I have been working with Griggs Systems for over 12 years and Katia has always provided viable solutions to our cladding and fenestration detailing and specification questions. Her knowledge about the industry is superb, and her friendly support in accessing technical or cost issues from suppliers and their engineers is timely and reliable.

Kava Massih Architects has had the pleasure of working with Katia Griggs for many years. We keep going back to Katia because she and her team are good at what they do. They not only help represent a quality line of products, but they go out of their way to help us find the best the product and application for each project.

Our office has worked with Katia Griggs at Griggs Systems for more than a decade. When we find ourselves scratching our heads trying to figure out if there's a better way to employ a new rain screen product we might have seen in a magazine, or what our options might be for metal skins or brick veneers we always reach out to Katia first. Katia gets materials in our hands quickly and provides us with useful information which allows us to quickly evaluate if our budget can support a given material. Griggs also has a deep knowledge of the technical issue associated with the various products that they represent. We recommend Griggs Systems without hesitation

Our experience with Griggs Systems over the past 10 years has been more than exceptional. Katia and her team have been partners with us in key projects, from beginning to end. On design-build projects where technical accuracy is as important as product availability and ease of installation, they provide the entire team (architects and contractors) with valuable and accurate information that we can provide our clients in order to make informed decisions. There is no other product rep group more honest when it comes to information about product suitability, availability, durability, and cost than Griggs Systems.

Over the past 6-7 years I’ve had the pleasure of working with Katia on some pretty complex exterior envelope projects and have always appreciated her knowledge and candor. Whenever tricky detailing needed attention, her proactive approach of getting designers and manufacturers to the table, to work things out, was refreshing. She’s also not shy in getting the manufacturer’s help when she doesn’t have the answers, avoiding guesswork. I’m happy to say, since that first project we worked on together, because of her impeccable reputation, her involvement with more design teams and projects from our office has grown.

Hannah Moyer, Sr. Project Architect
Griggs Systems has been supporting the efforts of our offices for the last decade, if not more. Whatever our challenge, whether it was a small project or a detailing issue, we received their complete support. Griggs Systems, and specifically Katia, have become our go to representative and our first step in the specification of any exterior product for our projects. Whatever our challenge or design intent, we know that they will have a system for us, can educate us on the advantages, and have the expertise to install it. In many cases, Griggs Systems went far beyond the normal project representative by personally introducing to us new products, training our subcontractors on the installation, reviewing shop drawings, and meeting us in the field to resolving issues. We have an extreme comfort level when it comes to the products Griggs Systems represents.

Katia Griggs quickly became a favorite of our San Francisco office for her attention to detail; her skilled mix of vendors and her responsiveness. As we’ve gone into work-from-home mode for the past 20 months, she has continued to be responsive on our projects and truly help us with our clients. Her product mix is thoughtful and contains a full range of manufacturers that allow us to really accommodate the high performance needs of our clients.
