Since being hired to work on the survey crews after his graduation from Purdue University in 1978, Mike has spent over 35 years with Kohli and Kaliher. In 2002, he became a principal with the firm, and is currently the company secretary. He also serves as the Chief Surveyor for the company and is the main contact person for survey proposals. He specializes in the preparation of legal descriptions and drawings for property surveys, and for bridge and highway projects—including the U.S. 30 relocation east of Beaverdam, the U.S. 24 Bypass Improvement at Defiance, the Eastown Road Improvement in Lima, the Ottawa River Bikeway Project in Lima, the Vine Street Railroad Grade Separation Project in Lima, and the Shawnee Road Roundabout Project in Lima. He is also responsible for the preparation of all right-of-way plan sheets that are required for those types of projects.

Through the years, Mike has also had significant experience with topographic and title insurance (ALTA) surveys, engineering design, and site planning—especially for industrial and commercial properties. The Eastgate Shopping Center east of Lima is a good example of an ongoing development project where Mike has been involved with several aspects of surveying and engineering work. He is also responsible for the preparation of subdivision plats, annexation plats, and street dedication or vacation plats.

Other Interests

Mike’s passion for maps and history has served well in his research work on roads and highways—both as a professional surveyor and as an amateur historian. He is regarded as one of the leading authorities on the history of the Lincoln Highway in Ohio, proclaimed in 1913 as the nation’s first transcontinental automobile route. He has prepared a unique compilation of his research, photographs, and original drawings in a self-published book entitled A History and Road Guide of the Lincoln Highway in Ohio.

His similar fascination with railroads has inspired Mike to develop a continuing education program entitled “I’ve Been Learning on the Railroad,” which has been presented on several occasions at conferences of the Professional Land Surveyors of Ohio. The first presentation of this program was at the PLSO Fall Conference in Lima in October 2003, where Mike also served as the program chairman. The entire event was hosted by the Treaty Lands Chapter of PLSO, in which Mike has been active as either president or secretary for many years. He continues to create other continuing education programs not just for his own professional development, but for the professional development of other Ohio surveyors.
