Department Spotlight: Engineering

Medina EC employees work behind the scenes and in the community

Medina Electric Cooperative’s engineering department, composed of six divisions, does a lot to maintain the reliability and plan for system growth for the cooperative. In honor of National Engineer’s Week, recognized February 19–23, we’d like to feature our engineering department which is adept at handling the day-to-day challenges in the engineering world, including high levels of math, science and technology literacy in the utility industry.


Keith Calle is the chief engineering division officer who oversees all six divisions of the engineering department. He brought his wide variety of electrical engineering experience to Medina EC in early 2019.


Paula Pohler and Rachel Solis, both GIS technicians, help maintain a connected model of co-op assets. Mapping equipment and technology allows us to store, analyze and manage data geographically.

System Operations & Outage Management

Allen Boehme, Deborah DeLeon, Chris Muennink and Susie Zerr have filled various other roles at the co-op before joining our system operations team. Their previous roles and knowledge make them experts to find ways to reduce the frequency and duration of outages experienced by members and improve personnel safety.

Smart Grid

Our infrastructure has been undergoing an upgrade the past few years, a large part of that being done by Philip Crow, Marty DeLeon, Monte Tschirhart and Matthew Stinson. This team manages the meters and communication technology to support more reliable reads of our meters.

Line Design

The line design team is made up of Jeff Hier, Fidel Aranda, Roger Besares, Ben Falcon, Lindsey Muennink, Isaac Solis and Janet French. They are responsible for designing new service and line extension projects, and creating cost estimates and material lists.

Engineering Equipment & Electricians

Joel Gonzales, Ricky Cerna, Eduardo Chapa, Marcos Munoz, Fernando Rangel, Darrell Ritchie and Roland Elizondo make up this team. They manage much of the equipment that goes into a reliable and safe electric infrastructure.

Business Development

Katie Haby, Brian Bell and Michael Harkins work to build relationships with key accounts and new prospective businesses in our service area. They also oversee the member rebate program and our solar and generator installations.
