From Rebbe to Renovator: The Unbelievable Journey of David Mashinsky

In this inspiring episode of the None of Your Business Podcast, Michael Greenfield and Ushy Schwartz sit down with David “Dudi” Mashinsky, a former Rebbe who went from teaching Alef-Bais with a guitar to leading multi-million dollar healthcare renovation projects. His journey is anything but conventional—and it’s packed with lessons on creativity, grit, and trusting your instincts.

David opens up about his early days in the classroom, using music as a tool for learning, and how his childhood love of doodling architecture turned into a real-life design empire. What started with one nursing home lobby has evolved into Dynamic Design, a one-stop-shop design-build firm that’s redefining the aesthetics of senior care across the country.

He breaks down how he transitioned from chinuch to construction, why most operators hate dealing with designers and contractors, and how his all-in-one solution has changed the game for healthcare facilities. From a flooded New Jersey nursing home reborn in six months to a million-dollar rehab gym in a cathedral-style chapel, David’s projects speak for themselves—but it’s the man behind the brand that will really leave you inspired.

This episode is also a must-listen for Rebbeim and educators facing burnout, or anyone contemplating a career pivot. David shares real talk about building confidence, learning from failure, and why chasing your passion will always take you further than chasing trends.

If you’ve ever felt stuck in a job, unsure of how to turn your side passion into a real business, or just want to hear the raw, real story of someone who made it happen against the odds, this episode is for you.

David “Dudi” Mashinsky proves that sometimes the most powerful transformations start with a guitar, a sketchpad, and a whole lot of faith.
