We have had Dr. Marc Iwahashi as our family doctor for the last many years. His diagnose is on the dot and accurate. I highly recommend him as family doctor.

Really nice and on the ball. I would go to him again for sure.

He's sympathetic to his patients and is very knowledegable.

AWESOME DOCTOR!! I wish I went to him directly instead of going to ER first for my allergy outbreak. Dr Marc Iwahashi is very knowledgeable, patient, understanding, treat you personally instead of putting you like assembly line. In less than 5 minutes he knew my illness already and prescribed the correct medications. And he gave me BONUS advice on how to keep myself healthy, suggests a good reading on personal health, and give "make sense" advice that is doable in daily lives. As a result, I have lost 16 pounds from the last time I saw him.

Dr. Iwahashi was nice. I went to him for a second opinion... and he definitely asked more questions than my first doctor.

Very pleasant and caring doctor. His diagnosis is incredibly "right on the money"! Also, he does not believe in unnecessarily prescribing medications. Typically recommends alternatives to popping pills (Ex. for back pain, exercises instead of a pain killer).

speaks japanese and cares for many expatriates in silicon valley
