    I have been seeing doctors at Hopkins for about 12 years for frontal fibrosis alopecia. Other doctors did not believe me when I told them I was losing my hair. Doctors at Hopkins believed me from the beginning and have been kind and very supportive. Dr Aguh could not be any nicer, listens to what I have to say, explains new theories about my condition, and I feel she has my best interests at heart. I feel very privileged to have had wonderful doctors since the beginning of my treatments, and Dr. Aguh is definitely one of my favorites.

    I absolutely LOVE Dr Aguh. SHE SAVED MY LIFE!!! She identified a tiny spot on my leg, which I had not even noticed. It was a rare melanoma and according to my surgeon, it would not have been unreasonable to have missed it or not biopsied it. Due to Dr Aguh's comprehensive examination and subsequent biopsy, my cancer was caught at stage one, saving me from complications and saving my life. My family and I are deeply grateful and indebted to Dr Aguh!
