Austin, TX, June 6, 2016 - Martin Instrument, the premier, authorized Trimble dealer of survey and construction equipment in Texas, has announced Bobby Hempfling and Mike Minick as new owners.

Bobby Hempfling, the new President, has been part of the Martin Instrument team for 11 years, managing the sales department. During that time he has helped grow the revenues of the company more than three fold with his leadership. He will be taking charge of the overall management and strategic direction of the company. Co-owner and new Vice-President Mike Minick, who has been with the company over 12 years, will be in charge of seeking out new business opportunities and managing the company’s new technology expansion into UAV drones and 3D laser scanning.

“We have been so lucky to have had the opportunity to work for Marty and Gina  over the years, and in the process have learned a lot about running a small business effectively.  Mike and I plan on capitalizing on our past successes and growing the business further with our ability to listen to customers and provide them with the solutions they need,” said Hempfling.
