I have had the pleasure of knowing and working with Mark Marenghi for nearing 20 years, collaborating regularly on building scenery for a Boston Ballet.

Mark's creativity, attention to detail, and engineering expertise consistently result in high quality solutions that have elevated many productions. His ability to transform concepts into reality is truly remarkable. Whether it's small intricate stage props or large-scale scenic pieces, Mark's craftsmanship and dedication shine through in every project. What sets Mark apart is his problem-solving approach and ability to adapt to the unique needs of each project. His professionalism, innovation, and commitment to excellence make him an invaluable partner. I wholeheartedly recommend Mark for any design, fabrication, or engineering work—he is truly a master of his craft.

- Ben Phillips, Director of Production at Boston Ballet

Mark is one of the fastest technical designers I’ve ever seen.

He is a true collaborator, bringing his wealth of expertise in fabrication to inform the design and improve the finished product. We iterated quickly through a fast-paced project. Mark was impressively nimble, testing different approaches to rapidly refine the design. To meet the demanding timeline, he pragmatically released drawings in stages so fabrication could begin on schedule. His flexibility was key to the success of the project. I couldn’t be happier with MJM’s service and look forward to working together again soon.
