Ivan began his career in the water, wastewater, environmental engineering and design build construction in Wisconsin.  The pull of his native Grand Junction brought him back, where he remained in the civil construction industry as the staff engineer for a company that produced construction materials including concrete pipe and precast products, aggregates, and ready-mix concrete, in addition to managing many land development projects.  Later in his career Ivan managed a large aggregate division of consolidated companies, where he oversaw production, quality control, sales, environmental compliance, and land management.  Over the years, Ivan has designed and/or managed projects across all spectrums of civil engineering, water resources, construction, and materials.

Ivan’s addition to RCC enhances our capabilities in mining engineering, permitting and environmental compliance, water resources, land and construction oversight/management.  Since the early 2000’s he has also been active in volunteering for many notable organizations including United Way, HopeWest, the Grand Junction Economic Partnership, the Twenty First Judicial Nominating Committee, Grand Junction Housing Authority, and the Grand Junction Chamber of Commerce.

We recently had the pleasure of working with River City consultants on a high profile multifaceted million dollar project in Garfield County. The timeline was extremely tight and the work complicated. River City rose to the occasion got the subs in line and finished the project ahead of schedule and under budget. As all project go there were some surprises and changes, River City brought solutions. They are very professional and friendly. I hope we get the opportunity to work with them in the future.
