Yet the scars from those insults haven't faded. In fact, she says she feels as if she's been transported back in time. Her school-age kids have been subjected to the same kind of comments that she endured decades ago.
But there's a big difference. Her children aren't staying under the radar, like she once did: "They're speaking up and saying something when they do get harassed and saying that's not appropriate."
A supportive school helps on that front. Huang has her own support network, too. Not just friends of Asian descent in the Raleigh-Durham area, where she grew up. But also at Cox Automotive, the parent of Manheim, and its Cox Enterprises parent.
It comes in the form of employee resource groups, known as ERGs.
The first, for women, started six years ago. One for the LGBTQ community followed. Another is for veterans. There are 11 in all. Huang is the executive co-sponsor of the Lotus Asian-American Pacific Islander group.
Her former boss and predecessor at Manheim, Janet Barnard, oversees ERGs as Cox Automotive's chief people officer. She says they have two main purposes.
They provide a place for people of common backgrounds and cultures to come together. They also provide a forum for all employees to listen and learn about cultural and topical issues — moderated discussions of police shootings, for example.
Another benefit is to help Cox itself grow. Members of a particular group might be asked to review marketing materials for cultural sensitivity.
It's all part of a Cox mission to build a culture of respect and engagement.
That spirit was reflected in a separate diversity and inclusion workshop that Cox held for executives last summer. There, Barnard saw the power of Huang's voice take root as she declared that staying silent was no longer the way to go.
It also stood out in her hosting of seven internal open-forum discussions on diversity starting last year. It was mirrored in a solidarity message about anti-Asian violence she co-authored in a March 19 memo to Cox employees.
And it was etched for the record in a listing of her name, along with those of hundreds of other business leaders, in a March 31 Wall Street Journal ad calling for an end to violence against Asian Americans.
Like Lee Wong, after years of silence, Grace Huang is speaking up.
As she said in a LinkedIn post this month: "Proud to stand with over 4000 Asian American business leaders and Allies in taking a stand against the hate, violence, and apathy directed at our community. ... We're just getting started."
