When Sandra Forero stepped into her role as the chief operating officer of ZS in 2021, she achieved a milestone that is increasingly rare in the modern corporate landscape: she reached the C-suite without ever leaving the company where she began her professional career. Forero’s journey with ZS, a prominent global management consulting and technology firm, spans more than two decades. It is a trajectory defined not just by loyalty, but by the deliberate, patient cultivation of an organizational culture that she has helped shape since joining the organization as an intern in 2001 while concurrently pursuing her MBA. Her profound impact on the firm has not gone unnoticed externally either, having previously earned her a coveted spot on Consulting Magazine’s prestigious “Top 25 Consultants” list.
Yet, Forero’s remarkable path to leadership began thousands of miles away from corporate boardrooms and consulting engagements. She still carries vivid memories of making the monumental move to the United States from Colombia as a newly married immigrant. Arriving with virtually no financial resources and a toddler—a daughter just two and a half years old—she faced a reality that demanded absolute resilience. There were no shortcuts available, and certainly no room for hesitation or procrastination. Survival and eventual success required relentless hard work, strict personal discipline, and meticulous time management. Rather than allowing these early hardships to harden her emotionally or create a distant leadership style, those formative challenges forged her into a deeply capable, highly empathetic leader who understands the value of human perseverance.
That foundation of empathy and operational rigor has continuously informed her approach to large-scale business challenges throughout her career. Reflecting on a pivotal chapter from a dozen years ago, Forero recalls leading one of the firm’s most ambitious undertakings at the time. A major global client was undergoing a massive, highly complex organizational transformation, evolving into an integrated shared services organization for analytics and technology while simultaneously migrating to a brand-new cloud-based technology infrastructure. Forero, who served as the lead project manager for ZS, remembers feeling a profound sense of opportunity and privilege to be at the helm of such a sweeping enterprise.
The undertaking was far from easy, marked by intense moments of pressure and intricate logistical hurdles. However, those very difficulties ultimately forged a robust platform that allowed Forero to cultivate deep, enduring client relationships across multiple operational functions. More importantly, it enabled the consulting team to deliver tangible, high-impact results for the client organization. It stood as one of the earliest global implementations of its kind executed by ZS, serving as a powerful collaborative arena where subject-matter experts from across the firm had to synchronize their expertise to ensure program success. Looking back, Forero notes that the arduous experience acted as a launching pad, propelling the careers of numerous talented professionals within ZS while simultaneously driving transformative business value for the client.
Now serving as the firm’s chief operating officer, Forero channels that same passion for large-scale evolution inward. In her current executive capacity, she oversees key operational initiatives designed to continuously modernize the global management consulting and technology firm, ensuring that ZS remains firmly positioned on the cutting edge of industry standards and technological innovation.
At the core of her leadership philosophy is a deeply held sense of purpose that extends far beyond quarterly financial metrics or standard operational efficiency. Forero articulates this mission with striking clarity, emphasizing that the ultimate goal of the firm’s work is to fundamentally improve the human experience and elevate how people live and work. She acknowledges that this overarching vision can manifest differently depending on the individual, but for her, it provides an unwavering compass. Her primary commitment remains focused on delivering optimal impact for clients and helping them untangle their most difficult business problems, operating under the firm belief that if that core priority is consistently met, all other markers of success will naturally follow.
This intense dedication to positive impact is directed inward toward the ZS workforce just as strongly as it is outward toward clients. As the firm experienced rapid global growth and expansion, Forero and several of her colleagues recognized a looming threat: the distinctive culture that made ZS such a unique and effective place to work was at risk of diluting. They realized that the core tenets driving the organization’s success were not being translated, preserved, or evangelized at the same rapid pace as the firm’s physical and financial expansion.
To address this vulnerability, Forero proposed the creation of a dedicated worldwide team specifically tasked with defining, nurturing, and broadcasting the cultural pillars that had built ZS into the organization it is today. This initiative led to the founding of the firm’s People and Culture Team. While the underlying concept mirrored the foundational principles originally established by ZS’s founders four decades prior, Forero and her colleagues successfully re-engineered the framework for a modern, globalized era, ensuring that the distinctive elements making ZS special would endure and evolve rather than fade away.
