Sternberg Lighting Announces Leadership Changes Amid Strategic Reorganization
On October 9, 2025, Sternberg Lighting unveiled a new leadership structure following the departure of President John Geagan, who is leaving to lead Diversified’s New York office. Promoting from within, Mike Renner has been elevated to Vice President and General Manager, while Mike Rivera steps up as Senior Director of Sales, and Derek Emeson becomes Director of Marketing and Product Management. This transition coincides with Sternberg’s recent merger with Lumca, creating a unified platform for site lighting that blends traditional and contemporary designs. Geagan’s new role at Diversified emphasizes building trust and strengthening relationships in a competitive market, particularly as the company restructures after losing a major vendor.
