The integrity of a company influences the results it is capable of achieving.  Mark and Alan set the tone of how business is conducted by M. Harn Construction when they founded the firm.  All of our clients find them to be men of their word and MHC, too, keeps its promises.  At MHC, we are fair with everyone we do business with clients, designers, consultants, subcontractors and vendors; and we make it our personal responsibility that everyone is satisfied with their experience working with us.  This is who we are; this is the M. Harn Construction culture!

 Mark Harn began his career in the apprenticeship program with the IBEW. After 15 years as a Journeyman Electrician, Mark became a Field Project Superintendant. Over the last 15 to 20 years Mark has worked with some of the more notable Phoenix companies.  Projects ranged from tenant improvement to building stand alone retail stores, banks, warehouses and has extensive experience with data and call centers.
