"Ryan and team did a fantastic job of helping us with a project to repair a beam that was structurally unsound. We were kept very well informed of all key events and as usual (we’ve worked with Ryan several times) everything went without a hitch. Ryan and team do an outstanding job, and we would not hesitate to work with them again."

"The process working with Char to develop a set of design plans for my master suite addition has been fantastic. She has worked with me step by step, explaining the process at each point and what I can expect. She also listened to what I was looking for, drew up various designs, and then worked with me on modifications. She was a partner in the process the entire time, not only treating me with respect and professionalism, but talking through options and pros and cons with me so I ended up with the design I really wanted. Throughout the entire process I felt like I was in good and trustworthy hands. So much so that I will continue to use Char's assistance as I move forward on next steps with this project."

"Ward Engineering began working with Jared of Cornerstone Home Designs approximately 3 years ago to perform residential design work using Chief Architect design software. I find Jared to be the most capable Chief Architect designer I have ever worked with. Jared is very efficient and thorough at developing the residential Chief Architect models. In addition to being competent, Jared makes himself available to provide personal 1-on-1 training over the internet, which has been a huge blessing to our company and clients."

"I used Triple V as the Project Engineer for a garage conversion to single family residence for my son’s family. Vic not only did the engineering for us, he also did the structural drawings we submitted to the county as part of our permit package. He delivered the plans promptly, and worked collaboratively with us to resolve issues we identified and revise the drawings accordingly. The county building department approved the plans and issued the permit. During the project construction Vic patiently responded to questions from us (we’re DIY’ers, not professional builders) and offered/provided certifications to revisions we jointly agreed to. Overall, Triple V provided what was promised at an outstanding value."

"I had the pleasure of working with Bryson on a recent project, and I couldn’t be more impressed with their work. From start to finish, Bryson demonstrated extensive knowledge and expertise in structural engineering. They took the time to understand the project’s unique needs and provided clear, practical solutions that ensured everything was both safe and efficient. One of the standout qualities was their excellent communication. They kept me informed at every stage, answering questions promptly and offering advice when needed. Even when challenges arose, Bryson approached them with professionalism and a problem-solving mindset, ensuring that the project stayed on track. The quality of the work was exceptional. Every detail was carefully considered, and I felt confident in the structural integrity of the design. Bryson truly went above and beyond, offering both technical skill and a genuine commitment to the project’s success. Thank you and I look forward to working with you again."
