Testimonials provided by our private investigation clients:

“Once again, thank you for all of your hard work and your professionalism. Our company and our employees are now safer, moral is much higher and everyone feels better knowing you found the thief and allowed us to fire her and have her prosecuted.”

E. Martinelli, Vice President – Human Resources, Orlando, Florida


“ASG did a superb job! They were able to obtain excellent photographic evidence, both inside a dimly lit restaurant and outside at night. Their work leaves no doubt as to the nature of the relationship between the two targets of the investigation.”

J. Kelly, Miami


“Thanks for all your help. I will stay in touch and gladly use your service again. Because of your help, the truth finally came out…”

J. Ridlock, Michigan


“I am pleased to recommend ASG to anyone who might benefit from their services. Recently, my wife and I were having difficulties after 16 years of marriage. A former colleague of hers began aggressively pursuing her. I retained ASG to learn what was going on. They responded quickly and professionally. They provided timely feedback and were always able to adjust to my schedule, even on short notice. Because of the thorough, professional work of ASG, I was able to learn exactly what was and was not going on.”

M. Kelly, Texas


“I would like to thank you again for the professional handling of my request. I was hesitant to hire a private investigation I found on the internet, but you handled every step professionally and ethically. I would not hesitate to hire you in the future. I admire you and your researchers for the work they did.”

G. Lee, South Carolina


“ASG was able to locate the men who ripped off my elderly parents and guided the police to them. We owe you far more than the money we paid for your services. God bless.”

R. Armstrong, Ft. Lauderdale
