About Us


Ron Nelson
President and CEO founded California Design in 1990 with a expert employee team to serve the needs of the window and door replacement market, with a manufacturing facility in Riverside California providing oak, mahogany and douglas fir windows and doors through out Southern California. In 1995 per the market trends Mr. Nelson selected vendors meeting the companies standards for performance and good customer relations to supply maintenance free energy efficient Green technology products direct to California Design so they could operate as wholesale distributor and installation company. Only the best companies remain as suppliers thru the company.  California Design pioneered this business direct approach for consumer satisfaction. Many other companies try this approach, however the other companies do not have the expertise to manage their own installation crews and employees which is why checking a license for the number of years in business is so important. For over 26 years in this industry the company is proud of having a long term license from CSLB 602325 which is a unique accomplishment. If a license is above 850000 it has not been around very long.

Our Mission Statement ” The customer is the means of our existence” exhibits the focus of satisfaction and the great number of referral customers continuing to grow the company over the years.

Mr. Nelson served 28 years prior to founding the company as a executive of a Fortune 100 appliance manufacturing company, Magic Chef/Maytag managing various divisions of the corporation across the United States, and Europe. In his capacity he developed the company builder division which gave great insight into the needs of the remodeling and home improvement industry.
Through Mr. Nelsons guidance the firm has installed and replaced over 250,000 doors and windows along with various associated new products in the awning, outdoor cooking industry grills and islands plus remodeling homes to todays updated standards with a broad selection of designs for todays consumer.
The company has always operated its own, one of the first in the industry locally, installation crews for the creation of final results which are company controlled and directed producing superior results.
Using the same business approach which serves the consumer so well, the company over the last year has expanded into the Air Conditioning/Heating replacement with expert leadership of a industry veteran, Mr. Paul Rustigian and the offering of the top Amana Brand, plus other selected brands.
Mr. Nelson has appointed a outstanding team led by installation manager, Larry Lewis, and installation supervisor Steve Clements. They have been employees of the company for over 10 years insuring the projects are correct and on time.
