Rose Martin

Business Office Manager

She / Her / Hers

Rose Martin is a seasoned event producer and project management professional, with a passion for radical hospitality, strategic planning, and innovative operations management.

She has a background in experiential marketing, producing activations around the country for national brands, such as Columbia Sportswear, Target, and Del Monte Fruits — a brand for which she fished a DJ booth out of the ocean at 3 a.m. Long story.

Most recently, Rose supported production of live events for Minnesota Public Radio, including Talking Volumes with Kerri Miller, Rock the Garden, and MPRs presence at the MN State Fair. She’s thrilled to further the mission of such an iconic Non-Profit institution through the work of Lunar Startups and the Glen Nelson Center.

When not dreaming up efficient ways to tackle business problems, Rose can be found jogging around Lake Como with her husband and daughter, researching the nagging question, Which pasta is best? (answer:  all of them), and working on her side hustle “Pun Intended”, a brand naming business based purely on word play.
