SANTA BARBARA, CA, September 09, 2026 /24-7PressRelease/ -- Matthew LeMiere has been selected for inclusion in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.

Mr. LeMiere has established a distinguished career in cybersecurity, public sector technology and nation-state threat intelligence, earning recognition for his ability to build and scale organizations from the ground up. Since 2024, he has served as vice president of public sector at Semperis, where he leads a national team of sales professionals dedicated to protecting government agencies, educational institutions and communities from sophisticated cyber threats. In this capacity, Mr. LeMiere is responsible for meeting regional sales targets, driving new business, securing customer accounts and ensuring the proper implementation of systems to keep clients fully protected and satisfied. He also serves as a steward of technology by coordinating educational presentations on cyber threats with prominent board experts—including a former US General and the former head of cybersecurity at the National Security Agency—delivering critical insights to colleges, universities, school systems and government entities nationwide. Reporting directly to the head of Americas sales and the chief revenue officer, he oversees sales forecasts and performance metrics while maintaining a client-first approach that prioritizes eliminating threats before discussing partnerships or payment.

Before joining Semperis, Mr. LeMiere spent nine years at CrowdStrike, where he was instrumental in launching and leading the public-sector organization as its first state, local and education (SLED) sales representative. Beginning in 2016 as regional sales manager for SLED Western USA in Sacramento, California, he advanced to director of sales for SLED West in 2018. During his tenure, Mr. LeMiere grew the business from $1 million in annual revenue during its inaugural year to more than $100 million annually by the time of his departure in 2024. His leadership was pivotal in enabling government agencies—often lacking sufficient staffing or expertise—to access cutting-edge cybersecurity solutions.

Before his achievements at CrowdStrike, Mr. LeMiere served as regional director of sales for government, healthcare and education at Tanium Inc. in Sacramento from 2015 to 2016 after initially joining as regional sales manager in 2014. At Tanium, he again pioneered efforts to introduce advanced technology to public-sector clients, driven by a commitment to community service. He left Tanium only after being offered an opportunity at CrowdStrike to build a larger organization.

Earlier in his career, Mr. LeMiere worked at Palo Alto Networks from 2012 to 2014 as regional sales manager for government clients. There, he became the company's first dedicated SLED salesperson in California, establishing a structured approach that transformed sporadic commercial efforts into a robust public-sector operation. His foundational work contributed significantly to Palo Alto Networks' emergence as a major force in cybersecurity.

In 2014, Mr. LeMiere also held the role of client executive for U.S. public sector sales with Cisco Systems Inc., focusing on the State of California from Sacramento. Before that, he gained valuable experience as a senior named account manager at Juniper Networks Inc., further developing his expertise in technology solutions for government entities.

Throughout his career, Mr. LeMiere has demonstrated an exceptional ability to enter organizations with no prior government presence and build them into multimillion-dollar operations. This repeatable achievement stands as his most notable professional accomplishment. His expertise is widely recognized within the industry, particularly regarding nation-state threat intelligence and public sector cybersecurity.

Mr. LeMiere is an active member of several professional organizations, including the Municipal Information Systems Association of California and ISACA. He also maintains a lifelong connection with Phi Delta Theta Fraternity, having served as president during his college years—a role that continues to foster meaningful relationships within his personal and professional life.

His academic foundation includes a Bachelor of Arts degree in law and society with a concentration in criminal justice from the University of California, Santa Barbara, earned in 1993. This education provided him with critical analytical skills and an understanding of legal frameworks essential to navigating complex regulatory environments in cybersecurity and public-sector technology. He has further enhanced his qualifications through various cybersecurity certifications and specialized training programs in sales and leadership.

Mr. LeMiere attributes his professional success primarily to grit and resilience—a mindset shaped by early experiences overcoming adversity both academically and athletically. Elected captain by his peers on high school football teams and later serving as fraternity president despite setbacks, including injuries that ended his college athletic career, he developed a strong work ethic and pride that have defined his trajectory. When faced with challenges such as company closures or industry disruptions, he consistently views obstacles as opportunities for advancement rather than deterrents.

Beyond his professional pursuits, Mr. LeMiere is deeply committed to civic engagement and charitable initiatives. He supports organizations such as the Veterans of Foreign Wars, various fraternal groups, the Special Education Foundation, and Special Olympics—motivated in part by personal connections within his family—and participates annually in major September 11 fundraising campaigns through the Los Angeles chapter.

In his personal life, Mr. LeMiere enjoys boating, whale watching along the Santa Barbara coast, playing golf and hiking—activities that reflect his appreciation for nature and commitment to maintaining an active lifestyle. Family remains central to his life; he is married with three daughters whose ages span nearly two decades. Welcoming a child later in life has given him a renewed perspective on parenting while also presenting new challenges.

Looking ahead, Mr. LeMiere's aspirations focus on achieving financial security for himself and his children so he can dedicate more time to volunteer work and mental health initiatives, a cause inspired by his daughter's journey overcoming severe anxiety through innovative medical technology now used worldwide.

Mr. LeMiere's enduring legacy is marked by transformative leadership across multiple organizations, unwavering dedication to community protection through cybersecurity innovation and steadfast commitment to service, qualities that have earned him distinction among industry peers and inclusion in Marquis Who's Who.
