Core Values


It’s about balance. We realize that architecture is not about architecture all the time. We strongly believe that to be a great architectural firm, we must also be good corporate citizens. To get there we must be giving back to the different communities we live in: professional, family and friends, our neighborhoods and our city. For Carpenter Sellers Del Gatto Architects, we’ve made it about contributing to the AIA, interns, professional and community organizations and helping advance our profession by mentoring young students. We’re volunteering with charities and giving of our time and resources to help improve our community. These are the pursuits that continue to guide us to be better architects.

“Designing the environment for human activity to enhance every aspect of life including work, play, introspection, religion, education, “you name it” is truly a privilege. However, the CSD approach to creating these spaces and emotive environments goes beyond the creation of the end product. CSD design  process and approach envelops and gathers all the available resources within and outside the company to address the needs and success of the individual projects.

CSD is about people and the  need to create stimulating and fulfilling physical environments that exceed the project’s  expectation. Enough said….  what could be better than being part of that process…. and have FUN at the same time! Does it get any better?”

The CSD working environment  is a collaborative non-confrontational interchange of ideas, visions, approaches, solutions, relative to creating spaces for various functions. Each endeavor presented to CSD from the outset is considered without preconceived parameters in the attempt to foster new and creative problem solvi
