Our History

Robert J. Jonker, P.S. established the firm in 1981 and has been surveying since 1963. Randy followed in his father’s footsteps and started surveying in 1991. The bulk of our work is done in and around the following counties: Allegan, Barry, Ionia, Kent, Montcalm, and Ottawa. We work with a variety of people including realtors, lawyers, contractors, zoning officials, civil engineering companies and especially land and home owners. Cellular tower certifications are done on a semi statewide basis covering the western lower peninsula.
