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, Marie served as Vice President of Manhattan Signs for 13 years, where she built a strong foundation in leadership, sales, and operations within a traditionally male-dominated field.
Marie is an active and committed member of the Long Island Builders Institute (LIBI), an organization of over 700 members. She proudly serves as Co-Chair of the LIBI Women’s Committee, which is dedicated to empowering, educating, and supporting women in the building industry. In addition, she mentors new LIBI members, helping them navigate the organization and build meaningful professional connections.
Giving back to the community is a core value for Marie. She is involved with LIBI’s charitable organization, Long Island Home Builders Care, volunteering at the Inn in Hempstead, organizing gift drives for children during Christmas and Easter, and supporting the annual backpack drive each August.
Marie is especially passionate about supporting the Girl Scouts because she believes in the organization’s mission to build confidence, leadership skills, and independence in young girls. She loves that Girl Scouts encourages girls to explore new opportunities, give back to their communities, and believe in their ability to succeed in any field they choose—values that have guided Marie throughout her own career and life.
Above all, Marie is a devoted mom to her amazing daughter Gina and a proud wife to her wonderful husband John, with whom she has shared 20 years of marriage. She is honored to share her experience with the next generation of leaders and hopes to inspire girls to dream big, work hard, and support one another along the way.
