Who We Are:
Owners: Andrew Simpson
& Linda Quillen
Quillen Enterprises Inc, owned by Andrew Simpson, began business operations as Midwest Sprinkler Co. in 1974 and is now an Award Winning  landscape company.  
Specializing in a unique irrigation installation process, Simpson offers “trenchless” pipe installations, especially desirable in established lawns.     
Consistent quality and ethics are the hallmarks of Quillen Enterprises. Mr. Simpson has won over twentyone awards 1998-2010 including three “Best in the State of California” sponsored by the California Landscape Contractor’s Association. This is especially meaningful since this is a peer judging landscaping industry competition throughout the state of California.
He has established himself as an innovative landscape artist.  His creative and unique ideas are interpreted through rock, plants and pebbles as he brings the beauty of Hawaii to some Sacramento clients and the serenity of waterscapes for others.  His individually crafted commercial copper waterfalls have created a demand for his talents.   
 “My Father owned a landscape nursery when I was born, the acreage of trees, roses and greenhouses were my playground as I grew up.  Dad began landscaping in the 1930’s and used a team of horses to grade and prepare lawns from seed.  My grandfather was a “truck farmer” at the turn of the century.  My oldest brother owns a large distributorship of landscape and irrigation products.  My second oldest brother owns an irrigation installation company, much like mine.  I guess you could say I was born into this life, and I love it.” Andrew Simpson
In 1991 Mr. Simpson moved to California from Colorado, married Linda Quillen and began partners in life and business with Linda as Quillen Enterprises.  They hold state landscape contractor’s license number C-27 / 844055 and are current members of the California Landscape Contractor’s Association.  Mr. Simpson recently served on CLCA's state board of directors.  In 2006, Mr. Simpson was elected president of CLCA, Sacramento Chapter.  Mr. Simpson has been certified by the American Society of Irrigation Consultants, as both designer and auditor.  His company has installed over 1,600 residential sprinkler systems, and over eight hundred complete landscapes.  His largest completed project is a state-of-the-art irrigation system for an Arnold Palmer designed golf course in Philadelphia, PA.
