Devyn Pizzo

Founder & CEOAscend Education GroupLinkedIn ↗

Electrical design engineer and founder of Ascend Education Group and Ascension Renewables LLC, with 7+ years in the industry and 250+ distributed energy projects across nine states.

Her work spans feasibility, electrical design, project engineering and management, procurement, product development, installation, and operations.

Working across the whole project lifecycle showed her how decisions in one discipline create consequences in another. That became the foundation for Ascend.

Now her focus is the work she cares about most: educating the next generation of engineers, technicians, and leaders who will build and run tomorrow's energy systems.
