Founder + Board Treasurer

Brandon Little, elemental energy

Brandon’s interest in renewable energy began during his college days—while studying pre-med with the goal of becoming a surgeon, he ran a side business focused on investing stock in the sustainable energy industry. This belief transitioned into a full-fledged interest when he realized that, solar, rather than medicine, was the dominating force for change that he wanted to be a part of. With that, he returned to the Oregon Institute of Technology to earn a degree in Renewable Energy Engineering. After working at Elemental Energy for several years and participating in multiple international solar PV installations, Brandon joined John Grieser in forming Twende Solar.
