Sean Keller recently joined APsystems as our Business Development Manager for the Northeast, bringing a strong background in construction and a passion for helping partners succeed.

What drew Sean to the solar industry is the opportunity to be part of something bigger—helping create a better future for the planet and for future generations. While he’s new to solar, he’s committed to learning everything he can about the industry and APsystems’ products so he can provide the best possible support to customers across the Northeast.

Sean is excited to combine the skills he’s built throughout his career with the hands-on training at APsystems to help installers and partners grow their businesses with confidence.

Outside of work, you’ll likely find Sean on the slopes whenever winter cooperates or spending quality time with his three-year-old daughter.

After eight years in solar—and another eight away—Isaac is back in the industry and excited to be part of the rapid innovation happening across energy technology.

For Isaac, what makes solar exciting is how constantly it evolves. From new products and applications to the growing push toward energy independence, he’s passionate about helping customers navigate the changes and build long-term partnerships that last.

Covering Arizona, Nevada, California, Colorado, New Mexico, Utah, and the Mountain West, Isaac is focused on earning trust by being the kind of partner he’d want to work with himself—someone who listens, works hard, and helps businesses succeed together.

Outside of work, you’ll probably find him paragliding, skiing, or white water rafting. He’s flown in 15 countries, including a memorable flight over a castle in Slovenia before landing in Italy.
