What our clients are saying

  • With DCA’s approach and preparation, the Galt Elementary School District, is very happy with the results. DCA has met and exceeded the district’s expectations with several projects. In my past work as Deputy Superintendent of Administrative Services at Sacramento City Unified School District, I oversaw over $200 million in construction projects, and I can say that DCA would be a partner I would seek for all projects.

    Tom Barentson
    CBO (Retired) | Galt Joint Unified School District
  • The Roseville City School District went out for a design-build RFQ for a new elementary school in the spring of 2018. DCA separated themselves from the competition due to their ability to listen intently to our needs, seek feedback on their conceptual designs, and commit to meeting the strict timelines. The school design exceeded our expectations.  Based on our experience, we look forward to partnering with DCA on future projects in the Roseville City School District.

    Superintendent | Roseville City School District
  • DCA has assisted us on several projects going back to 2014. They helped us successfully deliver out Prop 39 energy efficiency projects as well as the replacement of the main entry road to our campus. As the new member of our team, they jumped in, providing much needed leadership to our group of stakeholders and pre-existing consultants, which allowed us to deliver our projects on-time and within budget.

    J. Arturo Reyes
    Superintendent/President | Mendocino-Lake Community College District
  • Through a combination of technical expertise, collaboration and customer service, DCA helped us become one of the first small districts in California to gain funding approval for our Prop 39 projects. The DCA team exhibited first rate professionalism, excellent work ethic, and worked with successfully with Trustees and staff to maximize optimal service to our learning committee.

    José L. González
    Superintendent | Planada School District
  • Over the past 25 years, DCA has been partnering with our District on a variety of projects. DCA has presented a level of professionalism, teamwork and creativity that we do not always experience with other architectural firms. The DCA team always listens and responds in a timely manner with solutions and options. This all-encompassing professionalism has made DCA a pleasure to work with—something we look forward to for many years to come.

    Steve L. Breakfield
    Director of Facilities & Planning | Stockton Unified School District
  • I have worked with the DCA team on three projects. I have found them to be very detail-oriented and to produce very tight and accurate documents. They listen to what I need and focus on my priorities.

    Fernando Nieto
    Director of Facilities | Soledad Unified School District
  • It was a pleasure working with DCA on the Jesse Sanchez projects. Their professionalism, knowledge, and understanding of the project and needs of the owner, and the ability to work hand in hand with the contractor created a successful project from the beginning. Their team was sensitive to the constraints of both the budget and time, continually pushing the project forward. Because this was a “fast-track” project, the quick attention and response we received from DCA on every issue made this project a huge success.

    Sharon Dilbeck
    President | Dilbeck & Sons, Inc.
  • I have worked with Juan on numerous projects that had very tight budgets. His ability to manage the design and keep the project on budget is amazing. I feel like Juan really listened to our priorities.

    Jose L. Manzo
    Superintendent | Oak Grove School District
  • The DCA team led the implementation of our Master Plan for the past four years. Their interpersonal and facilitation skills have led not only to successful projects, but just as importantly, to a group of constituents that felt listened to.

    Superintendent | Calistoga Jt. Unified School District
  • I have worked with the DCA team on multiple projects for our District, most recently on a new school campus. They pay constant attention to our needs, are good listeners and a genuine team players. We have given DCA our most important projects, and they have always delivered for us.
