Dr. Kostenboym was very attentive and looked me in the eye. I was nervous whether I made the right choice to see him and I left feeling very confident that I chose a Dr. that I would feel comfortable calling on with my health issues from this point on. I would recommend him to women as well as to men. He is very friendly and I had no problem at all understanding him and he had no problem understanding me. I appreciated being able to have my blood tests done right there in the office and his nurse is very sweet and gentle. One more plus is that the Santa Monica office is very clean and just so pleasant to look at.
