In 1996, Craig Mills, P.E. and Steven Conoly, P.E. created Mills-Conoly Engineering, P.C. (MCE), a consulting electrical engineering firm. Presently, MCE is comprised of the two principals, two professional electrical engineers, and a part time bookkeeper. MCE provides electrical design, service and support to architects, engineers, government agencies, contractors and private businesses. Mechanical and plumbing engineering support services are provided through consultants selected by MCE based on project complexity. Both principals are graduates of Auburn University in electrical engineering and are registered professional engineers with licenses in most southern states. The two principal engineers combined experience includes over 75 years of new and renovation design in commercial, institutional, correctional, industrial, governmental and medical facilities. In addition to facility electrical systems design, the firm also provides medium voltage distribution design, short circuit, load flow, voltage drop and arc flash calculations, code research, interior and exterior lighting design, security (video and controll access) design, commissioning, and cost estimates. Craig Mills is a Registered Communications Distribution Designer (RCDD). Therefore MCE can provide standard compliant telecommunication design for all types of facilities.

Mills-Conoly Engineering, P.C. is dedicated to providing quality professional engineering services for diverse projects with varying degrees of complexity. The firm is small which allows the two registered principals to directly get involved and oversee all projects. The talented and experienced engineers provide great support and efficient work output. The firm strives for quality control in the design process which avoids construction conflicts. MCE also feels that providing service and support after design completion is important. MCE has performed commissioning services for a university dorm facility (9 buildings) and a data center. MCE is committed to utilizing qualified personnel, providing for their continuing education, and maintaining state-of-the-art hardware and software in order to produce a quality set of construction documents.
