I work for a family business and do a thousand little jobs. How do I put that on a résumé?

[BILL]

I would say something like:

Include the company name, etc. I wouldn't specifically note that it is family owned but don't withhold such information if asked.

Performed a variety of managerial and non-managerial duties including: sales, marketing, and customer service.

If you need something further to fill out your resume, I would break each down into specific areas.

So for sales, include your best, relevant sales experience. Be relatively specific but not wordy. Follow suit for your other fields.
