Jonathan Arena is a management educator, published author, and executive with more than 25 years of experience leading teams across technology, operations, and professional services environments.

Over the course of his career, Jonathan has served in leadership roles including CIO, CISO, and VP of Operations, working with growing organizations and global teams. While his background is rooted in technology, one lesson became clear early on: success is never driven by systems or processes alone. Everything ultimately comes back to people.

Jonathan focuses on practical management skills that help supervisors and emerging leaders build trust, create clarity, and deliver results through their teams. His approach emphasizes real-world application over theory, drawing from firsthand experience managing change, developing leaders, and navigating the challenges managers face every day.

He is the founder of ManagerU, a practical management training platform designed to help new and emerging managers build the confidence, tools, and judgment needed to lead effectively.
