Dr Yip is the best doctor I have ever met. He is kind, caring and gentle. I would never go see another doctor. I have felt fatique, tired, lack of energy and hair loss for over 1 year. I have seen several other doctors and they said I have underactive thyroid. They put me on thyroid medication and my condition did not improve. I finally see Dr. Yip who diagnosed me with a rare condition called Addison's disease and started on treatment. I feel like a different person!! Thank you.
