  • I would recommend this business

I have worked with the surveyors and engineers at SSW Engineers Inc for more than five years. Each of the projects that SSW Engineers has undertaken both for me personally and for my business have been performed on time, within budget and have been performed to the highest standards. Mike Dahrens, PLS, the lead surveyor has done general surveying, forensic surveying and has provided expert testimony in several extremely complex lawsuits. I credit our success in these matters in major part to Mike's skill, breadth of experience and effectiveness in his representation of his clients. I offer my highest recommendation of Mike Dahrens and the staff at SSW Engineers Inc and would be pleased to discuss my recommendation personally with prospective clients.
