Why Gary Lancz
Stands Out

Gary Lancz is the President of Ameritech Construction Corporation — and the #17 ranked home improvement CEO in the nation according to Power100's proprietary 5-layer evaluation system. With over 34 years at the helm of Ameritech since joining the company at its inception in September 1991, Gary has built one of the most respected home improvement companies in the Washington D.C. metropolitan area, serving homeowners across Maryland, Virginia, and the District of Columbia. Under Gary's leadership, Ameritech Construction has earned a reputation for sourcing and installing only the highest-quality home improvement products from manufacturers renowned for durability and energy efficiency. The company is the exclusive provider of several trusted brands in the Maryland, Virginia, and D.C. market — meaning no other contractor in the region can offer products of equal strength and long-term value. Ameritech's product line includes energy-efficient replacement windows, exterior doors, roofing, siding, insulation, trim work, decks, and gutter systems, all backed by professional installation from seasoned craftsmen with decades of experience. Gary's strengths include deep expertise in construction management, client relationship building, and the implementation of innovative technologies to streamline operations. He is known for his attention to detail and his ability to deliver projects on time and within budget, which has driven consistent repeat business and strong referral networks. Gary is also active in community service and charitable work, qualifying him for consideration in Power100's Charitable CEO of the Year Award. He holds a degree from the University of Maryland and also attended Drexel University. His LinkedIn skills include Sales Management and Home Improvement, with 20+ endorsements in Sales Management alone.
