First of all, I have to let you all know that my review may be biased for I am Dr. Fu's brother in law.
From childhood on, Dr. Fu was known to be good with his hands working on tiny objects. So, I understand that his elder brother suggested him to pursue dentistry. And Dr. Fu did well to heed to his brother's advice.
Dr. Fu, as far as I know, has kept himself up to date as to dental technologies.
In my opnion the reason why his clients keep coming back to him is because of his mild personality that can put any anxious heart at ease with his simple smiles.
