"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"Excellently well! Sandy helped me coordinate the inspection expediently. We were on a tight timeline and she pulled some strings so we could get the inspection done in time. Our inspector/structural engineer, Erinn, was personable, thorough, knowledgeable and timely. I highly recommend him and Alpha Structural!"

"After having remodeled our kitchen several years ago, we had KN remodel our master bathroom. Great guidance, from the construction stuff we don't understand to the aesthetic discussions we much appreciate. Done on time, and with great clarity around the billing. And the crew was great -- neat, thoughtful, on time, helpful. A big thumbs up."

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

"We hired Curt Sturgill to design an addition and remodel of our home in Pasadena. Curt was a pleasure to work with and regularly kept us updated throughout the design process, the drafting of construction documents, and final approval of the plans by the city. Our project involved the addition of a master suite and a complete renovation of our kitchen, and Curt was very helpful in helping us bring our vision to a reality. He understands how to work with the city planners and building department and was able to handle any concerns they had in a timely manner, so that our plans could be approved. We were very happy with the architectural and design services provided by Curt. He is very easy to work with and a great architect."
