“As a self-represented litigant in a protracted legal proceeding, I engaged AOSG for surveillance and documentation to accurately refute specific inaccuracies by the other party. The team at AOSG were able to quickly grasp my requirements, provide me with a reasonable quote and update me as they proceeded. The subsequent report was concise, the investigator was available to the courts for cross examination and I appreciated their knowledge, speed, accuracy, and professionalism”
