    Dr. Zaman was very nice and professional he had clearly made note of the records that had been sent to him and discussed those records with me and very knowledgeable and satisfactory matter. The procedure went smoothly and that was the end of our interaction.

  • Jun 20, 2019

    He was caring and communicative. He had studied my chart and accordingly adjusted the use of equipment used for the procedure to my specific needs. I feel wonderfully normal this morning and the only aftereffect yesterday was the need to sleep off the effects of the sedation.

    Dr. Atif was extremely professional, attentive and efficient. He came out to follow up when I had post-procedure reaction to the sedative. (I would have liked to know that 1 in 10 patients have a reaction to the sedative beforehand though as I would have waited longer in the hospital instead of leaving and having to return. Dr. Atif then did prescribe an anti nausea tablet (which I later threw up) but as I had been discharged we had to collect the prescription separately.) I would certainly recommend Dr. Atif.
