Pardon our dust — we’re re- engineering our website!

Our website is getting a new look...

During the renovation, we’re keeping the site live, so you may notice a few glitches, rough edges, or pages in progress. Consider it a working prototype.

Professional Engineers Day Proclaimed in South Dakota

South Dakota is recognizing the vital role engineers play in shaping our communities and improving daily life.

Governor Larry Rhoden has officially proclaimed Wednesday, August 6, 2025, as Professional Engineers Day in South Dakota, honoring the dedication, expertise, and public service of professional engineers across the state.

Professional engineers design and maintain the infrastructure we rely on every day — from roads, bridges, and water systems to buildings, energy systems, and emerging technologies. This proclamation highlights the importance of engineering in protecting public safety, supporting economic growth, and advancing innovation throughout South Dakota.

In addition to the statewide proclamation, several communities joined in recognizing Professional Engineers Day. We extend our sincere thanks to the following mayors for issuing local proclamations:

  • Oep Niemeyer, Mayor of Brookings

  • Garry Symens, Mayor of Dell Rapids

  • Gloria Hanson, Mayor of Fort Pierre

  • Steve Harding, Mayor of Pierre

  • Jason Salamun, Mayor of Rapid City

  • Paul TenHaken, Mayor of Sioux Falls

The South Dakota Engineering Society appreciates the leadership shown at both the state and local levels in recognizing the contributions of professional engineers. We are proud to celebrate the engineers who serve South Dakota’s communities with skill, integrity, and commitment.

Happy Professional Engineers Day to all who help build and sustain our state.
