Warren Buffett's granddaughter-in-law takes up role at JPMorgan's wealth management division

• Warren Buffett's granddaughter-in-law just joined JPMorgan as a wealth advisor.
• Lili Buffett took up the new role on Monday, according to an Instagram post.

The granddaughter-in-law of billionaire investor Warren Buffett joined JPMorgan as one of its newest employees on Monday.

Lili Buffett, 36, who's married to Howard Buffett, the grandson of the Berkshire Hathaway CEO, took up a role as a wealth advisor. She will be focusing on its clients' foundations and philanthropy, according to an Instagram post by Liz Weikes, a managing director and wealth partner at JPMorgan.

"Lili brings a wealth of knowledge in the philanthropic and foundation space and will be a tremendous asset to The Weikes Group. I couldn't be prouder for Lili to grow as a Wealth Advisor and fellow working mother alongside me," Weikes wrote in a post under a photo of the pair.

Lili also publicized the news in an Instagram story on Monday, where she wrote "First Day!" on a photo of herself standing outside a JPMorgan office. Before that, she wrote "Can't wait to shop for work attire for my new career at JP Morgan," in a September 13 post.

Warren Buffett has been a longtime fan of JPMorgan's CEO, Jamie Dimon, and has praised him many times in recent years. In 2011, Buffett described him as a "fabulous banker" to Bloomberg and a "first-class guy" to the Financial Times in 2014.

The famed investor also defended Dimon's pay rise in 2013, saying: "If Jamie decides he wants to make more money, all he has to do is call me and I'd hire him at Berkshire," he told The Wall Street Journal.

Dimon and Warren Buffett have worked together in the past, such as when they partnered with Amazon's former CEO Jeff Bezos to launch Haven, a healthcare venture focused on providing better and cheaper care for their employees. But the venture eventually failed three years after launching.

As well as being an ally of Dimon, Warren Buffett is also an admirer of his bank JPMorgan, where Berkshire Hathaway built a stake worth more than $8 billion at its peak. But in a surprise sell-off in 2020, Berkshire slashed its holding to fewer than 1 million shares worth less than $100 million.
