Our Values





Core Values Commitment
Executive Leadership
- “At REI Utility Services, our core values are more than words — they are the compass that guides every decision, relationship, and project. Founded by Mike Mayo and built on a legacy of Reliability, Ethics, Integrity, Unity, and Service, these principles are the heartbeat of our company.”
- “They shape how we serve our Big C — our utility clients and partners — and our little c — our team members who make it all possible. We believe that without a clear set of shared values, any organization can lose its way. That’s why, from the beginning, our leadership has been committed to living these values daily, ensuring consistency, trust, and excellence in everything we do.”
