Senior Vice Presidents

Promoted in March 2025, three long-serving Maccor veterans now lead the company's operations, manufacturing, and global commercial functions.

What Drives the Team

🇺🇸

Made in America

Every Maccor system is designed, engineered, and manufactured in Tulsa, Oklahoma. That is not a marketing position — it is how Andy MacKay founded the company and how it has always operated.

🔬

Engineering First

The leadership team's backgrounds span physics, electrical engineering, battery manufacturing, and quality assurance. Technical depth is the basis of every product and support decision Maccor makes.

🤝

Long-Term Relationships

The three SVPs have a combined 68 years at Maccor. Maccor's representatives average over ten years with the company. Long tenure is a deliberate principle, not a coincidence.

🌍

Global Reach, Local Support

Systems operating in over 60 countries, supported directly from Tulsa in the Americas and through experienced regional partners worldwide — each with deep hands-on Maccor product knowledge.
