RATIO Design (RATIO), an Indianapolis-based international design firm, has expanded its expertise in the hospitality, mixed-use and entertainment district sectors with the addition of architects Clay Markham and Angie Wallin.
Most recently with CallisonRTKL, Markham and Wallin have a range of rich design experiences in the southeastern US, Chicago and internationally.
Markham was a Managing Principal and the Hospitality Practice Area Leader, and Wallin was the Vice President of Business Development, leading national efforts for CallisonRTKL’s North America Commercial Practice.
Both are stepping into leadership roles as Principals and senior members of RATIO’s Hospitality and Mixed-Use practices. They will work with our existing leaders to pursue new opportunities and design transformative spaces and guest experiences.
Markham brings over 40 years of industry experience in hospitality design and delivery around the globe. His successful management approach across architecture, interior design, and construction management has resulted in award-winning projects for clients and brands such as Hyatt, Marriott, IHG and MGM Mirage. The Maike Centre and Grand Hyatt Hotel in Xi’an, China, was given the Award of Excellence in 2020 by the CTBUH (Council on Tall Buildings and Urban Habitat).
Wallin, located in Chicago, has an extensive background in real estate, architecture, and design, in addition to her tenure in interior design. This has greatly influenced her approach and track record for developing high-impact partnerships and new opportunities for client success.
She will lead local and nationwide business development efforts for hospitality, mixed-use, multifamily, and entertainment district projects in her new role. She specializes in helping developers, design firms, and clients form unique partnerships to enhance their cities.
