Michael A. Byerley

Chairman & Chief Executive Officer

Michael Byerley serves as Chairman of the Board and Chief Executive Officer of Global Water Technology, Inc. (GWT). In this role, Michael is responsible for defining and advancing the company’s long-term vision for sustainable growth, service excellence, and innovation. Beyond executive decision-making, he embodies GWT’s values as its principal ambassador and strategic leader within the evolving water technology landscape.

Michael joined GWT in 2009 as a Service and Sales Intern and transitioned to a full-time role in 2011 as an Account and Business Development Manager after completing his studies at Northwestern University. As the son of GWT’s founder, Maria E. Villarreal-Byerley, Michael was the first and only member of the next generation of the Byerley family to join the business. His early focus centered on hands-on technical service, account management, and supporting company growth through new client relationships and talent acquisition.

In recognition of his success stabilizing and growing the business in profitability, revenue, and personnel, Michael was promoted to Vice President in 2013, expanding his responsibilities to include day-to-day oversight of administrative operations, vendor management, sales, and marketing. In 2015, he led GWT through its first acquisition, Midwest Products & Consultants, Inc. (MPC), successfully integrating the business and establishing the foundation for GWT’s disciplined, culture-preserving approach to mergers and acquisitions.

Following Maria’s retirement in 2016, Michael assumed the role of President and became GWT’s sole shareholder, a distinction that continues to afford the company exceptional autonomy, operational flexibility, and the ability to reinvest aggressively for long-term growth. Under his leadership, GWT has evolved from a small regional firm into a national water solutions organization, expanding its service and fulfillment capabilities nationwide, launching new product and service platforms, building a state-of-the-art manufacturing and R&D center, and completing fifteen acquisitions.

Michael attributes his leadership success to time spent working within the business across multiple roles and to the guidance of mentors throughout his career. This experience provided him with deep technical understanding, empathy for the challenges faced by teams across the organization, and a practical perspective on building a modern, scalable water services company. His leadership philosophy emphasizes stewardship, respect for legacy, and the responsibility to grow GWT thoughtfully for the benefit of clients, employees, and future generations.