The tangible strength of this shared culture was powerfully demonstrated during the height of the COVID-19 pandemic. When the global health crisis devastated communities around the world—hit particularly hard in India, where local medical resources were severely strained—ZS mobilized its global network and resources with remarkable speed. Leveraging the firm’s international partnerships and logistical capabilities, leadership worked tirelessly to locate and secure scarce medical supplies, including oxygen and ventilators, for ZS team members and their families who were facing desperate shortages on the ground.
While the relief effort in India stood out as the most significant logistical undertaking during that turbulent period, Forero notes with immense pride that the organization made the health, safety, and psychological wellbeing of all ZS employees a top global priority. She expresses deep pride in having been part of an executive leadership team capable of responding to an unprecedented global crisis with profound empathy, successfully providing vital extra support to their people during one of the most difficult chapters in modern history.
Forero’s institutional impact also extends directly into the realm of corporate governance and internal equity. She was a founding member and former chair of the ZS Inclusion and Belonging Council, a high-level governing body established to work in close partnership with the Shareholders’ Council—the firm’s board of directors—to cultivate an inclusive, high-performing workplace environment. This initiative marked another defining chapter in her tenure, as the council successfully advanced institutional policies and targeted programs designed to foster fairness, expand professional opportunities, strengthen diverse representation, and build a deeply engaged, empowered workforce.
To ensure these efforts yielded measurable progress, the newly formed team conducted comprehensive external benchmarking alongside rigorous internal analyses to pinpoint specific areas where ZS needed to improve its equity practices. They subsequently developed a concrete set of strategic recommendations and elevated the council’s institutional standing by establishing a direct reporting line to the firm’s Shareholders’ Council.
The council continues to operate actively within the firm today, carrying forward the vital mission of ensuring that as ZS diversifies its portfolio and project scope, the organization remains an authentic reflection of the wide array of skills, backgrounds, and human experiences necessary to drive complex problem-solving. Forero’s commitment to equity and leadership development also reaches beyond the corporate boundaries of her own firm. She maintains an active role in the broader professional community, serving on the Global Board of Directors for the Healthcare Businesswomen’s Association, where she currently holds the executive position of secretary and treasurer.
For anyone observing her career trajectory, a clear pattern emerges: whenever Forero identifies a systemic need within an organization or an industry, she steps forward to address it directly. It is a reflection of her authentic character and professional ethos, rooted in the simple yet demanding philosophy that she can only ever be entirely true to herself.
Elaborating on this personal leadership style, Forero explains that effective leadership requires complete authenticity, which means being willing to acknowledge mistakes, embracing personal vulnerability, and resisting the urge to project false omniscience. She places tremendous value on investing in the success of others, noting that building strong, capable teams not only drives superior business results but also provides the deeply satisfying experience of watching colleagues grow professionally. Collaboration remains a cornerstone of her daily routine, as she firmly believes that bringing the absolute best of ZS to clients can only be achieved by functioning as a unified team. She credits ZS with consistently providing her with the professional platform to execute this vision while remaining entirely authentic to who she is, cementing her long-standing loyalty to the firm.
What began decades ago as a challenging transition for a young immigrant couple moving from Colombia has steadily blossomed into a thriving life defined by strong partnerships both on and off the clock. Forero frequently highlights her husband, Mauricio, whom she describes as her best friend and the anchor of her personal life. She speaks with immense pride about their children, a daughter and a son whom she affectionately refers to as "Version 2.0"—improved iterations of herself and her husband. Despite her demanding executive schedule, she maintains daily communication with her siblings back in Colombia, who remain a continuous source of joy and grounding. Whether she is steering a global management consulting firm through complex operational transformations or nurturing her close-knit family, Forero has consistently demonstrated a rare ability to bring the right people together to build something enduring and extraordinary.
