David Mallette is the Owner and CEO of The Window Source of Houston, a U.S. Marine Corps veteran, and an accomplished business and sales leader with nearly 20 years of experience in the glass, glazing, window, and door industry. His expertise spans residential and commercial markets, national sales leadership, business development, operations, installation systems, team building, and customer experience. Before founding The Window Source of Houston, David built his career in the commercial glass and glazing industry and held national sales leadership positions with major corporations, including Eaton Corporation. As a National Sales Manager, he gained extensive experience developing sales strategies, managing large territories, building high-performing teams, growing key accounts, and creating long-term relationships with customers and industry partners across the country. His combination of corporate sales leadership and hands-on industry experience gives David a unique perspective on growing a business. He understands both the technical side of the industry and the systems, people, accountability, and sales processes required to scale an organization successfully. Today, David applies that experience as Owner and CEO of The Window Source of Houston, where he leads the company's continued growth throughout the Greater Houston market. His focus is on developing high installation standards, building strong sales and operations teams, creating a straightforward, no-pressure customer experience, and delivering exceptional long-term value to homeowners. David's leadership philosophy is also deeply influenced by his service in the United States Marine Corps. The principles of discipline, accountability, integrity, leadership, and taking care of your people continue to shape how he operates his company today. He believes sustainable growth comes from surrounding yourself with great people, developing strong systems, maintaining high standards, and never sacrificing your reputation for short-term results.
