David Alberto Whitten, President of Thern Electric & Solar, is a California native born in San Francisco.   He began his electrical career at the age of sixteen working as an apprentice for a number of Bay Area contractors on commercial and residential projects.  In 1996, he moved to the Napa area.   His association with Thern Electric & Solar began in 2000, when the company was owned by Paul Kern.   The company name at that time was The Electric Company.

David continued his training and education and in 2003 became a California Certified General Electrician.   Also in 2003, The Electric Company incorporated and, not surprisingly, that name was already being used, so the company took the corporate name of Thern Electric INC.   In 2006, David became an owner of the company.   In 2009, when the company began its solar work, the dba name Thern Electric & Solar was added.

Dave keeps abreast of the new electrical technologies and green building innovations by attending seminars and continuing education courses.

David is married to Heather and is the father of two children, David Bay, age nine, and Vivian Diane, age three.   He is active in his son's youth baseball league assisting with coaching and field maintenance.
