Marie Martineck is the Senior Director of Commercial Sales for CertaPro of Port Jefferson and brings more than 15 years of experience in the construction and building industry. Prior to her current role, she served as Vice President of Manhattan Signs for 13 years, where she developed strong leadership, sales, and operational expertise in a traditionally male-dominated industry.
Marie is an active member of the Long Island Builders Institute (LIBI), an organization of more than 700 members, and proudly serves as Co-Chair of the LIBI Women’s Committee. In this leadership role, she is dedicated to empowering, educating, and mentoring women while fostering meaningful professional connections within the building industry. She also serves as a mentor to multiple LIBI members, providing guidance, encouragement, and insight to help them grow and succeed professionally. The LIBI Women’s Committee is currently collaborating with the Girl Scouts of Suffolk County to create a mentorship program that will connect Girl Scouts with accomplished women in construction and related fields, introducing young women to career opportunities and leadership pathways in the industry.
Her commitment to leadership extends into her philanthropic work. Marie was honored to serve as a Visionary for the Leukemia & Lymphoma Society, where she assembled and led a team during a 10-week fundraising campaign to raise critical funds for blood cancer research and patient services. She is also actively involved with Long Island Home Builders Care, supporting community outreach efforts including gift drives, backpack drives, and volunteer initiatives.
One of Marie’s most meaningful roles has been serving as a Girl Scout Leader for six years at Maria Regina School in Seaford, where she led a troop alongside her daughter Gina. Through scouting, she helped young girls build confidence, resilience, leadership skills, and a lifelong commitment to service — values she believes are essential in shaping strong, capable women.
Marie’s dedication to service is reflected in her family. Her husband, John, is a Chief in the FDNY, and together they have built a life centered on leadership and giving back. Their daughter Gina, now a junior at St. Anthony’s High School, continues to embrace those same values by actively serving her community.
Marie is deeply committed to the Girl Scout mission of building girls of courage, confidence, and character who make the world a better place. She is honored to support and inspire the next generation of female leaders.
