Hes been my primary for years and he has been wonderful. Dr. Ko saved my life. Cannot thank him enough.

This Dr is the master of Pulmonologist. Awesome.

Dr Ko diagnosed me with COPD 2 years on oxygen and the wrong medication. I went to Keck they tested me after changing me to the right medication and found no COPD no more oxygen I feel great. Dr Ko has no idea what he is doing. He also gave me a diabetes medication i asked if he had any problems with it as it is a new medication he said no. It left me laying on the bathroom floor in pain for hours, i told him about it and he gave me the same drug under a different name. I did not take it, I am not that stupid. I cant say enough about the damage he has done to my health.

Doctor Young J. Ko, M.D I knew him for a little bit. Hes the best Lung Specialist, ever.
