Dr Han is so good with my daughter.

Dental Associates Patient April 04, 2017
All of the dentists and orthodontists I had are amazing and very nice.

Dental Associates Patient March 20, 2017
Dr. Han is WONDERFUL!!

Dental Associates Patient February 19, 2017
Dr. Han took me out of the room to discuss my 12 year old daughter's care, which I found incredibly insulting to her. He then proceeded to tell me that he would not be able to treat her because of the crowding of her teeth, and her top and bottom jaw not lining up. According to him, the problem would be her inability to sit in dental chairs and the amount of patients they see. My daughter uses a wheelchair, so positioning her in a dental chair would take some care, pillows would probably work. I do not have a problem with him suggesting an orthodontist with more experience with special needs. The problem is he never mentioned not being able to treat her at any other appointment. When we consulted with him about an expander, he said she wasn't a good candidate and her top and bottom jaw lined up fine. We were told to come back in a year for braces. Now we're being told her mouth is a mess and he can't help. I asked for referrals, but he said he was unfamiliar with anyone that could help. Other than being in a wheelchair, my daughter is a typical 12 year old. She does not have cognitive delays. I'm incredibly disappointed in how we were treated.

Dental Associates Patient February 09, 2017
Dr. Han is amazing! Always extremely thorough and careful with me due to my TMJD! Absolutely fabulous!!!

Dental Associates Patient January 09, 2017
My husband and I were both comfortable with Dr. Han. We felt like we completely understood what treatment our son would need, why and how it would go. We also understood why some preferred options would not be possible for our son.

Dental Associates Patient December 10, 2016
assumed we wanted braces when it was a question, not an assumption. only presented one option. there must be other options.

Dental Associates Patient March 13, 2016
Every time I met with Dr. Han he seemed like he wasn't interested in my concerns and wouldn't spend very much time actually talking with me. When he spoke to me it felt like he was talking down to me instead of talking to me like he respected me.

Dental Associates Patient February 26, 2016
Once again, Dr. Hahn is great.

Dental Associates Patient January 02, 2016

The ONLY orthodontist I would ever consider using.

Dental Associates Patient November 09, 2014
Doctor was 40 minutes late for appointment that was scheduled for 8am. No apology or reason was given to us by the doctor. Since my daughter was missing school, I was not pleased.

Dental Associates Patient November 09, 2014
Love Dr. Han

Dental Associates Patient November 01, 2014
Didn't really provide care

Dental Associates Patient October 16, 2014
Hard to understand - Still calls me the wrong name after 3 years. Doesn't spend time with me.

Dental Associates Patient September 20, 2014
We love Dr. Han and his services are reasonable priced but your waiting area needs to be more comfortable if I am to wait that long.

I was late for an appt, my fault...and they got me in and so very nice about it. Very happy so far and was told on Friday's I could use they other Dental Associates which is closer to our house and very convenent. Thank You! .

Dental Associates Patient July 01, 2014
I felt very good after the the appointment.

Dental Associates Patient June 27, 2014
The dentist never addresses the kids about what he's doing. Nor does he talk to the parents.

Dental Associates Patient June 16, 2014
I felt he was very knowledgeable; did not try to "sell" me on anything - just relaying options and facts. I value that greatly in a professional.

Dental Associates Patient June 02, 2014
We are very happy with Dental Associates.

Dental Associates Patient May 18, 2014
They took my daughter back on time but she ended up sitting in the back for 20+ minutes waiting. It was supposed to be a "normal, quick appointment" but the appointment time ended up being 55 minutes.

Dental Associates Patient May 11, 2014
Ask the Dentist a few questions and he said that "Flo" would answer them and she didn't address my questions. I felt like my questions weren't important to her and I am still unsure of what will exactly be done on the day of treatment. I will be asking these questions again before any treatment begins.

Dental Associates Patient May 03, 2014
everyone was very helpful and kind

Dental Associates Patient March 25, 2014
Dr. Han is wonderful.

Dental Associates Patient January 24, 2014

Dental Associates Patient December 11, 2013
We like the dentist. It is the lack of availability and the length of waiting. Difficult for kids to miss so much school

Dental Associates Patient November 21, 2013
Dr. Han has very good "bedside manners".

Dental Associates Patient November 01, 2013
Dentist is kind and understanding.

Dental Associates Patient August 22, 2013
For our first visit, it did not seem that he spent much time reviewing her records or examining her. He did not ask for records from previous orthodontist. And he talked to me and got up to leave, I had to stop him to ask questions. Which he then answered

Dental Associates Patient August 19, 2013

Dental Associates Patient June 13, 2013
I'm 9 months pregnant and was very uncomfortable laying down. Dr. Han worked on me standing up for 4 hours. He was very understanding.

Dental Associates Patient May 09, 2013
My child felt very comfortable with the dentist!

Dental Associates Patient February 19, 2013
Always explains things well & listens to your concerns.

Dental Associates Patient February 07, 2013
Dr. Hahn is very thorough and always explains the procedures and answers any questions. He is very personable and comes across as extremely knowledgeable and efficient.

Dental Associates Patient January 14, 2013
I usually do not see the orthodontist unless I request to talk to him, but when I do talk to him he is always very polite & understanding.

Dental Associates Patient December 21, 2012
Appreciated Dr. Han talking on the phone to us twice about our concerns.
