I had a crown lengthening procedure done with Dr. Oh. She is very professional and thorough with explaining what is going to happen before, during, and after she is done. I never felt rushed or uncomfortable in her office. The staff is amazing and does an excellent job at making you feel relaxed. Brenda, the receptionist, will go above and beyond to help you with scheduling, billing, etc. I highly recommend this office if you need to see a periodontist.
