Real Patient Reviews

I have been going to this practice for several years now. I seemingly never have to wait when I arrive at the office and they are all very professional. Dr. Hartlieb and Dr. Ching have been terrific. In addition to doing great dental work, each has a great rapport with their patients. All of their assistants have been top notch as well.

I recently met with Dr. Ching to have some dental work done, and had an exceptional experience at this office! I usually hate going to the dentist, but this experience was different–this office is hands-down, THE nicest dental facilitiy I have ever seen.

- Shaun F.

This dental office is something I haven’t seen before. I had many past dental experiences at other dental offices (unfortunately not good) and finally I found Chicago Beautiful Smiles. Dr. Hartlieb had helped me restore my teeth to a beautiful smile.

- Natasa R.

I am a loyal patient for over (yikes!) 20 years because I appreciate the time, skill and patience of the entire team. As proof of my gratitude, I live in the city and reverse commute every six months for my appointment.

- Dennis H.

Dr. Hartlieb is by far the best dentist I have ever been to. He has transformed my smile into something of beauty. In fact, many people comment on how beautiful my teeth are who do not even know that I have had major dental work performed. I used to never want to smile that large before, but now I smile as big as possible when photographed.

- Fran L.

I always have a great experience when I go to Chicago Beautiful Smiles. The staff is amazing and Dr. Hartlieb and Dr. Ching are extremely knowledgeable and friendly. The facility is incredible and I feel like I’m being treated with the best technology in the dental industry. Go to Chicago Beautiful Smiles for a consultation and I guarantee you will go back time and time again. It does not get any better in the Chicago area.

- Antonio S.

I had a great experience with Dr. Ching – very professional and thorough in his craft. I had been seeing my previous dentist for the past 15 years; however, I am ready to make the permanent switch to Chicago Beautiful Smiles. Dr. Ching is great at explaining the procedures he was performing and made my visit comfortable.
