Joe Koch Jr., President | Deer Park Construction

I have worked with DIFFCO on several projects for Union Pacific Railroad.  I have been very pleased with their responsiveness and their quality of work.  We have worked together to get through several difficult scheduling problems.

Dee Gibson, P.E. | Pacific West, LLC

Rosenberger Construction appreciates the relationship we have developed with DIFFCO over the past few years.  They are aggressive, competitive, and competent in the work they perform and have a truly customer focused staff.  We gladly look forward to pursuing future work with DIFFCO.

DIFFCO constructed a tanker truck parking lot, both cast concrete slab and stabilized crushed concrete parking surface.  The job was done efficiently, professionally and safely.  The site supervision conducted themselves professionally and I would not hesitate to bring them in for another civil construction project.  The project was bid and done for the cost quoted.  DIFFCO has stood by their work and their word.
