Went in for a major issue from an ultrasound, he completely ignored it and scheduled a scope down my throat. When I woke up from anasthesia, room full of people (intern nurses?) it was a big joke, "Oh, he's awake, ha ha ha!" So after that, I expected a follow up re: results of that procedure and to address the primary issue for which my PCP sent me to a Gastro, nada. Not a word. I don't know what else to say. Horrible.

First visit 1 month ago the lady that answered the phone put me on hold 5 times very rude she told me they were short handed then i ask for an appt they put me in with a Dr Kniaz who I did't ask for I ask for Dr Nallapareddy they said he was booked I saw this Doctor and what a rude Ingnornant person he was. The staff was rude, nursing was rude and I wanted to ask a question about the colonoscopy they told me to go talk to the scheduler she had no clue what she was doing either I cx everything.

Terrible Doctor. When I woke up from my colonoscopy he said "it's just IBS. Eat more fiber." Then he walked out. After he left, I told the nurse that eating more fiber upsets my stomach, so she told me I shouldn't. He didn't even suggest further testing or meds and instead told me to take Benefiber which did nothing. I could tell he didn't take me seriously. I had to suffer for another two years until I switched to a doctor that actually took my concerns seriously.

Dr. Kniaz will take whatever time his patient requires to answer all questions and really cares about his patients. He's on his 3rd generation of patients in my family.

He is the worst doctor i have ever seen I would not have a dead dog see him. The office staff is rude and the medical asisstants are dumb they ask me questions then a nurse ask me the same and said nothing was charted from the asisstant . The office is a filthy place, no tv for my son to warch while i was being seem by this rude doctor.. I would never recommend any of these doctors to anyone.

Worst doctor ever! I had h pylori and I went to see him in July and he kept sending me away saying I was just probably stressed or it was my diet.I got so sick and ended up loosing 30lbs.I finally demanded a endoscopy and they saw h pylori,gastritis and gerd! I was sick for 6 months before he would take me serious!I now have a lump on my right side and I've asked him to check it out and he completely ignored me! Will never step a foot in his office again! Also plan on waiting 2 hours to be seen!
