Dr. Checkmadian (phonetic sp.) was thoroughly familiar with my chart, went over and explained my lab results in great detail, I was ver pleased with his care. Dr. Otsu answered my questions and thoroughly explained next steps In case of allergy episodes. It was a second opinion appointment. They verified and agreed with Dr. Patel and had no specific follow up in my case.

Dr Otsu answered my questions extremely well. I left feeling that I had more information about my lung disease. Dr Otsu always seems to understand my concerns and is both truthful and encouraging. I like seeing her very much, and I feel very fortunate to have such outstanding care.
