Word-of-mouth leads in Denver after 17 years as a retail manager

A friend who works at a local manufacturer says there are openings not advertised online. I do not usually post, so bear with me. One is a print shop, one is an accounting firm and one is a clinic. Does anyone have similar leads?

Keep a list of who you contacted and when. It makes follow-ups easy.

Visiting in person worked for a trades job. For office jobs, email was better.
