Nolan graduated with an AAS in Computer Aided Drafting from Mesa State College (now CMU) in 2008 and has 17+ years of Civil design experience in both public and private sectors, the last 14 years being at RCC. During that time he has worked on hundreds of projects across the Grand Valley area and beyond, developing unparalleled technical expertise and acquiring extensive design experience. With a superb attention to detail, relentless drive for perfection, and determined work ethic, Nolan brings consistency and reliability to River City Consultants. He will be primarily focused on production coordination, behind the scenes support, and day-to-day taking care of (the) business.
Originally hailing from Minnesota, Nolan has called Grand Junction home since 1998. Outside of work he enjoys building computers, embarking on adventures in Azeroth, and on the odd chance he leaves the house, may be spotted at the ice rink skating with his daughter or at the park collecting Pokémon.

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.
