Ryan Nestor – Managing Principal, since 1997

Food. Water. Shelter. At its core, Ryan’s practice explores designs where these three basics of survival coexist in their most elevated and celebratory states – the places where people assemble en masse to eat, drink, and be entertained. Ryan is the co-founder of Barker Nestor Architecture + Design – a leading hospitality design firm based in Chicago with a 20 year portfolio of hundreds of highly-regarded restaurant, bar, hotel, and entertainment design projects spanning the United States.

Ryan orchestrates collaborations with his clients, architects, engineers, interior designers, graphic designers, and brand designers in custom dynamic design processes for market analysis, site selection, real estate/regulatory negotiation, conceptual design, and ultimately, project design, implementation, and construction. Challenging his clients to distill their business concepts to their essence and eschew convention to enhance their market differentiation, his projects advance the traditional notions of ‘assembly’ and ‘congregation’ by elevating the basic human necessities of food, water, and shelter from the merely necessary to the celebratory and profoundly experiential.

Awarded a baccalaureate of architecture and also a baccalaureate of science in environmental design from Ball State University, Ryan later diversified his education at the Chicago-Kent College of Law at the Illinois Institute of Technology. There, he was a member of both the Law Review and the nationally-recognized Trial Advocacy Team competing in national tournaments. Ryan has served as a guest jury critic for the interior design program at Columbia College in Chicago and the College of Architecture at the Illinois Institute of Technology. He has also guest lectured about hospitality design at Roosevelt University’s hospitality management program in Chicago.

Since 2015, Ryan has taught visiting architectural students from abroad and lectured at Chicago’s revered alternative design school – Archeworks. ( There, Ryan extends Archework’s mission of using design as an agent of change in the public interest by driving dialogue in the Chicago Complex program. Currently, Ryan also sits on the Archeworks Board of Directors tasked with shaping the school’s vision of social relevance through its next chapter.
