    I have been dealing with a health issue for over 2.5 years, my last Johns Hopkins Endocrinologist did not help me, multiple doctors did not know what was wrong with me. This doctor knew exactly what was wrong and was able to adjust my meds and I immediately felt better. I had a great experience with him. I have nothing bad to say at all.
