ProTelesis Corporation is a San Diego-based managed services provider (MSP/MSSP) born from the 2019 merger of two California telecom heavyweights - Protel (a leading Mitel Blue dealer) and Xtelesis (a leading Mitel Orange dealer). The company has evolved from a traditional phone-system business into a full-stack technology partner delivering managed IT, cybersecurity, unified communications, cloud, structured cabling, and managed detection and response. With offices across California, the Pacific Northwest, Utah, and Bangalore, it supports thousands of clients and hundreds of thousands of endpoints, with a focus on biotech, defense, and growing small-to-midsize businesses.
Mike Promotico is the President and CEO of ProTelesis Corporation, a San Diego-based managed IT services provider he has helped build into a West Coast powerhouse over 37+ years in telecommunications. Starting as a principal at INet Corp in 1987 and helping grow it into one of North America's largest Mitel resellers, Promotico has spent three decades bridging the gap between traditional telecom and modern IT - co-founding Technology Assurance Group, leading Standard Tel Networks, and ultimately guiding ProTelesis through eight strategic acquisitions including the 2025 cyber-physical convergence play with Amer-X Security. Under his leadership, ProTelesis manages over 100,000 endpoints for more than 10,000 customers across the U.S.
