Peter Holtgreive introduced our sign company to Lean Manufacturing two years ago. We were moving from a 8,700sqft to a 20,000sqft facility. Peter helped set up the shop, the offices and then how to work both in the most efficient way possible. We then moved from the Basic Principles of Lean as it applies to mass production, to learn about Lean for the Job Shop (custom manufacturing) As part of our Continuous Improvement Program, Peter helps keep us on target and accountable. We highly recommend Peter for his knowledge, teaching skills, positivity and good humor! John Dobie, President BSC Signs, Broomfield, CO
