I came here today to leave a review for my Aunt Pat, who is a senior citizen that is probably the most particular and picky person about her vehicles! She will ONlY buy and have her service done from Cliff Mills, and more specifically have her service advising done with Jeremy Oliver! He is probably the most knowledgeable, but also patient and kind! Believe me, I know how my Aunt can be, and she doesn’t stop raving about how he treats her, and never makes her feel foolish for needing help! She always leaves completely confident in his work ...

I don't normally write reviews but sometimes when you get exceptional service, you have to give credit where credit is due!

I happened to connect with service advisor Jeremy - as a female calling about my vehicle it can be demeaning and I was expecting the same attitude I'd gotten with my first calls! That did not happen at all - he was pleasant, courteous, and very patient with answering my questions. He actually listened to my concerns and offered helpful advice without being condescending ...
