Alley Tree and Landscape Inc. was established in 2016 when Dean and Karissa Alley made the decision to move back to Sonora to raise their family.  Dean grew up from a young age working for his father's tree business before attending California State University  Stanislaus and graduating with a degree in Agricultural Studies and a concentration in Landscape Design. While working as a landscape designer and construction manager of commercial landscapes in the northern bay area region, Dean obtained his arborist certification becoming a second generation ISA Certified Arborist in Tuolumne County. 

His wife Karissa Alley is a labor and delivery nurse as well as the CFO of Alley Tree and Landscape Inc. and the mother of three children, Adelynn, Hudson, and Bristol.
