Dr Koh is very good and spends the time necessary to discuss patient's condition, treatment and most importantly does not make you feel rushed. Very knowledgeable in his field and I rate him highly.

The ultrasound technician at 1775 Ballard was unpleasant. She barked 2 word orders, was generally uncommunicative and somewhat rough with the procedure. None of this was expected or necessary. I will probably go elsewhere next year. Dr. Koh, on the other hand, is fantastic, very calm and not rushed, explains everything well, engendering confidence. Excellent physician.

Dr Koh has an excellent professional manner. I always feel very comfortable during the visits.

Dr. Koh and the staff are excellent! They are warm, caring, & professional! I've recently lost 50 lbs since my last visit and the nurse co granulated me on my hard work- it felt good! Dr. Koh explained things and was thrilled at how good my numbers looked. They are wonderful!

Dr. Koh is best.

Very informative and helpful.

He is a great doctor and a kind man?

Dr. Koh is an excellent doctor. I feel very fortunate to have him as one of my doctors. He is personable and extremely knowledgeable. He explains his decisions related to my care in an easily to understand manner. He also took me early to my appointment time.

Excellent Experience!

Dr Koh is the best. He caught an abnormality that multiple other doctors did not find that was impacting my heart and causing me to go to the ER multiple times. Thank you Dr Koh!
