I originally came here for a tooth implant. Dr. Hsieh was able to offer InvisAlign treatment option prior to tooth implant. I am very happy with my new tooth as well as the continual cleanings and routine x-rays.

Excellent work from Lotus orthodontics! I was quiet nervous to have an implant placed as It was my first time having any kind of oral surgery other than having a tooth pulled. Dr Frank is a very experienced and conscientious periodontist and I felt no pain or discomfort. He even contacted me personally the next day to make sure there were no complications. Very happy to have all my teeth again!

Very friendly and gentle. I went in absolutely terrified in the beginning and they went out of thier way to make me feel relaxed and comfortable. My gums have improved enormously thanks to Dr Hsieh and I will never go to any other periodontist!
