Jerome Villanueva, 32

Owner and Barber, IV

Lives: Vallejo

Works: Hercules, Vallejo

As a child growing up in San Francisco, Jerome Villanueva was fascinated by street art. "Something about the lines, symmetry, and shading has always grabbed my interest," he reminisces. But pursuing his passion for graffiti led to some run-ins with the law—which convinced Villanueva to shift his direction.

"I watched a lot of ’90s gangster movies like Boyz n the Hood, Menace II Society, or Paid in Full," he says. "The moment I saw the fades and designs on their heads, I knew this would be my new outlet for art."

Villanueva has since opened two barber shops: IV Lounge in Vallejo and IV Salon and Barber in Hercules. The salons are known not only for their expert haircuts but also for their community engagement. He partners with nonprofits and donates his businesses’ services to the homeless, underserved families, survivors of abuse, and more.

"[I am] thankful to [connect] my profession as a barber with my true passion," Villanueva says. "[You] find yourself in the act of serving others." —Morgan Mitchell

Author, The Tsar of Love and Techno and A Constellation of Vital Phenomena

Lives/Works: Oakland

When you imagine the life of a writer, you most likely don’t think of Tom Hanks’ character in the 2000 movie Cast Away. But Anthony Marra—author of the New York Times best-selling novel A Constellation of Vital Phenomena and the collection of short stories The Tsar of Love and Techno—says the comparison is pretty apt.

"Writing is by definition a solitary pursuit; most of my time is spent alone in front of the keyboard," he says. "Sometimes, this makes me feel a little like Tom Hanks, talking to volleyballs and coconuts. Every book is a boat you build to take you far away … but for most of the writing process, you’re marooned."

Marra’s books are certainly reaching people. Most recently, he received the 2018 Simpson Family Literary Prize. Tsar was also a​ finalist for the National Book Critics Circle Award, and Constellation was long listed for the National Book Award and won the National Book Critics Circle’s John Leonard Prize. —M.M.

Lives/Works: Oakland

When a friend or family member faces a life-changing moment, many people rush to buy them a card, only to find corny options. But what do you say to a coworker who recently lost a parent? Or a sister undergoing chemotherapy? Or a friend in rehab? That’s where Thoughtful Human comes in.

"Thoughtful Human takes a radically different approach to the $8 billion card industry, challenging people to stop buying cheesy cards and to start using them to communicate in ways that are more meaningful," says CEO Ali O’Grady.

The UC Santa Cruz alum started her series-based card company last year after noticing people struggling to talk about difficult topics, such as grief, illness, depression, and addiction. So, she developed a product that provides consumers with creative, sincere ways to express themselves and start a dialogue about sensitive issues. O’Grady knows all too well how hard those conversations can be: She lost her father to cancer in 2011 and has several friends and relatives who’ve struggled with substance abuse.

"All Thoughtful Human content was inspired by my personal experiences and shaped by people from [different regions]," she says. "The stories they’ve shared have blown me away and continue to motivate me."

The e-commerce site also partners with nonprofits and prioritizes environmental responsibility. In fact, all Thoughtful Human cards are biodegradable and made from plantable paper embedded with wildflower seeds.

This combination of sustainability, transparency, and empathy seems to resonate with consumers. In the past 11 months, O’Grady has grown her customer base and started selling her cards at local retailers (such as Berkeley’s Whole Foods and Walnut Creek’s Bondadoso Coffee and Tea Collective) and on Target​.com. —Alejandra Saragoza

For many people, a stint in prison is a negative transformative experience. For Dennis Dumas Jr., his three-year sentence for burglary and armed robbery catapulted him on an unlikely journey that included founding a growing fitness-club franchise.

After establishing his own electrical contracting business in Southern California, he began using cocaine and meth, eventually financing his drug habit through robberies and other crimes—which landed him behind bars.

When Dumas started his sentence in 2005, he was an out-of-shape addict trying to quit cold turkey. Exercising helped him adapt to prison life and develop theories that inform his fitness philosophy today. He created a blind cueing technique, for example, while leading group workouts in near isolation in Chino’s California Institution for Men’s administrative segregation unit—where prisoners were allowed out of their cells for only one hour a month.

"Movement of our bodies [reflects the] universal empathy we have for one another," Dumas says. "It eliminates a lot of barriers; socioeconomic status, age, race—all of it goes away when everyone starts to move and challenge their bodies."

After serving his time, Dumas started working in the fitness industry, eventually opening his own studio, Omni Fight Club, in Livermore in 2016. He has since expanded to Pleasanton and Walnut Creek, and also founded a management and consulting firm called DFIT Enterprises.

Community is at the heart of Omni Fight Club, which supports local schools and youth programs. "I’ve done a lot of bad stuff, and I owe it to my community to give back," Dumas says. "The social impact we have on our community is so important … That is our biggest win." —R.O.

In 2013, Google’s Machine Intelligence group (now known as Google AI, or artificial intelligence) was hardly a guaranteed success. Irina Kofman—who then worked as part of Google’s core Search team—was completing her master’s degree and had a three-year-old at home. She knew joining this fledgling department would be a risk.

"At that point, very few companies had an effort in AI; it was kind of an unknown," Kofman says. "It was even hard to convince people internally at the company [to support the AI project]. I went back and forth on taking the risk or not."

She still recalls the wise words of a coworker who ultimately helped her make the decision: "When your job gets easy, do something hard."

In that moment, Kofman remembers saying to herself: "OK, I’m not sure this will work, but I know it will be hard. And I don’t want to miss out on the chance to work on a technology that could change the future lives of my kids and family."

Taking that leap of faith to improve the lives of her loved ones felt particularly significant to Kofman. She and her family escaped religious persecution in Ukraine and fled to America as refugees when she was five years old—an experience that continues to drive her. "There’s this immigrant mentality that, to succeed, you have to work very, very hard," she says. "I saw the work ethic my parents had to bring to enable my sister and me to have these opportunities. Every single choice I make, that’s in the back of my head."

Five years after signing on to the venture, Kofman’s decision has paid off. Today, she oversees day-to-day operations for all things AI at Google and has built an industry-leading training program for developing talent in the field. "[We are] working to … bring the benefits of AI to everyone," she says. —M.M.

There, Pulupa’s receiver will measure solar plasmas (or gases).

When asked what she hopes to accomplish before age 40, Mandy Fields, chief financial officer of the specialty-beverage corporation BevMo!, has to think. "I wanted to be a CFO by the time I turned 40, and I was able to make that happen at 35 years old," she says. "I actually had people tell me it wouldn’t happen before 60. Can you imagine? You can’t let your reality be limited by someone else’s limited view of the world."

Fields definitely keeps her eyes wide open. At BevMo!, she oversees all finance-related decisions, including accounting, pricing, and inventory management. Her professional success has led the San Francisco Business Times to name Fields on its 2017 list of the Most Influential Women in Bay Area Business and Progressive Grocer to hail her among the Top Women in Grocery in 2016.

"There is always room for improvement," Fields says of her accolades and success. "The drive to always be better is what keeps me going." —M.M.
