Iyad is very professional at what he does , his services are worth every penny . Don’t think twice about giving yourself peace of mind . Great work , 10/10 stars
I hired and will continue to hire Iyan for both personal and work investigations. This man gets the job done right and he's knowledgeable, thoughtful, helpful and most of all he is confidential. However, he's upfront about all findings and won't sugarcoat. Be prepared for a result from Iyan. He's great!
The help that I needed was beyond what he could provide but he refused to accept any payment and offered advice to help me. Not everyone “just cares about money”. This is a good, honest man who genuinely wants to help people. Highly recommended.

Iyad was very knowledgeable in the law and made sure everything was done right and professional. Iyad has great pricing and always available no matter what the time of day it was .
