Power100 is a national publication that has narrowed down the Nation’s top 100 CEOs. Our exclusive database boasts a formidable 7,600 CEOs, and after scouring through them all with our 5-layer proprietary ranking system, we proudly announce Owner and President Doug Cook as the #27 CEO in the country.

Doug Cook is the Owner, President, and Chairman of Feldco Windows, Siding, Doors & Roofing, the Midwest’s leading window, siding, and door replacement specialist. Founded in 1976, Feldco is a family-owned exterior remodeling company that has proudly served homeowners across Illinois, Indiana, Wisconsin, and Iowa for nearly 50 years, transforming over 500,000 homes with energy-efficient windows, vinyl siding, exterior doors, and roofing solutions.

Doug holds a Master of Business Administration from Northwestern University (1996-1998), which has provided him with the strategic foundation to scale Feldco into a regional powerhouse. His educational background, combined with his entrepreneurial experience—including previous roles at Danley’s Garage Builders, Vertical Chimney Care, and LiveWatch Security—has equipped him with diverse expertise in home services and business leadership.

Doug Cook possesses exceptional strengths in strategic growth, brand building, and creating a customer-centric corporate culture. His commitment to “Customer Delight” has become the defining characteristic of Feldco’s operations, where employees’ compensation is directly tied to customer ratings—a practice that engages everyone within the company to do their best every day.

Doug’s leadership philosophy emphasizes expansion during challenging times. While other companies scaled back operations during economic downturns, Doug opted to expand Feldco, opening several new locations and entering new markets. This counter-cyclical approach has positioned Feldco as the dominant player in the Midwest home improvement market. His vision extends beyond a single company—under his leadership, Feldco and sister company Danley’s, with over 100 years combined in the home improvement industry, have created a collection of companies that continue to grow.

His ability to build an iconic regional brand is evident in Feldco’s household name status throughout Chicagoland and the Midwest. From the catchy jingle and well-known phone number to the company’s familiar spokesman Dave, Doug has created marketing that resonates with consumers. His focus on factory-direct pricing and premium products has established Feldco as the company homeowners turn to when looking for the best value and experience in home exterior projects.

Under Doug Cook’s ownership and leadership, Feldco has achieved remarkable recognition and growth. The company was named #1 Window and Door Company in America for Overall Excellence in the Homeowner Market by Window and Door Magazine—a testament to the team Doug has built. Feldco has been named one of the Chicago Tribune’s Top Places to Work for seven consecutive times (2010, 2011, 2012, 2013, 2014, and subsequent years), and the company continues to earn Top Workplace recognition in 2023.

Doug has been individually recognized by the Daily Herald for Entrepreneurial Excellence, though he graciously shares credit with his entire organization. Feldco generates approximately $61.7 million in annual revenue and has grown to 12 locations across Illinois, Wisconsin, Iowa, and Indiana, including markets in Cedar Rapids, Bettendorf, Des Plaines, Homewood, Grand Rapids, Madison, Menasha, Milwaukee, Peoria, Rockford, South Bend, Springfield, and Wausau.

The company’s recent expansion includes the move to a new corporate headquarters—the “Feldco Hub”—at 6300 N. River Road in Rosemont, Illinois. This nearly 40,000 square foot facility houses Executive Offices, Sales, Marketing, Human Resources, Finance, IT, and the Customer Delight Team. Doug noted the move represents not just a new space but a sign of things to come, stating “we have no plans of slowing down.” Feldco’s commitment to employee retention is reflected in their remarkable tenure statistics—45% of employees have over 11 years of service with the company.
