Dr. Chan is a wonderful acupuncturist with 56 years of experience and is the only one who has been able to offer help to my 9-yr suffering from debilitating headaches and abdominal pain. After a year of going through all the Western medicine had to offer with no effect, our dentist of all people recommended Dr. Chan. And the effect has been almost instantaneous. The reduction in pain level and the number of occurrences has gone down by at least 60% and my 9-yr old is like a new kid. There were visits where pain level was at an 8 (out of 10) at the beginning of treatment and Dr. Chan would bring it down to a 2 or even a 0 in the span of a 20 min session.Highly recommend Dr. Chan to parents who are at their wits end trying to get help for their child suffering from headaches. The only catch is he will only perform acupuncture on kids who tolerate the needles.
