We have been working with Keller Engineers of New Jersey and have found the firm to exhibit the highest quality of professional engineering in construction inspection/management. Keller has been exceptionally responsive, supportive, and versatile in all aspects of engineering, especially over the duration of construction inspection support by Keller on our recent New Jersey Turnpike projects. The staff is well trained and educated in the forefront of technology. Keller Engineers take both responsibility and pride in satisfying their customers of which we are grateful to be included.
