Poor communication between sites wasted too much of my time driving to alternate site cost me over an hour to get a simple blood test and another 30 minutes to get out because they couldnt read my parking ticket Very rude parking attendants Even thw security guard tried to help and they were just as rude to him.

Katherine Ishihara is a wonderful example of what a heath care provider should be. She is kind, knowledgeable, and actually listens to her patients concerns. I went in feeling like once again, I wouldn't get the answers I've been seeking for 12 years just like every other Dr visit, however this time that was not the case. She addressed my concerns with compassion and understanding and finally ordered the blood work I've been asking of every health care provider I've seen for many many years who wouldn't order it. I finally got my diagnosis and can be on my way to finding a way to manage my pain and symptoms. Katherine will now be my primary care physician and I'm so appreciative of her. Thank you so much Katherine!

Katherine is hands down amazing! As a female, physicals are never fun, but she guided my through everything she was going to do. She also gave me pointers to make my pap a lot more bearable. I have never walked out of the drs office feeling so positive, informed and happy. Also, I've had a tough past and she made me feel so comfortable about talking about it. Just knowing she wasn't going to judge and she only wanted to help made it easier to open up. It was amazing! I would recommend her to anyone. I'm so happy I got to visit her. Thank you, Katherine ! You're so best. Keep doing what you're doing.

She's amazing and sweet and always made sure I felt comfortable the entire visit and never rushed an answer. She kept the possible diagnosis open to really understand what was happen rather than writing me off. She allowed for me to feel like she really cared about my health.
