"I had an urgent request to get a permit across the line and Pedro was on his A-game and helped me within hours. Very professional, well documented, etc. Other structural engineers I hired only gave me headaches. I'd use Pedro again any day. Thank you very much, and glad to be in business with you!"

"Jeremy was great to work with and very detailed and professional with his review of my homeâ s structure as well as the report he provided. Based on his findings I did have work done on my 62 year old home foundation to hopefully insure I get another 62. Thank you Jeremy!"

"Working with CASNA Design was the best of experiences. My husband and I had never worked with an architect before. Mario was patient, answered all of our questions, and was extremely knowledgeable. He kept our mind at ease throughout the entire process and had true excitement around making our project a success. We will definitely use CASNA Design services again!"

"Bryan was extremely knowledgeable and prompt. I would recommend him to anyone who needs some engineering done."

"Hired A+ after considering several other drafters. After they were complete, we paid an licensed NC Professional Engineer to review the plans. The engineer complimented A+'s work and said he was a 'smart guy'. Nearly everything in the plans was spot on. They worked quickly, communicated and worked well by email, very responsive. Will hire again and recommend. Thank you..."

"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.
