Cornerstone One to host open house at new Oshkosh facility

December 1, 2025

OSHKOSH – CornerStone One will celebrate the grand opening of its new Oshkosh location  (3200 N. Main St.) with an open house and ribbon-cutting ceremony at 10 a.m., Dec. 12.

In conjunction with the celebration, Founder Steve Adkins said CornerStone One will raise funds for the Oshkosh Area Community Pantry to help combat food insecurity – matching all donations made at the event to support the new community.

Adkins said the Oshkosh expansion adds in-house manufacturing capabilities to CornerStone One’s HVAC Mechanical Division, allowing the team to provide comprehensive mechanical services, including design/build installations, equipment replacements and routine, emergency, predictive and preventive maintenance. 

“The excitement around this expansion has been growing,” Adkins said.
