Our verification notes
Named PE and CFM engineers confirmed on government documents from four separate Missouri municipalities, not just the firm's team page. Note the distinction that matters for a building owner: levee certification and a FEMA floodproofing certificate are different instruments, and doing the first does not establish that a firm does the second.
