Purpose.

Developing projects and buildings is just part of our main purpose – developing relationships. Whether that means developing relationships within the company, taking team members under our wing and helping them develop and grow. Or it can mean developing relationships with our clients and potential customers, committing to help them grow and succeed. By working with purpose, our leaders create the drive for others to work with the same aims.

Tenured.

Experience creates a culture that values knowledge and passes it on, helping every new member grow. With centuries in the field between them, our leadership team uses that experience as they help to develop our next generation of skilled project managers, field supervisors and craftsmen. Dome Construction has been an integral part of the Bay Area landscape since 1969, and our leaders are familiar faces in the construction industry.

Creative.

There is no replacement for innovation. The businesses and industry we serve don’t stand still, and neither do we. We find new methods and new approaches to help our projects overcome any obstacle, delivering what is most important for our clients. Our leadership team believes that, by setting the stage for our employees to explore new possibilities and showing the willingness to do it ourselves, we can continually evolve and find new, better ways of providing our clients the service they desire.

Passionate.

Passion is something that imbues each person. By showing passion – for the task at hand, for the safety of our teams, for the welfare of our Dome Construction family members – our leadership team seeks to build a company that we continue to be proud of, and that you can be proud to work with. Simply going through the paces isn’t good enough. Our leadership team is engaged, and drives engagement to create success.
