Our Story

D.P. Nicoli, Inc. was founded in 1982 by David P. Nicoli. David started DPN primarily as a piling distributor and plate rental company. He then added shoring and slide rail products, which would establish D.P. Nicoli as the only one-stop resource for the shoring needs of the heavy construction industry in the United States.

Now, 30+ years later, D.P. Nicoli has a strong presence in the entire Western United States.
