“S3DA contacted me through LinkedIn and while I am usually skeptical of cold messages, I was in need of an MEP engineer so I thought I would give them a shot. After more than a year of working on several projects with their team, I have found them to be responsive, reasonable with timelines and budgets, and willing to stand behind their work. While there are many good engineers out there, S3DA’s customer service stands out as a valuable resource.”
