To all potential and current Infiniti customers, I'd like to introduce myself to you as a highly energetic asset to the Infinit of Gwinnett dealership! I'm a retired service member that served 22 yrs of active duty service in our beloved US Army Infantry and immediately after deployed to Baghdad to work alongside our Ambassador at the New Embassy Compound in Iraq. In addition, 9 years of high level security contracting throughout the US! Originally from upstate New York (Syracuse area) but here to provide service and be the best that I can be. I'll end this short bio with my hobbies for all who love a particular discipline. Mine happens to be boxing, boxing and oh yes...more boxing!!! Please come by and ask for me! With our team I'll assure you that you will receive the greatest customer service that you could possibly imagine and 100% of my undivided attention to YOU as the customer. You will not be disappointed and I hope to hear from you all soon.

I had the opportunity to meet two great sales consultants Darryl and Mark. Darryl was the 1st to assist me with the test drive of my purchase of interest but due to unforeseen circumstances he had to refer m Darryl and Mark. Darryl was the 1st to assist me with the test drive of my purchase of interest but due to unforeseen circumstances he had to refer me to Mark who helped assist with me confirming that I was making the right purchase for myself. Mark was very detailed in showing the specs of the vehicle. Any questions I had he was a straight shooter in answering. He’s very prompt also and I’m sure that has a lot to do with is military background. I’m grateful for the assistance provided in helping me make one of my dream purchases. Looking forward to referring others and hopefully making another purchase in the future. More
