About

Our Mission Statement

BKL provides inspired and purposeful designs to enhance and connect communities.

Our Story

Founded in 1946, BKL has proudly served Oklahoma communities for nearly eight decades. What began with a focus on detention and justice projects has grown into a full-service architecture and engineering firm trusted by municipalities, counties, and public agencies across the region. Our story is built on authentic relationships and a spirit of moxie—never shying away from complex challenges. That drive, paired with our reputation for being reliable partners, has led to long-standing collaborations with city and county governments.

Today, with the leadership of principals Jenni Hammock, Ryan Mahaffey, Stacy Loeffler, and Jayde Dzierba, our portfolio spans civic buildings, public safety facilities, infrastructure, water/wastewater, and transportation improvements—all designed to strengthen communities for generations.

Our Expertise

 BKL offers in-house architecture, civil engineering, structural engineering, and construction administration—a multidisciplinary approach that fosters collaboration and resourceful problem-solving.

We are known for being agile, adapting quickly to shifting project needs while maintaining high standards of design and delivery. Whether modernizing a courthouse, upgrading a wastewater treatment plant, or designing a gathering space, our team provides innovative, cost-effective solutions that consistently exceed expectations.

Our Purpose

At BKL, design is about more than buildings and infrastructure— it’s about people. Guided by our commitment to community, we engage stakeholders early and often to ensure every project reflects local values and long-term goals.

Our size allows us to bring the depth of experience found at larger firms while remaining nimble, responsive, and personally invested in every project. This authentic approach, backed by our reliability, helps ensure lasting value for our clients and the people they serve.

Our Core Values

moxie • agile • authentic • reliable • resourceful • community

Our Team

BKL is a team of problem solvers and innovators who thrive on going above and beyond. We offer our clients something greater than just design – we help them to achieve their goals.
