Lindsey Taylor
Director of Operations
Lindsey’s career has been rooted in process and people from the very beginning, starting directly on the production floor. With a background in manufacturing engineering, her early career was spent in high‑volume manufacturing and heavy industrial environments, where she supported daily operations, launched production lines from the ground up, and immersed herself in Lean transformations and Kaizen events. This hands‑on, floor‑level experience shaped her understanding of how systems, teams, and execution come together in real time. As her career progressed, Lindsey transitioned off the production floor into program/project management, where she broadened her impact—leveraging her operational foundation to strengthen Lean, Six Sigma, and project management practices and demonstrating how mastering the fundamentals can drive sustainable organizational change.
Lindsey’s hands-on approach began at Rensselaer Polytechnic Institute (RPI), where she earned her degree in Mechanical Engineering. Her curiosity and commitment to continuous learning have created opportunities to deepen her expertise, including earning Six Sigma Black Belt certifications through both ASQ and Caterpillar. To complement her technical background and ensure a well-rounded skill set, Lindsey also holds certifications in Change Management and Situational Leadership.
Outside of work, Lindsey enjoys traveling, spending time with family, cooking, and working out. In one of her first college interviews, she was asked to count how many countries she had traveled to and was told to stop when she reached 32. Experiencing local culture is an important part of how she travels, and when work takes her on the road, she often uses it as an opportunity to try new and local workout classes. While travel has shaped many meaningful experiences, the moments she values most always include her family. They are her biggest supporters and the foundation behind the life and career she is proud to have built.

Ron Barrett
Manufacturing Advisor
Ron Barrett’s path into operations and supply chain consulting was shaped by an unusual combination of engineering training and military service. After earning a degree in Ocean Engineering from the United States Naval Academy, he spent eight years in the Navy as both a Naval Flight Officer and a Civil Engineer Corps officer — experience that instilled a deep appreciation for precision, accountability, and building teams that execute under pressure.
After leaving the Navy, Ron joined GE Energy and spent nearly a decade working across manufacturing, supply chain, and global operations for gas and steam turbine product lines. He had the opportunity to lead a manufacturing startup in Budapest, Hungary — shipping the first unit just ten months after project approval — and later managed capital investment across GE’s global network of plants and service centers. Those years taught him how world-class industrial organizations are built and what separates the ones that consistently deliver from the ones that struggle.
Ron then moved into the offshore marine services industry, where he led global supply chain and information technology for one of the world’s largest vessel operating companies. He implemented ERP systems across more than 20 countries, established shared service centers on two continents, and led sourcing initiatives that generated over $20 million in annualized savings. From there he joined a family-owned Caterpillar dealership, where he held four different senior roles spanning safety, service operations, and sales — and came to genuinely appreciate the unique cultures throughout the state of Louisiana.
Today Ron works as an independent consultant helping industrial and service companies improve how they operate. He brings a straightforward approach: understand how work actually gets done, identify what’s getting in the way, and build practical solutions the organization can own and sustain.
Outside of work, Ron enjoys travel by land, sea or air while sampling the food and culture along the way.
