Voice of the Month: Stephanie Cook — Leading With Trust, Equity, and Collective Power

Sep 18

At Women Speak Up, we celebrate women who understand that finding your voice is about more than being heard. It’s about what you choose to do once you have the confidence to speak. For Stephanie Cook, Executive Director of the San Diego Women’s Foundation, using her voice has never meant being the loudest person in the room. It means listening deeply, asking thoughtful questions, challenging assumptions, and making space for someone else to be heard. That philosophy is not something Stephanie learned from a leadership handbook. It grew from her own life being raised in a rural community in eastern San Diego County, from the people who invested in her when opportunities were not always equally accessible, and from the women who saw potential in her before she fully recognized it herself. Today, Stephanie is a mother of two, a lifelong San Diegan, and a nonprofit leader working to make philanthropy more equitable and responsive to the communities it is meant to serve.

Growing Up and Discovering What Community Can Make Possible

Stephanie grew up in rural eastern San Diego County, in a community where many families faced economic challenges and access to opportunity was not always equal. That environment gave her an early understanding that talent and potential can exist everywhere, even when opportunity does not. Her childhood taught her something else, too. Stephanie experienced what can happen when people intentionally invest in someone. Nonprofits and mentors supported her as a young woman, helping her develop confidence, find her voice, and imagine possibilities beyond those immediately visible to her.

“The nonprofits and mentors who invested in me as a young woman helped me find my voice and showed me what was possible when communities come together to support one another.”

For Stephanie, those relationships became evidence of something she would later build an entire career around: meaningful support is not about deciding what someone else needs. It begins with recognizing the strengths and possibilities that already exist within them. The people who invested in Stephanie did more than provide resources or encouragement. They expanded her sense of what was possible. Years later, she would work to do the same for others.

When Someone Else Sees Your Potential

As Stephanie grew older, her interest in women, power, opportunity, and social change took her to San Diego State University, where she earned her bachelor’s degree in Women’s Studies. There, she met someone who would become one of the defining mentors in her life: Dr. Doreen Mattingly, who led the university’s Women’s Studies Department. Dr. Mattingly did not simply teach Stephanie. She challenged her. She encouraged Stephanie’s research, pushed her to think more deeply about how social change happens, and became the first person to tell her that she should pursue a graduate degree. For a young woman still discovering where her voice might take her, that belief mattered.

“Her belief in me helped shape the path that ultimately led me to a career in the nonprofit sector.”

Stephanie went on to research the transformative power of women’s movements in graduate school, deepening her understanding of something she had already experienced personally, which is that lasting change rarely happens because of one individual. It happens collectively. Her relationship with Dr. Mattingly also reinforced the power of mentorship. Sometimes, finding your voice begins because another person takes the time to tell you that your ideas are worth exploring and your perspective is worth hearing. Stephanie has carried that lesson with her ever since.

Redefining What It Means to Use Your Voice

Leadership is often associated with confidence, authority, and having answers. Stephanie sees it differently.

“I believe that using your voice isn't always about speaking the loudest, it's often about creating space for others to be heard.”

That belief shapes how she leads today. Throughout her career, Stephanie has brought together people from different sectors, facilitated conversations between funders and community members, mentored emerging leaders, and helped women become more confident philanthropists.

Growing up, she saw how outside support could expand opportunity. As an adult, she has also learned that helping a community should never mean assuming you know more about its needs than the people who live and work there every day. Instead, leadership begins by listening.

Don't Wait Until You Feel Like an Expert

When asked what she would tell another woman still learning to use her voice, Stephanie does not tell her to wait until she feels completely confident, but rather she tells her the opposite.

“Don't wait until you feel like an ‘expert’ to speak up. Your voice has value because of your lived experiences, your perspective, and your willingness to learn.”

It is a message that speaks directly to one of the barriers many women encounter, which is the feeling that they need another credential, another accomplishment, or a little more experience before they have earned the right to contribute. Stephanie's journey challenges that idea. Finding your voice does not require knowing everything.

“Stay curious, listen deeply, ask thoughtful questions, and don't be afraid to change your mind when new information challenges your assumptions.”

There is strength in that kind of leadership, the kind confident enough to speak but humble enough to keep learning.

“Finding your voice isn't about having all the answers, it's about using your voice with purpose, humility, and compassion, and creating space for others to use theirs.”

What Being Voice of the Month Means

For Stephanie, being recognized as Women Speak Up’s Voice of the Month is meaningful because it represents something much larger than individual recognition.

“This recognition is incredibly meaningful because it reminds me that every voice has the power to create change.”

Stephanie immediately turns the spotlight outward and shares the love.

“I'm honored to be recognized, but I'm even more grateful for the opportunity to highlight the work of the many women, nonprofit leaders, and community partners who inspire me every day.”

That instinct, to receive a platform and then make room on it for others, may say more about Stephanie’s leadership than any title could. She hopes her story encourages women to speak up, but also to listen. To ask thoughtful questions, to lead with curiosity and compassion, and to recognize that using your voice is not only about advocating for yourself or the issues that matter to you. It can also mean helping someone else's voice travel farther.

Your Community Needs Your Voice, Too

Stephanie’s story does not end with an invitation to admire what she has accomplished. It ends with an invitation to participate. You do not need to run a foundation to strengthen your community or have every answer available. You can volunteer, mentor someone, join a giving circle, serve on a nonprofit board, and show up consistently for a cause that matters to you.

“You don't need to have all the answers or all the resources to make a difference.”

For the young Stephanie Cook, people in her community chose to show up. Nonprofits invested in her. Mentors encouraged her. One professor saw possibilities in her future and told her to pursue them. Those individual acts became part of something much larger.

Today, Stephanie is creating that ripple for others.

Her story reminds us that finding our voices is only the beginning. What matters is how we choose to use them, whether we use them to challenge an assumption, ask a better question, advocate for someone who is not in the room, mentor the next woman coming behind us, or simply listen when another person needs to be heard.

One voice can begin something.

As Stephanie has learned throughout her life, collective action has the power to create extraordinary change.
