New Hire Orientation

We hold New Hire orientation Tuesdays and Thursdays at 10:00am outside our office, 1612 SE Pardee St. Portland, OR 97202. This orientation provides you with information about our company philosophy, standards, and what to expect as a flagger employed by D&H Flagging.

During orientation you can fill out our more comprehensive application. After orientation, we hold screening interviews.

Going through orientation does not guarantee employment with D&H Flagging, but we are always looking for hard working, motivated applicants. We are entering our busy summer season and have many positions to fill.

It's important that you bring two forms of identification. A valid driver's license, social security card, passport, or birth certificate will do. You must have a working, reliable vehicle and a valid driver's license to work for D&H Flagging.

Please remember to bring your current flagger certification card to orientation as well. 

Due to Covid-19 safety concerns, orientation will be held outside.
