Dalton, Olmsted & Fuglevand

Our hands on project experience spans conceptual feasibility studies, engineering design, project specifications, bid and award, and construction oversight.

Who we are

DOF is a specialized firm whose mission is to provide hands-on senior level environmental consulting services to industrial, commercial, and municipal clients.

By balancing technical, regulatory, and political demands from inception through completion, we help clients resolve environmental issues with smart, cost-effective solutions.

The principals of the firm are recognized industry experts bringing in-depth understanding of environmental, engineering, geological, hydrogeological, and construction issues to every project.

What we do

DOF provides environmental consulting services focused on stormwater management, soil and groundwater remediation, sediment remediation, and permitting and regulatory negotiations. DOF’s staff of industry experts often take projects from the early site investigations and feasibility studies all the way through to construction management and project closeout.


All of our employees are continuing to work from home and our hours may be a little different than normal, but we continue to be available for communication via calls or web meetings and via regular email, as well as essential fieldwork. We are monitoring local and federal guidance, as well as communicating with regulators and other agencies to evaluate best practices as information unfolds that relates to our work.

As the news of the COVID-19 pandemic continues to unfold, we hope that you and your family stay safe and healthy. Please don’t hesitate to reach out to discuss how DOF may be able to support you navigating environmental engineering and compliance during these challenging times.
