About JDH Engineering, Inc.

JDH Engineering was founded in 1981 by Robert Johnson as a sole practitioner. Ralph DenHartigh (1985) and Larry Hulst (1989) joined Robert as partners and the three of them led the company together for 23 years.

In 2012, JDH Engineering became an employee owned company comprised of 7 shareholders, with Ralph DenHartigh remaining as President . This group of individuals has worked together for a decade, building the teamwork and trust needed to effectively collaborate on significant projects. 

Our team of talented employees is key to our success.  Our engineers have a combined 150+ years of professional experience and our full-time staff have been with JDH for an average of 11 years each!
