What REES Associates does
REES Associates is an employee-owned (ESOP) architecture, planning, and interior design firm founded in 1975 by Frank Rees, Jr. in Oklahoma City. The firm delivers professional design services — full architecture, interior design, and strategic planning — across four primary verticals: healthcare, corporate/commercial, senior living, and multifamily, with additional government, civic, and nonprofit work. Specialized technical capabilities include complex healthcare facility design such as surgical units, NICUs, women's health centers, cancer care environments, pediatric rehabilitation, and behavioral health facilities, alongside corporate headquarters, workplace interiors, multifamily residential developments, and federal/municipal buildings. A LEED Silver certification on a 440,000 sq ft Fortune 500 technology headquarters reflects competence in sustainable large-scale workplace design.
The firm operates from three offices — Oklahoma City (headquarters at REES Plaza on Lake Hefner), Dallas, and The Woodlands in the Houston area (opened 2022) — serving clients across Oklahoma, Texas, and select work in Mexico and Alabama. Revenue is generated through project-based professional services fees that vary with scope, complexity, and scale; engagements are acquired via direct consultative sales, repeat enterprise clients, referrals, and industry reputation rather than productized channels. The client roster spans healthcare systems (Mercy, Stillwater Medical, Chickasas Nation Medical Center, Bethany Children's Health Center), government (FBI, City of Edmond), large corporations (Fortune 500 technology firm, Goosehead Insurance, Cox Communications, N5B Capital), real estate developers (Legacy Partners), and nonprofits (ReMerge, Sunbeam Family Services, Oklahoma Center for Nonprofits).
Governance is provided by an external board and an ESOP structure in which full-time employees begin receiving contributions after one year (100% vesting after five years), with Senior Associate-level employees becoming direct shareholders with voting rights and equity returns. CEO Allan Parr led a generational transition away from the founder, and the firm marked its 50th anniversary in 2025. REES maintains active industry presence through IIDA, AIA Central Oklahoma, ENR, and Oklahoma Interior Design Coalition awards, as well as community involvement including the Allied Arts Campaign for the Arts, United Way, and youth architecture education programs.
