Smart Start Ignition Interlock 5959 Shallowford Road, Chattanooga, TN 37421

"Very detailed explanations, could tell his goal was for me to succeed at this! Took exactly the amount of time he said and was very nice! Highly recommended!"

"I had a really good experience with John. He had a great personality and educated me flawlessly. Even though I am not happy with having a blow and go in my car because I had my DUI in 2016, I had an enjoyable experience and look forward to seeing John next month. Sincerely, Sarah Woodward Napier’s"

"Talks to my girlfriend like she's five yrs old. Yells at her when she doesn't breathe the way he wants. Refuses to calibrate her device on its last day working 2 days before Thanksgiving so she is stuck with no way to get groceries for holiday dinner or to pick up her son with the flu. Heartless, I suggest doing business with someone else!"

"John at smart start chatt was the best, he's good at his job and works in a timely manner. He also did some digging for me and helped me obtain my final calibration notice."

"Johnny Olivares is one of the nicest, helpful, and comforting people you will ever meet. This company is really helpful, but this location couldn't have treated me better. Even though this is court ordered, I still feel like these guys have my best interest in mind and really do appreciate my business. Definitely go here if you live in the Chattanooga area or surrounding cities."
