J.C. Dendis Construction has performed as a subcontractor for our organization for over 20 years. They have proven to be a reliable contractor providing quality services. We highly recommend them for any excavating, trucking and site work that you may require.

-Craig Sessler, Co-Owner, Sessler Wrecking


I have worked with John Dendis on several occasions over the last 15 years. I have built several car wash projects in the Finger Lakes area. I would not call anyone else when it comes to site work. John is a very talented heavy equipment operator. He also goes beyond the art of operating the equipment. He is a business man in every sense of the word. His vast knowledge is invaluable to any project. I highly recommend Dendis Construction.

-Robert Marchenese, President, Auto Wash


Keeping our project on schedule and within the budget could not have happened without your team, thanks for working so closely with the other teams, John.

John Dendis worked on a project for the county which I was in charge of. It was an ecologically sensitive area. It involved a village water supply as well as four different owners. The work was done quickly, efficiently, and professionally. There were erosion problems as well as wash out under buildings. Everyone was pleased with the outcome.
