Dr Zhang is very knowledgeable. She diagnosed me with high blood pressure and hyper tension on my first visit. It was my first time being told this. I was feeling stressed out and had neck pains that was acting up. I visited my physician and he told me that my blood pressure was up and that it wasn't that high on my past visit. He prescribed me with blood pressure medication and will evaluate my blood. I've completed my 3rd visit at Legacy Oriental Medicine and feel a lot better. I've adjusted my diet which includes: drastic reduction of caffeine intake, no alcohol, reduce salt intake, reduce red meat, and reduced pre-workout supplements before I work out. I feel much more relaxed and will continue treatments. I started treatments because of neck and shoulder pain.
