I had the opportunity to work with Quantum Investigations recently on a personal matter. I do not live in Arizona, but I needed surveillance there. I was able to reach them immediately, they went to work for me on very short notice, and they got the information I required to put the matter to rest. I was very pleased with their discretion, confidentiality, professionalism and communication. They were very easy to work with. I would not hesitate to hire them again.
Thanks again, Jeff.
Warmest regards,
Jeanne
I am a returning customer, based prompt service you provided me on another occasion. At this time, I want to Thank you for locating my father.
Prior to using your investigative service, I had utilized the online people search programs to locate my biological father, which I had not seen him for 20 years. I had leads, I came up with names, old addresses and phone numbers that were all dead ends or minimal information. I also utilized the Department of Motor Vehicles, with no response from them. My only chance was to pay a private investigator which I found you from another service you provided. I provided you the little information I had at approx. 8pm in the evening, immediately you responded reassuring me you had a phone number and address to locate the person I was looking for. The next day at 7:30am I made a phone call to the number you provided, I left a message. The same day at 6pm the father I had not talked to for 20 years had returned my call and we heard each others voice. It was not even 24 hours from start to finish. Thank you for the expedited service you provided, and being a key role in ending the search. All my friends and family’s first question is "How did you find him?" I simply reference your service.

I would like to thank you for the wonderful job you did for me in finding a place of employment of someone I have been looking for. The person I needed to contact owes me money and I have not been able to get a hold of him any other way. You got my information to me very quickly and 100% accurate. The fact that you went above and beyond with the records shows your value customer service. Your prices were very reasonable and your work excellent. Thank you again for your help.

ANASAZI Foundation retained the services of Quantum Investigations to locate a juvenile runaway from our program. After searching for 2 days we were unable to locate the runaway and called Quantum Investigations for assistance. Jeff was able to get right on it. There was not much information to go on, just some hearsay and a few possible references for some friends of the runaway. The Quantum investigators were able to find the young person within a few days as a result of thorough investigating and utilizing their resources. I highly recommend Quantum Investigations for any investigative needs.

Dear Jeff,
On behalf of Central Phoenix Acceptance, I would like to thank you for the great job you have done on our accounts.
The very first account I gave you on September 24, 2004, you were able to locate a debtor no one could find. Not only did you find my debtor by October 10, 2004, but you got him to call me regarding fire damage to the vehicle he let repossess, which helped me file the needed claims to recover our money.
On October 1, 2004, I gave you another account, by this time I had used three different repossession companies, none could locate the vehicle or the debtor. Once I gave the account to you, things started looking up, our debtor had disappeared since February!
Not only did you contact our debtor, you also found the vehicle at an impound yard.
I would recommend your services to anyone who has a skip or difficult customer. I can not thank you enough for your assistance with our difficult accounts. I am sure we will continue to do a lot more business together over the years.
Thank you again!

As a former Phoenix police officer, Jeff brings a unique insight to officer interviews and depositions. Jeff always responds promptly to my request even when contacted at the last minute. Jeff remains a professional throughout any service he provides and it is a pleasure to do business with him.
