I stopped in to have a check engine light run a few days ago and Wesley was awesome! Our little dog was grumpy as yelling the whole time but Wesley was super friendly to our dogs.

I just want to thank Wesley for his help on Monday with my battery purchase and installation. He was very professional, knowledgeable and polite. Thanks, O'Reilly, for your very helpful staff....keep up the good work! DM
