We are very proud of our new office addition. Keller Engineers provided excellent guidance and support throughout our building project, which included key elements such as: structural recommendations, land development, environmental planning, and a beautiful rain garden. We knew we could trust the expertise of Adam Long, RLA and Brian Smith, PE in helping us create a practical and beautiful building and streetscape that enhances our neighborhood and the community.
