"Pedro is a very professional Structural Engineer. Very knowledgeable."

"Mr. Castillo-Navia fulfilled all items in our wish list and designed a practical and beautiful home for our family! I hope this is our forever home but my wife and I would definitely look him up again if we need a different house when we eventually become empty nesters. He is professional and detail-oriented. CASNA Design even covered the structural engineering process. He answered immediately, is knowledgeable and passionate about his work, transparent in pricing, answered all of our questions and is very punctual. Mr. Castillo-Navia took the time to listen to what we wanted and made sure to incorporate that into our designs. We had the best experience. He was friendly, professional and we love the design he came up with. From the initial meeting to the final meeting everything went smoothly. He is very knowledgeable and a great listener. He also made himself available for follow-up questions from potential contractors and helped us compare bids. Working with CASNA Design was money well spent and we highly recommend him."

"It was such a great experience working with Dan. He is knowledgeable, experienced, efficient, and an overall pleasure to work with. As I have other building plan needs, Dan is my "go to" for sure!"

"Tim was very professional, he was prompt in responding to messages. He showed up on the time for structural inspection and did thorough inspection. I highly recommend him considering my earlier experiences with other structural engineers, how they carry out their inspections and never give any definitive answers."

I am a licensed Professional Engineer providing structural engineering services for residential and small commercial projects. I work with homeowners, contractors, and design professionals to help move projects through the permit process by providing structural calculations, drawings, evaluations, and engineering letters as needed.\n\nIn-person structural inspections are available in Maryland, DC, and Northern Virginia. Remote structural consulting is available in Delaware and North Carolina.\n\nTypical projects include load-bearing wall removal, beam and header sizing, additions, decks, foundation concerns, and framing evaluations. My goal is to provide practical, code-compliant structural solutions that are clear, efficient, and tailored to the project.

"Outdoor Artisan is as professional as they come. What i look for more than anything else in a contractor is communication skills. If a contractor cannot excel at communication then clients are not going to be happy. Outdoor Artisan was in contact with us every day of this project, even when we were out of town. We knew what was happening, who was coming and going and what they hoped to achieve each week of the project. In addition to the owner, Clive Newey, we worked with Jason Humphrey, our project manager. Jason has a very artistic mind, and was always suggesting ideas to enhance and build upon what we happen to be thinking about at the time; the stain color, ways to finish the structure with elegant trim, the cupola on top and the corner braces. We highly recommend Outdoor Artisan for any outdoor structure, hardscape or landscape project."

"Quick response when I called them. The report was ready when they said it would be delivered and they were available by phone to answer follow-up questions."
