I saw Dr Nguyen the first time for a free consultation. I had a quote by another doctor for a $6300 treatment plan (5 crowns plus exam and xray). I hid this treatment plan from Dr Nguyen. Since I brought my own xrays, Dr Nguyen reviewed them and looked inside my mouth. He proposed 3 crowns and not 5. I asked him why he did not think that I would need 2 more crowns. He professionally explained to me the reasons, not only with the layman terms but also with the engineering principles (I happen to be an engineer). Since Dr Nguyen charges for $650 cash per crown, my bill went from $6300 down to a little above $2000. I got the 3 crown done 2 weeks after that. On the seat crown appointment, after a minor adjustment and checking, he also took an xray to make sure that crowns fit well. Best of all, he even offered me a 5-yr warranty on these crowns. Since then, I have become a regular patient there.
