I attribute my success to staying curious, being willing to learn from every experience, and trusting my own voice as a leader. Early in my career, I realized that results come not just from hard work, but from empowering others, creating clarity, and fostering a team environment where people can succeed day after day. By focusing on collaboration, integrity, and continuous improvement, I’ve been able to grow both as a leader and as a person.

The best advice I ever received was to “couch my honesty.” Early in my leadership career, a former distribution center manager challenged me to find the right balance between transparency and clarity. I learned that while teams need honest communication to succeed, too much information—especially details that don’t affect their day-to-day work—can create confusion, distraction, or unnecessary doubt. Keeping communication simple, specific, and relevant builds clarity, maintains focus, and allows leaders to spend more time guiding the team rather than managing noise.

Learn the operation from the ground up. Spend time understanding how work actually moves—on the floor, in the field, and across systems—because credibility in this industry comes from knowing the details and how they connect. Don’t shy away from challenging assignments, night shifts, or problem areas; those experiences accelerate growth and build confidence. Speak up, ask questions, and trust your perspective. You don’t need to match anyone else’s leadership style—consistency, preparation, and follow-through matter more than perfection.

Effective leaders in operations succeed in different ways—some are direct, some are collaborative, some are quiet problem-solvers. What matters is being consistent, prepared, fair, and accountable. Lead in a way that aligns with your strengths while delivering results.

The biggest challenge in operations and supply chain is balancing efficiency with complexity—navigating labor shortages, fluctuating demand, and compliance pressures—while still delivering excellent service. For women entering the field, this environment is also an opportunity: to bring fresh perspectives, lead process improvements, and leverage data and technology to drive measurable results. By building adaptable, high-performing teams and trusting their own leadership style, emerging leaders can turn these challenges into opportunities to make a real impact on both operations and organizational culture.

Integrity, accountability, and consistency are central to both my work and personal life. I value honesty and transparency in communication, follow through on commitments, and strive to lead by example. Collaboration and respect for others’ perspectives are also important, because strong relationships and trust are the foundation for high-performing teams. Finally, continuous learning and improvement guide me—professionally, I seek opportunities to optimize processes and mentor others, and personally, I focus on growth and balance in all areas of life.
