I would recommend against using his services. Go to Yelp and take a look at my photos so you can see for yourself the quality of care that I received from him.

I don't know if it is due to Irvine Hospital's shut down or what, but he does not care at all for his business. There should be a new word for his level of arrogance. He punished me for choosing not to go with sedation by injecting literally 25 local shots, the most painful thing in my life, I almost fainted. His facility is so outdated, he can not tell if you have enough bones for implant or not, he opens up your gum to evaluate that. Consider 3 to 5 surgeries when you walk in. Put aside $6000 for just an implant (no crown).

He is a NO-NO. I never forget the horrible experience that I had with Dr. Hasse. For an implant he charged me a total of $3325+750 and was asking for $2000 more and when I refused to pay that, because he never told me about it upfront, he refused to treat me. I am happy after all, that he refused to give me service, and I was forced to get out of there, otherwise who knew, I had to probably undergo couple of more unsuccessful surgeries. The place that he removed some bone from my chin is still numb after almost a year and the spot where he did the stitches is visible on my face. He wanted to get some more bones from my hip and put it in my mouth, but I resisted to do that. He also wanted to break my jaw to three to five pieces and move them back and forth in order to redcue the size of the opening by 1mil. If you want to go to him, don't bother, donate some $4000 to some charity and go somewhere else, you will feel much better and safer.

Dr. Hasse is the most professional dentists I have met. He is the best of the best!
