Mary Feinberg

Mary handles all business development for Triple knot. Her day job as a passionate mission-driven fundraiser brings with it a strong sense of community engagement and drive to cultivate client relationships.

Tedy Feinberg

Tedy is officially on the payroll in snacks and high-fives. While his reach may be short, his enthusiasm is limitless—specializing in holding flashlights at almost the right angle and offering unsolicited design opinions. He’s learning the family trade, mastering the basics of measuring twice (sometimes three times), respecting tools, and understanding that sawdust is a badge of honor.

Lead Designer

Jack Feinberg

With a résumé built block by block, specifically from magnatiles, Jack brings hands-on experience balancing form, function, and structural integrity. Known for his ambitious angles and firm belief that triangles make everything stronger, he reminds us that great design starts with curiosity and creativity. While his tools of choice may still be magnetic, his bold eye and imaginative ideas influence everything we build—proving that good design doesn’t come from a rulebook, but from seeing what’s possible.

Finish and Materials Specialist

Benjamin Feinberg

Renowned for almost staying inside the lines, Benjamin brings that same fearless precision to finishes, stains, and material choices, carefully evaluating each option based on texture, color, and how fun it is to touch. A hands-on tester of surfaces he keeps us grounded in the truth that the best finishes don’t need to be flawless—they just need character. After all, a little personality is what makes a project truly finished.
