Spokane, WA |
worst dr. their ever was doesn't listen waited 2hr's to see. 3 patients scheduled at the same time. staff very slow and stupid. talk about their personal life while you stand their . outrageous!!!!!!!!!!!!!!!!!!!

Dr Sienko was assigned my mom's case for ITP recently when she was admitted to the emergency room. His bedside manner was very rude and short. Seemed like he was in a hurry to leave and discredited all questions I had concerning my mother. He did not want to take any responsibility on questions about her treatment. Using terms like "they", who is they? I would not recommend using this Dr in the future.

Very personable. Explains complicated issues in simple terms. Takes the necessary time needed to make sure we understand what's important so we can make informed decisions.
in Spokane, WA |
Dr. Sienko was my mother's Dr. When she was first diagnosed with a rare cancer. This Dr. Had a very poor bedside manner, he left us waiting at almost every visit and clearly had not reviewed her case until right before seeing her. He was rude, impatient with her questions, and discredited what she would say she was feeling. After changing Dr.s we found he misdiagnosed several things. I would not recommend him to any cancer patient. We wasted valuable time with him.
