Houston, Texas – LJA Engineering, Inc. (LJA), a nationally recognized, employee-owned engineering and consulting firm, is pleased to announce that Concept Development & Planning, LLC (CD&P), an Austin-based community engagement and strategic communications firm, has joined LJA.

The CD&P team will serve as LJA’s community engagement experts, leading and supporting these efforts across the company.

“This partnership is a natural fit,” said James Ross, PE, LJA President and CEO.  “Our firms have collaborated for nearly a decade, and CD&P’s deep expertise in community engagement strengthens our ability to support clients’ stakeholder engagement needs across the country.”

For CD&P, the transition marks an exciting milestone in the firm’s evolution.

“After nearly 20 years in business, joining LJA allows us to grow, expand, and elevate the services we provide,” said Arin Gray, President of CD&P. “This step also creates new career opportunities for our staff and access to a broader range of projects.”

Pete Peters, Principal of CD&P, added, “LJA’s clients often need strategic communications support, and integrating our team into a larger national platform enhances our ability to deliver consistent quality across a wider footprint.”
