About Jeremy & Tara

For 25 years, Jeremy has been working with underground municipal utilities in and around the Des Moines area. After getting his start in the construction business as an operator/laborer with Horsfield Construction in Epworth, Iowa, he went on to work for Dave Schmidt Construction in Cedar Falls while attending Upper Iowa University.

After attending Iowa State University, Jeremy worked for KRI Company in 1998, where he trained in project management and acted as company superintendent. In 2007, he proudly established J & K Contracting.

Jeremy and his lovely wife, Tara, are united as owners in maintaining the family culture at J&K. They both are involved deeply in all aspects of the organization. They both believe in the core values that are a big part of the entire J&K Team, and promote these values throughout the organization. Family is where it all starts and with their five children there is no time to miss out on family functions. Together they travel from one meeting to another and follow it up with chasing a daughter to a dance competition or softball game and then hit their sons baseball game. They are the parents who not only do what it takes to “Be There” for their own children, but also for the “J&K Family”. Jeremy and Tara always strive for the “Greater Good of the Company” along with their “Family” they are one in the same for the Feldmann’s.

Jeremy and Tara are active NUCA members where Jeremy is an active board member and past President of NUCA. They have been active members and have held these positions for the past 13 years. Jeremy and Tara are also active in the Construction Financial Management Association and National Federation of Independent Business Owners. The owners here at J&K believe in the education and promote the water sewer industry with safety of its team first.
