“Compliance Pros has been such an asset to our construction team. They are knowledgeable, cost effective, and easy to work with. I trust them to make sure our team stays in compliance. Their reports are easy to access, and they are flexible in providing additional information as required by specific clients. They even voluntarily proposed a price reduction when we had multiple projects in close proximity. I would highly recommend working with Compliance Pros!”

“I’ve only been working with Compliance Pros and specifically Emma DiPaolo for the last 6 or 8 months. I’ve worked with other companies who do what CP does but there is something different about these folks. Emma is an outstanding inspector!!! Very knowledgeable of the rules and regulations of multiple counties E&S programs and supplies complete and thorough reports in a very timely manner. She is always open to communication and discussion of any issue that may arise and always has a solution at hand.
