He started installing irrigation systems after obtaining a California contractors license in 1988. He branched out into landscape renovations and added low voltage outdoor lighting systems in 1989 after attending a seminar led by Bill Locklin.

The maintenance division was sold to two former employees in 1996.

Gregg traces his start in horticulture to 1974, and the Ornamental Horticulture program at the San Jose Regional Vocational Center. He earned an award for outstanding achievement in O.H. in 1975 while in high school.

In 1976, Gregg entered an apprentice program at the Saratoga Community Garden where he worked and studied organic gardening for 2 years.

He helped found Mayfair Community Garden in San Jose in 1978, and later headed a small crew who worked to preserve and restore the (sadly) short-lived Nelson Gardens in Saratoga.

Gregg studied horticulture at Foothill College in Los Altos Hills, and Cabrillo College in Aptos.

He is a past president and education chairman of the San Jose Landscape Gardeners Association, a former delegate to the Professional Gardeners Federation Of Northern California, and a former member of the advisory board for Foothill College's Ornamental Horticulture program.

Gregg would like to take a moment to thank a long list of friends, influences and occasional mentors, some living and some passed on, including (and in no particular order):  Lester Catanese, Roy Barsotti, Ray Chew, Frank Schiavo, Brian Gage, Louis Saso, John Dotter, Perley Payne, Dan McGrath, Tanso Ishihara, Charles Griffin, George Masamori, Chuck Konigsberg, Bob Will, Richard Merrill, Glenn Matsumoto, Bill Locklin, Irv Harding, Fred Sugimoto and Geri Roe.

Gregg thanks his friends for sharing their knowledge, their  skills and their support.
