So glad I have this Doctor to oversee my health needs.
Excellent doctor
Dr. Nishioka had read my history of problematic ulcers, asked more probing questions and took time w/me to figure out the treatment in order to prevent another episode. He was kind, thoughtful and clearly knowledgeable.
The Dr was great! He was patient & answered all my questions! I never felt hurried. I would recommend him to family & friends! I feel very fortunate to have him as my Dr!

He's very smart and I wish he was my PCP actually, but I know he can't be. But he's just a wonderful doctor all around and I would send anybody to see him. He's just wonderful. I just wanted to let you know ... Read More
