This year, American Tree Experts proudly celebrates 75 years of family-owned and operated arboriculture services in southeast Wisconsin.
Since its founding by the late Chester Ziemienski in 1950, the company has remained committed to enhancing the beauty, health, and prosperity of the region’s trees and landscapes. With a team of certified arborists, American Tree Experts serves thousands of homeowners, condo associations, rental property managers, local businesses, and institutions, ensuring that urban forests continue to thrive for generations to come.
Today, the company is led by Chester’s son, Jesse, who has served as president since 1989, and his grandson, Dean, who has been vice-president since 2007. Despite the many changes in the tree care industry, the core values of dedication, integrity, and commitment to responsible arboriculture remain at the heart of our company.
Your continued support has been instrumental in our growth and success. As we mark this milestone, we extend our heartfelt thanks to our customers, both past and present, and our home community of New Berlin, for your trust and loyalty.
