Our story began in 2008 where Alpha Excavation, a family-owned business led by President Jason Stenger who was raised on the Island Maui and Vice-President Tiffany Stenger, embarked on a remarkable journey with a single piece of equipment. Today, we have grown into a full-service construction company specializing in Heavy Civil Construction, Water Well Drilling, Underground Utilities, Concrete, and Renewable Energy. We pride ourselves on offering a wide range of services to meet diverse client needs.

​Production, quality, and customer service are of utmost importance at Alpha Inc. We have earned a strong reputation as a dependable and trustworthy partner in construction projects spanning across Hawaiʻi, thanks to our unwavering commitment to excellence. Our company is deeply committed to practicing sustainability and environmentally responsible methods. By leveraging cutting-edge technology and a dedicated team, Alpha Inc. guarantees top-notch outcomes throughout every stage of the construction process. We take a collaborative approach, overseeing each phase from initial proposal to final deployment. Our goal is to ensure that each project is customized to meet the specific needs of our clients while adhering to the highest standards of quality and sustainability. 

​In addition to our construction services, Alpha Inc. is wholeheartedly dedicated to making a positive impact on Hawaiʻi and its residents. We actively participate in the progress of renewable energy solutions and the development of crucial infrastructure.
