  “I’ve had a fantastic experience working with Jonathan and On Site Structural Engineering on two separate home projects – one in Lafayette and another in Erie. Jonathan was incredibly knowledgeable and efficient, and he always provided fair and transparent pricing for his specialized residential engineering services. Honestly, I’ve worked with numerous engineering firms throughout my career in signage, and Jonathan consistently stood out as one of the best – particularly for his responsiveness, expertise, and ability to come up with really creative solutions. I’d absolutely recommend him – 5 stars!” report abuse

  “I can’t recommend Dan and On Site Structural Engineering highly enough. As a custom home builder, I’m always really focused on staying on schedule and within budget, and Dan and his team consistently deliver. They’re incredibly responsive and always looking for ways to optimize the design to save us money and time. Compared to other structural engineers I’ve worked with, their turnaround time is fantastic – days instead of weeks! I’d definitely like to continue working with them on future projects.” report abuse

Jonathan, in particular, has been incredibly helpful, whether it’s managing complex projects like whole house designs or assisting with simpler tasks like beam sizing. They’re also reliable, completing work quickly and always offering fair prices. I wouldn’t go anywhere else for my engineering needs.” report abuse
