Founded in 1962, R.K. Johnson & Associates has been providing engineering and land surveying services to Northern Illinois for nearly 50 years.
The experience and knowledge gained in these decades of operation was further enhanced in 2008 when R.K. Johnson purchased Carroll Engineering & Associates.
By acquiring Carroll Engineering in its entirety, R.K. Johnson has successfully integrated two successful, independent companies to create a single firm with over 60 years of experience in a wide variety of civil engineering disciplines.
