Tamera Fenske is the chief supply chain officer (CSCO) for Kimberly-Clark, who oversees a massive global team of 22,665 employees—around 58% of the global CPG manufacturer’s workforce. She’s in charge of optimizing the company’s entire supply chain, from sourcing raw materials for Kimberly-Clark products including Kleenex and Huggies, to delivering the final product into customers’ shopping carts. 

It’s a job that’s essential to most top businesses operating at such a massive scale; around 422 of the Fortune 500 have chief supply chain officers, according to a 2025 Spencer Stuart analysis. However, most of these slots are awarded to white men; only about 18% of executives in this position are women, and 12% come from underrepresented racial and ethnic backgrounds. It’s one of the C-suite roles with the least female representation, right next to chief financial officers, chief operating officers, and CEOs. 

In fact, Fenske is one of around 76 Fortune 500 female executives who have “chief supply chain officer” on their resumes. However, the executive tells Fortune it’s an unfortunate fact she “doesn’t think about” too often—if anything, it motivates her further.

“Anytime someone tells me I can’t do something, it makes me want to work that much harder to prove them wrong,” Fenske says. 

The first time Fenske noticed she was one of few women in the room

Fenske has spent her entire life navigating subjects dominated by men—something she didn’t even consider until college. 

Her grandpa, aunt, uncles, and brother all worked for Dow Chemical, so she grew up in a STEM-heavy household. Naturally, she leaned into math and science as well, eventually pursuing a bachelor’s in environmental chemical engineering at Michigan Technological University. It was there that her eyes first opened to the reality that she was one of few women in the room. 

“It definitely was going to Michigan Tech, where I first realized the disparity,” Fenske said, adding that there was around an eight-to-one male-to-female ratio. “As you continue through the higher levels and the grades, it becomes even tighter, especially as you get into your specialized engineering.” 

Once joining the world of work, it wasn’t only Fenske who noticed the lack of women in senior roles—some bosses would even point it out. 

The Fortune 500 boss is paying it forward—for both men and women

After Fenske graduated from Michigan Tech, she got her start at $91 billion manufacturer 3M: a multinational conglomerate producing everything from pads of Post-It notes to rolls of Scotch tape. Fenske was first hired as an environmental engineer in 2000. Promotion after promotion came, but some people seemed to focus on her gender.

“It would come to light when I moved relatively quickly through the ranks. Some of my bosses would say, ‘You’re the age of my daughter,’ and different things like that. ‘You’re the first woman that’s had this role at this plant or in this division,’” Fenske recalls. Over the course of two decades, she rose through the company’s ranks to the SVP of 3M’s U.S. and Canada manufacturing and supply chain. 

And anytime she was asked about her gender? She’d flip the questions back at them while standing her ground. “I would always try to spin it a little bit and ask them questions like, ‘Okay, so what is your daughter doing?’…I always try to seek to understand where they are coming from, but then also reinforce what brought me to where I am.”

Now, three years into her current stint as Kimberly-Clark’s CSCO, the 47-year-old is paying it back—but not just to the women following in her footsteps.

“I never saw myself as necessarily a big, ground-breaker pioneer, even though the statistics would tell you I was,” Fenske says. “I tried to give back to women and men, to be honest. Because I think men [are] one of the strongest advocates for women as well. So I think we have to teach both how to have that equal lens and diverse perspective.”
