"Tolga was very professional and far exceeded our expectations. He drew up our structural plans very quickly and was easy to reach whenever we had questions. I would highly recommend TY Engineering to anyone looking for a structural engineer, and if I need one in the future they will be the first I call."

"Wow! An honest contractor who responds immediately. After looking at my concrete situation, he identified the problem and recommended a quick, inexpensive DIY solution. Great to see honest, sincere people still are out there."

"My residential construction project was abruptly put on hold when a city inspector required a survey to verify the property boundaries. Unfortunately good surveyors are in high demand (at least 4 weeks out), and Voorheis and Voorheis was no exception. However, after discussing my job with Jeff, he thought he'd be able to work it in very soon between other clients. Jeff patiently answered my questions, and I ultimately felt confident to hire them for the survey. I was really happy with their thoroughness and professionalism, and ultimately the city inspector was satisfied and approved our setbacks. Thanks to Voorheis and Voorheis for getting my project quickly back on track with their excellent and timely work!"

"Excellent experience again with Alpha Structural. Charlie Rosenkranz came to see the 3-story apartment building in West Hollywood. We discussed what the soft story retrofit plans will likely include. He's knowledgeable and experienced. We appreciated his professional no-pressure approach and answering our questions. Alpha performed an exploratory investigation of the support structure, as architectural plans were not available. They engineered the plans with city approval. They then consulted with us and provided the approved THP (Tenant Habitability Plan) paperwork. Production Manager Dave Schlaich and Job Supervisor Seth Price met me before construction. Dave went over the approved plans and explained the work that would be performed, and the purpose. They both answered all my questions. Lawrence and Antonio were the main work team. They were very pleasant and answered all our questions. Both had great explanations with Lawrence being very detailed. Seth provided timely progress reports by phone and text. He answered all questions, and provided contacts for automatic shut-off gas valves and stucco work. Despite Covid-19, they scheduled and passed inspections, and completed the work in under a month. We've seen projects by other companies stuck in limbo for months with no progress, so we chose Alpha to avoid complications. They removed all debris, and left the property clean. The tenants and neighbors had no complaints. Daniel Aparicio also explained various issues. Communication with everyone, including the office staff, was excellent. We're very pleased with this experience."

"If you?re here looking for an architect, look no further. Francisco is the man for the job. He helped us with a garage to ADU conversion. Francisco kept us informed and communicated with us throughout the entire project. He was very professional, helpful and patient. We had tons of questions and he had the answers. He is very efficient and great at his job. We would hire him again with no hesitation. Thank you Francisco for making for making this process a breeze!"

"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."

"After initial consultation by phone we quickly scheduled an appointment. The construction engineer came in 2 days, reviewed our project and provided supporting documentation for our needs. Highly recommend!"

"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."
