About my education and beginning of my career

UC Berkeley2

Career3

• Fall 2005 – Spring 2007

• Still deciding what to major in: Architecture or Engineering

• Much cheaper alternative than going straight to university

Chabot Community College

1

• Fall 2007 – Fall 2009

• Graduated with B.S. in Civil Engineering

• Internship opened many opportunities

• Led to full time position at City of Palo Alto

• Began a career at the Pacific Gas & Electric Company

Transferred to UC Berkeley

Took two and a half years averaging 15 credits per semester

Chose to specialize in structural engineering

Course work at Berkeley is much tougher than Chabot-Study hard-Develop good relationships-Take advantage of available resources

Internships

Interned for the City of Palo Alto while at Chabot

• AutoCAD experience was invaluable (ENGR 22)

• Performed mapping and basic surveying for utilities

• Continued working part time which led to a full time position

after graduation

PG&E offers internships

• 147 college interns during Summer 2013

• Mechanical, Civil and Electrical from 60 different colleges

• ‘Felt part of a team doing important work that’s helping make

PG&E the safest gas utility in the country.’
