“In facing challenges or change, I always go back to the questions: Am I in the right place? Am I surrounded by the right people? Am I learning? Am I growing?” says Johanna Diaz. “When you can identify core tenets to return to and hold yourself to them, they become a guide for navigating almost anything.”
Led as much by her intuition as by the foundational aspirations of her first-generation beginnings, Diaz leverages every opportunity to learn, grow, and lead. She shares how her trajectory reflects not only her resilience but also the support of mentors whose influence continues to inform her leadership.
From the Bronx to Goldman Sachs
Born in the Bronx to parents who immigrated from the Dominican Republic, Diaz understood the value of education from an early age: “being a first-generation American, my parents made it a priority for my siblings and me. We were the first in our family to attend university and enter the business world.”
For Diaz, that focus on education was also a path to financial stability, which led her to pursue accounting — a profession she saw as both practical and reliable. Starting her career first as an intern and then as a CPA at Grant Thornton, Diaz gained both skills and exposure. When she was first introduced to Goldman Sachs as a client of Grant Thornton, the experience left an impression.
“I was blown away by the caliber of the people, the rigor around collaborative teamwork and the focus on delivery.” That exposure opened her eyes to possibilities beyond what Diaz had imagined. When the opportunity came to join Goldman, she took the leap. “That was the first big twist in my career as it redirected my vision from accounting to a whole other world of possibility.”
Over the next two decades, Diaz’ career grew organically across business development, research, and ultimately asset management to be the Global Head of Alternatives Product Strategy, a role that she finds equally rewarding and inspiring.
“The last five years have been so incredible, pivoting to the alternative investing landscape. I’ve had the opportunity to help build a business from scratch and expand the shelf as it relates to our products. The content, as well as being a part of a team that is integral to Goldman Sachs’ growth has been so fulfilling.”
The Influence of Mentors and Executive Coaching
Diaz credits her ability to pivot, take risks, and grow in new roles as being bolstered by the mentors who offered guidance and perspective along the way. An early mentor gave her a piece of advice that still resonates: take stock every few years.
“That conversation was pivotal for me. Even 20 years later, every two to three years, I take a personal moment of deep reflection: Where am I? Have I accomplished what I set out to do? Could there be more? That practice has guided me throughout my entire time at Goldman.”
She sees mentors as a personal “board of directors” — people who know her well and can be honest when she calls on them for guidance, whether about career decisions or balancing family and work. “My mentors played a huge role in helping me navigate my personal journey, including building a family, while building momentum in my career.”
Executive coaching complemented that support, giving Diaz structured feedback and tools to grow. Early programs offered through Goldman helped her refine presentation skills, while later on she focused on refining “leadership and communication skills but in a more nuanced way than I’d ever had before.”
Together, mentorship and coaching have provided Diaz with both a trusted sounding board and a framework for continuous growth, shaping the leader she is today.
Values-Driven Leadership
Beyond the mentors and coaches who helped guide her, Diaz points to a foundation of authenticity and integrity as key to her success.
“First and foremost, it’s important to remain true to yourself,” she says. “All of my values anchor around being a good human and working with high integrity. They guide me through everything I do.”
Fairness is equally central. Diaz strives to create a work environment where people feel valued, connected, and confident that they will be treated justly. “I want to be someone people feel comfortable approaching,” she explains. “They should know I’ll listen and provide support.” Drawing on lessons from leaders she has worked with, Diaz shapes her leadership around trust, relationship-building, and followership.
Hard work and high standards also define her approach. She believes in delivering quality work with reliable outcomes and modeling excellence to inspire her team to do the same. “As a baseline, I expect that not only of myself, but it’s also important to me to set the right example that my team then wants to follow,” she notes.
Embracing Risk
While Diaz’s career has been marked by achievement, it has not been without moments of uncertainty. She recalls these moments as an opportunity to pause and reflect.
“Early on, I faced a decision about whether to continue in research or move toward a more strategic, leadership-focused role. It was uncomfortable because I wasn’t sure I’d excel, but I leaned on my core values and trusted mentors to guide the decision.”
Over time, Diaz has learned to embrace risk thoughtfully, viewing it as an opportunity to challenge herself and explore new possibilities. Her recent transition into asset management illustrates this approach. Encouraged by a mentor to consider another part of the firm, she reflects, “it was through that conversation that I realized that it was time to take a risk. I was super comfortable. I had a lot of security. I had to consider, ‘do I want to push myself a little more?’”
Deciding to “take a risk on herself” and accept the opportunity to become the COO of Goldman’s growth business, Diaz says, “was a big transition. But it pushed me, and it’s been the most pivotal part of my career.”
Legacy of Access and Opportunity
Looking ahead, Diaz is focused on creating opportunities for others to grow, much like she was supported throughout her career. “I hope to provide a platform for the teams I work with, and for the junior professionals I mentor, where they have access, exposure, and opportunity the way I did.”
Reflecting on her own journey, Diaz acknowledges how her first-generation roots are a part of shaping this commitment. “We really have lived the proverbial American dream. My parents grew up on a farm — my mom one of 12 kids, my dad one of nine — and through a combination of hard work, timing, and a little luck, we’ve seen growth that isn’t just financial. It’s also about access to the world, to opportunities that otherwise wouldn’t have been organic. It’s important to me and my family to pay it forward.”
Thanks to the holistic support embedded in Goldman’s culture, Diaz also makes an impact beyond the firm through programs like 10,000 Small Businesses. “Having the opportunity to serve as a mentor in the program, I have listened to small business owners’ pitches and given feedback—providing people with access that they otherwise wouldn’t have.”
Ultimately, Diaz measures her legacy by the people she supports. By combining high standards, integrity, and a values-driven leadership style, she aims to cultivate talent, inspire confidence, and foster a culture where people feel valued, challenged, and capable of achieving their potential.
“If, 20 years from now, I can look back and see that the people I touched built successful, meaningful careers, then I’ll know I’ve done my part.”
