NEW L.A. Office

DTR Los Angeles Office


DTR Consulting Services, the "Building Science Guys", have opened a new Los Angeles Area Office, just north of the downtown area, to better serve our Clients in the L.A. metropolitan area. This office is in addition to the current Orange County office in Irvine and two other northern California offices. This new office location allows for the continued expansion of DTR and also serves as a central location to service our clients in a more efficient manner.

Overseeing this new office is the Office Leader | Senior Building Envelope Architect, Kirk O'Brien, AIA, RCI, NCARB. Kirk brings with him a long history of experience and connection to the local community. DTR Consulting Services continues to work with Building Owners, Developers and Architectural/Engineering Clients in the Los Angeles, Orange County and San Diego Area since early 2003. This move allows DTR to build upon our current client base and to expand our Firm to better serve our current and future A/E Clients.

DTR will also be recruiting the best new technical staff, the area has available. He will be in charge mentoring new staff members into the existing DTR Culture and provide guidance for both experienced and junior members in the DTR approach to serving our Architectural Clients. DTR will be looking to hire both Building Envelope Consultants specialized in Building Science, Technical Architects, Specifiers and Field Quality Control Staff.

Low VOC's

High Performance Coatings

While exposed structural steel was once the select province of a few noteworthy projects, architects today are increasingly using transparency in their design.


AESS & Glazed Structure


Curved Curtain Wall & More

Curtain walls are not all the same. Each individual project should be reviewed for exposure, use, esthetics and function before selecting appropriate systems for your project. Transitions and terminations of systems are of particular care.

Cold Fluid Applied Waterproofing
