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.

He made sure that I was provided with best service and not being pushy sales forcing to make sales I would definitely recommend it More
