Jennifer Sierra

Jennifer Sierra is a Business Operations Leader at NASA's Jet Propulsion Laboratory (JPL), where she has spent more than 25 years partnering with executive leadership to strengthen business operations, lead strategic initiatives, and help organizations navigate change across complex, mission-driven environments. Growing up in a family deeply connected to JPL, she developed an early appreciation for innovation, collaboration, and the power of people working together to accomplish extraordinary things.

Driven by a lifelong passion for learning and helping others grow, Jennifer pursued her Master of Science in Management and Leadership at Pepperdine University. The experience further strengthened her passion for leadership development, emotional intelligence, and helping people grow both personally and professionally. It also inspired a new chapter as the founder of JenniferSpeaks.net, where she encourages individuals and organizations to embrace authenticity, overcome self-doubt, and lead with confidence and purpose.

Jennifer currently mentors employees through JPL's BuddyUp Program, serves on the JPL GUILD Committee, and co-founded the JPL Mindfulness Club in 2018 to foster connection and well-being in the workplace. She is known for bringing people together, building meaningful relationships, and creating environments where people feel supported, valued, and inspired to grow.

Whether supporting a NASA mission, mentoring a colleague, or speaking to an audience, Jennifer is driven by one purpose: helping people discover their strengths, grow in confidence, and realize more of what's possible within themselves. She believes leadership is measured not by titles, but by the lives we influence, the relationships we build, and the positive impact we leave behind.
