John Portz

Technical Sales Executive / Manufacturing Engineering Technician

My name is John Portz and I was born and raised in Dubuque, IA.  After high school I attended some college and started my career in a tool & die apprenticeship program.  I spent about seven years working as a tool room machinist (mainly stamping dies & fixtures) and then was offered a position as a manufacturing engineer at the company where I was working.

As a manufacturing engineer, my core focus was serving Fortune 500 customers in the construction and agricultural areas.  Five years later I left that company for another manufacturing (OEM) company and spent the next eight years working in sales.  I was the sales manager of our “outside accounts” division.  We were a contract manufacturer for around 30 companies including a Fortune 500 construction/ag company.  After meeting and surpassing goals and expectations in that role, I decided to turn my focus to another area – overseas sourcing.

Utilizing my background in sales and manufacturing, DDI Inc. seemed to be a natural fit.  I have enjoyed the challenges and rewards of working with roughly 150 Chinese manufacturers to ensure high quality products are brought into the United States on time and on budget.  I look forward to many more years of serving the US OEM market in my role at DDI as part of our OEM team.
