What SigmaPros does

SigmaPros LLC is a privately held renovation, fabrication, and turnkey construction services provider headquartered in Wakefield, Massachusetts. Founded in 2004, the company specializes in large-scale community-wide renovations of occupied apartment communities, multifamily housing, restaurants, and commercial properties throughout the Northeast United States. The firm has completed renovations on more than 10,000 occupied apartments, establishing a track record in the specialized niche of occupied-unit renovation, where minimizing tenant disruption is a key project management discipline. The company operates two physical locations: a corporate office at 910 Main Street, Wakefield MA, and a design-fabrication-distribution center at 227 New Boston Street, Woburn MA, branded as SigmaPros - Sigma Design.

SigmaPros operates an in-house fabrication workshop producing custom millwork (reception desks, communal tables, bookcases, wall panels, ceiling features), kitchen cabinetry, and cabinet doors under the guidance of a master craftsman. This fabrication capability supports rapid turnaround—cabinet doors in 7 days and full kitchens in 14 days—and enables customized solutions that third-party suppliers cannot match at comparable speed. End-to-end property transformation services span consulting, budgeting, permitting, fabrication, and construction, with electrical, plumbing, and HVAC capabilities integrated through subcontracted partners: D&M Elite Electrical Inc., Black Onyx Plumbing, and TESTERAL for premium aluminum and PVC doors and windows.

The business model is project-based, sales-led, and relationship-driven, targeting enterprise property owners, property managers, and real estate investment firms through direct outreach, phone sales (781-246-0477), a corporate website with live chat, and an online work order portal for established maintenance accounts. Named enterprise clients include Avalon Communities (across multiple MA and CT properties), Bell Partners, AVB Communities, and MNM Restaurant Group. The company appears to be family-led, with President Vojislav "Voya" Djordjic and Vice Presidents Daniela Djordjic and Aleks Samardzic in senior leadership, suggesting concentrated ownership and management control within the Djordjic family.
