I recently when to see Dr Helen for a tooth extraction + implant (and a bone graft inbetween). Beyond the technical side and the great job she's doing, she's extremely, caring, considerate, and patient, always explaining all the procedures and options in details, the pros and cons of any solutions (including costs), really leaving in the end the choice in your hands. She's also always available to patiently answer any questions you may have and relieve you of any apprehension.
And her staff is as friendly and professional as her.
I highly recommend Dr Helen.
