Paul Drake and Dale Van Wyk founded MechSigma Consulting with a mission of designing mechanical products that meet quality goals without compromising manufacturability or performance.

Our expertise includes 35 combined years of experience as mechanical design engineers and 20 combined years of experience in mechanical design for Six Sigma. We have successfully deployed Six Sigma mechanical processes at Raytheon Systems Company (formerly Texas Instruments Defense Systems and Hughes Missile Systems) where we co-managed the Mechanical Tolerancing and Performance Sigma Center for Excellence.

Our qualifications include:
