Dr. Zakashansky is a phenomenal doctor! I was thoroughly impressed with his bedside manner. He was calm and kind about everything. He even called me the day after surgery. Almost to the point I was worried when I heard his voice. Ha! But he was simply just checking up in me. Awesome awesome attentive doctor. And I felt ZERO pain day after. I’m on day 5 and no pain-just discomfort (from laparoscopic air but that’s it)! Highly recommend!!
