Customer Testimonials

GSI-imageThe background check reports are exceptionally quick and easy to access. These reports are clear as far as giving detailed pertinent information on a person’s former address, aliases, criminal arrest and conviction history. Since we have been using the services, we have not had any issues or any need for further assistance because the system is user friendly.

Grand Slam Investigations recently helped our company track down the source of an IP address. In less than an hour I had my answer.  Grand Slam has given our company immediate attention on questions for our background requirements for our company’s employees as well. We are glad that they are part of our team and we cannot thank them enough for their efforts.

Grand Slam Investigations did a great job. They were quick and professional in finding out the information I needed. The investigator was very compassionate in delivering the news to me that no one wants to hear about their spouse. I am grateful for that. Grand Slam Investigations does a great job!!”

The main service that we are using is background checks for new hires. This service has been very well received due to the immediate and accurate results. We have also been introduced into a new service, Integrity and Aptitude testing which has been implemented into our internal and external hiring process.
