At Timberline, we set high quality goals, and then we knock them out of the park. It’s part of who we are. Ask any of our company leaders, staff, and personnel about our current certifications, quality control measures and processes, and they will tell you about our pursuit of excellence.

Our company is AS9100D certified. While not every project needs the precision and quality required for the aerospace industry, it goes into every product we assemble.

Continuous improvement

In today’s competitive market, we understand the need to improve processes on an ongoing basis. Our continuous improvement program, which includes Lean and 5S initiatives, has proven to be very successful, and has resulted in positive impacts on our clients’ — and our own — products and processes.
