History

MGT Landscaping first began as Mitch’s Green Thumb Landscaping in 1977 in the State of Illinois. In 1998, MGT expanded from Illinois to Colorado. Mitch Maneval, owner and founder of Mitch’s Green Thumb, turned to Kerry R. Hasegawa to oversee the Colorado branch as Vice President and partner in 2002.

Together, Hasegawa and Maneval have over sixty years of combined experience in landscape and irrigation forming a strong presence in the Colorado market. In June of 2009, Mr. Hasegawa became President and majority owner and finally in the fall of 2012, Mr Hasegawa purchase the remaining shares from Mr Maneval and thus, Mitch’s Green Thumb became MGT Landscaping Inc

Our team is our backbone.
