Jon Ledsworth
Jon left a successful 25-year career in sales and project management in the industrial custom printing industry. He was in search of something more dynamic and inspiring within the communities he served.
In the Spring of 2019, Chart House Energy offered Jon an opportunity to lead the community impact initiatives of the company. He quickly realized the degree of positive influence that solar development has in communities, whether the projects are municipal, nonprofit, industrial, commercial, or residential. His focus at Chart House Energy has been to strategically pursue solar developments that will leave a community stimulated long after the solar installation is complete; a community that continues to benefit far beyond the clean and renewable solar energy itself.
