“MARN opened doors...

to business opportunities, we would have not been aware of. Marnee knew exactly what industries to target on our behalf to secure projects that fit our capabilities ... I'm currently looking for more rep firms like MARN."

—Ken Pietrzycki | Director of Sales | Laszeray Technology, LLC

“In the short time…

that Marnee has represented Marion, she has proven herself to be more than just a sales rep. She is a team builder – bringing a wealth of experience, services, and outside-the-box thinking to the table. Her energy and enthusiasm have been instrumental in re-engaging our New England customer base as well as engaging new customers in new markets.”

—Douglas Johnson | President, Marion Manufacturing

“Onshoring our products...

is a big decision, but Marnee is with us every step of the way - helping us determine how we might migrate to US suppliers to improve parts quality and delivery times without disrupting our inventory demands.”

Joshua B | Director of Product Development

“Quality, working parts…

are getting to the customer in a timeframe that used to be impossible – and all from the comfort of our own homes! The price point of a relatively large quantity MJF 3D printed parts has been a game-changer; we’re really enjoying the leverage that this technology is giving us!”

Scott C | Sustaining Engineer

“Marnee’s done the research...

vetting every supplier she represents to ensure they produce consistent quality, can handle volume demands, and are fiscally stable.  She really understands manufacturing.”
