Who We Are?

 

Founded in 2016 by Dean and Karissa Alley, Alley Tree and Landscape, Inc. was created to serve the Sonora community while raising their family. Dean, a second-generation ISA Certified Arborist, grew up working in his father’s tree business. He earned a degree in Agricultural Studies and Landscape Design from California State University, Stanislaus, and later worked as a landscape designer and construction manager in the Northern Bay Area.

Karissa, a labor and delivery nurse, is the CFO of the company and manages the financial side while raising their three children: Adelynn, Hudson, and Bristol.

Together, they bring their expertise and passion for quality service to every tree and landscaping project, ensuring customer satisfaction with every job.
