Dr Nickowitz is the best doctor I have ever had in my 60 years of life. He is genuinely interested in all of his patients and wonderfully thorough in his review of your test results and treatment plans. The best.

I am so glad I'm in the care of Dr. Nickowitz and have him perform my colonoscopy. He went over everything, and practically memorized my chart. He took the time to answer any questions and just was the best.
