CM Buck & Associates

What CM Buck & Associates does

CM Buck & Associates is a family-owned manufacturer representative and technical solutions provider headquartered in Indianapolis, Indiana, operating across the Midwest (Indiana, Kentucky, Ohio, Michigan) since its founding in 1941 by mechanical engineer Chauncey M. Buck. The company operates three specialized divisions — Power, Lighting, and OEM — each staffed with dedicated division managers, field sales engineers, applications engineers, and project managers. Its customer base spans healthcare facilities, data centers, educational institutions, correctional facilities, water/wastewater infrastructure, commercial and industrial lighting end-markets, and OEM manufacturers requiring precision components.

The Power Division supplies mission-critical power infrastructure equipment sourced from manufacturer partners including ASCO Power Technologies, Toshiba, Schneider Electric, Active Power, Starline, and PG LifeLink, including uninterruptible power supplies (UPS), automatic transfer switches, generator paralleling switchgear, overhead busway systems, and generator docking stations. The Lighting Division distributes commercial and industrial LED fixtures and wireless control systems from partners such as Lutron, Current (ProLine), SLG Lighting, Vari-Lite, and Synapse Wireless, supported by photometric layout services. The OEM Division supplies pressure sensors, flow meters, solenoid valves, level controls, pumps, thermostats, and custom circuit boards from partners including All Sensors, World Magnetics, ASCO Numatics, Sika, and Thomas (Gardner Denver). Notable deployed projects include ASCO power infrastructure at Parkview Regional Medical Center, Eskenazi Health, IU Health/Riley Children's Hospital, and Good Samaritan Hospital ($109M BEACON Project), Toshiba UPS deployments at Lightbound and Fastenal data centers, and Starline Track Busway installations at Toyota Motor Manufacturing.

Revenue is generated through hardware distribution with manufacturer markups combined with technical services including engineering consultation, design assistance, project management, installation oversight, and ongoing maintenance. Pricing is quote-based and project-specific, with no public pricing disclosed. The go-to-market is a sales-led, enterprise field sales model with dedicated division teams and inside sales support. The company is currently led by President Steven Hall, representing the second-generation ownership lineage, and employs roughly 35-45 visible personnel across the three divisions, though actual headcount is likely higher given the regional field engineering footprint.
