Sentinel Power Services, Inc. was founded in December 1998 as a breaker repair shop for industrial clients in the greater Tulsa, Oklahoma area.  In 2002 Sentinel transitioned to being a solutions provider by expanding its capabilities to include electrical equipment testing, commissioning, and troubleshooting, as well as large motor expertise.  More capabilities were added in 2008 when Sentinel began to perform power system studies.

As client needs continue to evolve, Sentinel has added full service engineering capabilities and will continue to expand its solutions offerings. The skilled and experienced engineers and technicians at Sentinel Power Services, Inc. serve a wide variety of clients by providing a solid knowledge base of electrical design and power system preventative maintenance in order to help improve system reliability and safety.  Sentinel has offices in Tulsa, OK and Lake Charles, LA and is a member of the NFPA, accredited by NETA, and is a registered professional engineering firm in multiple states.
