Since 1977, the principal civil engineers of
Ketterling, Butherus & Norton Engineers have
been providing engineering services in
Greeley and Northern Colorado.

In July of 1995, these principles joined forces
and formed KBN Engineers. Our reputation is
built on integrity, skill and creativity,
strengthening our communities, performing
exciting work, and serving our clients. This
philosophy, coupled with the energy and
passion of our professional staff, has
produced an engineering firm who is
committed to collaborative project success
and a respected engineering leader in the
Northern Colorado Region.
