed he'd been diagnosed with ALS in April 2025.

During an interview on "Good Morning America" in June 2025, Dane said he was prepared to go to great measures to fight ALS.

"I will fly to Germany and eat the head off a rattlesnake if [doctors] told me that that would help," he told Diane Sawyer at the time. "I'll assume the risk."

Dane left his daughters with his heartbreaking advice in a pre-taped interview for Netflix's "Famous Last Words" series.

"Billie and Georgia, these words are for you," Dane said to his daughters in the November 2025 interview that was released the day after his death.

"I tried. I stumbled sometimes, but I tried. Overall, we had a blast, didn't we?" he said before getting choked up while recounting all the moments they shared together. "I see you now playing in the ocean for hours, my water babies. Those days, pun intended, were heaven. I want to tell you four things I've learned from this disease, and I hope you don't just listen to me. I hope you'll hear me."
