The SEMA Businesswomen’s Network (SBN) is proud to highlight two outstanding members who were selected as 2025 Women MAKE Award recipients: Tiffanie Hartenstein of Oracle Lighting and Alex Parker of Redline Detection. Presented by the Manufacturing Institute, this prestigious national honor recognizes exceptional women in manufacturing who demonstrate leadership, innovation, mentorship and a strong commitment to advancing the next generation. This select group is also recognized as emerging leaders, representing rising talent shaping the future of the industry.
Tiffanie Hartenstein
When Hartenstein learned she had been selected as a Women MAKE Award honoree, she felt both humbled and exhilarated. To her, the recognition served as validation of years of determination, innovation and a commitment to challenging the norms of a traditionally male-dominated industry. Personally, it reinforced the value of her passion and perseverance; professionally, it strengthened her drive to push boundaries and lead with purpose.
As CEO of Oracle Lighting, Hartenstein has guided the company to repeated appearances on the Inc. 5000 list through a leadership approach rooted in resilience, vision, empathy, authenticity and collaboration. Her commitment to innovation combined with strategic planning and a people-first philosophy has enabled Oracle to grow sustainably while remaining agile amid rapid market shifts.
Hartenstein’s leadership was shaped in part by navigating complex operational challenges during transformative industry moments. Through clear communication and steady decision making, she strengthened both her team and her own leadership capabilities. Those experiences deepened her commitment to building resilient organizations where innovation and empowerment thrive.
Mentorship plays a central role in her work. Influenced by mentors who challenged and supported her early in her career, Hartenstein now creates spaces for others to learn, grow and contribute confidently. She actively fosters open dialogue, celebrates individual contributions and ensures emerging leaders, especially women, have access to the guidance and opportunities they need to succeed.
Looking ahead, Hartenstein is energized by the future of manufacturing, driven by technology, sustainability and new workforce dynamics. She sees immense opportunity for women to lead in innovation, strategy and problem solving—areas where diverse voices fuel transformational progress.
Her advice to young women is powerful: Stay curious, build your network, and advocate for yourself. Every challenge is a chance to grow.
Alex Parker
When Parker learned she had been selected as a Women MAKE Award honoree, she felt surprised and thrilled, especially because the recognition aligned with her passion for developing future talent. Having mentored 127 student interns, she views the award as a meaningful affirmation of her work in advancing the next generation of female talent.
A bold and decisive leader, Parker embraces discomfort as a catalyst for growth. She credits her success to doing the work, knowing the mission and taking confident action—an approach that proved essential during the COVID era, when she guided Redline Detection through uncertainty with both compassion and clarity. Under her leadership, the company stayed fully operational, doubled in size and launched an entirely new business segment.
Her forward-looking vision also drove Redline’s evolution from mechanical to software-based diagnostic technology. By tracking global trends in powertrain innovation and investing early, her team developed breakthrough leak detection solutions now used by EV-native and legacy OEMs in 160 countries.
Parker’s mentorship philosophy centers on transparency, which involves teaching interns how she thinks and makes decisions, helping them build confidence and capability. She encourages more women to pursue technical career paths, noting that organizations with women on leadership teams are more profitable, more innovative and more resilient.
Her advice to young women? “Be ravenously curious… and have a bias for action.” Growth comes from stepping forward before you feel fully ready and embracing every opportunity to learn.
