ADG has promoted architect Alison Heasley to Project Manager. Heasley’s most notable accomplishment with the firm has been her work as project architect on the historic First National Center renovation project in downtown Oklahoma City. She worked closely with owners, contractors and a multitude of specialty consultants to carry out renovation designs for every inch of the 33-story building. This challenging project required creative solutions and extreme attention to detail in order to retain as many of the building’s original features as possible while providing modern amenities for hotel patrons, residents, retail customers and parking.   

“Alison’s greatest asset is her comprehensive understanding of her projects and determination to achieve a project’s core goals. She balances budget, constructability and a solid design sense to give our clients genuine value in their completed work.” said firm partner, JC Witcher.


Heasley is a registered architect and has been with ADG for nearly four years. She has several years of experience coordinating other large-scale projects. Her experience includes multifamily housing, hospitality and HUD-financed projects. She has served as project architect on Oklahoma City Argon Apartments at Chisholm Creek, Terra Apartments in Norman, and recently renovations for NewView in Oklahoma City.  She holds a Master of Architecture and Bachelor of Science in Architecture from Ball State University.  She is a member of the American Institute of Architects and is also a certified architect through the National Council of Architectural Registration Boards.

ADG is committed to providing quality architectural, engineering, interior design, planning and program management services for owners, building users and communities throughout Oklahoma and in other parts of the United States. The firm employs nearly 70 employees and has called Oklahoma City its home since starting business in 1975.
