I'm a fan. Dr. Nickowitz deserves the praise and loyalty he has amassed over his years of service in Pasadena. He consistently demonstrates solid judgement in treatment of GI health. He's always 100 percent present in our office visits, a quick learner, and careful in taking action steps. Unconditionally recommended.

I have been a patient of Dr. Nickowitz for 10+ years. He is the same outstanding doctor today as he was when I went for my first visit. He is a good listener, knowledgeable, thorough, insightful and has a calm presence. He also explains why he is making the decisions and recommendations he makes. He could (and should) teach a master class in being a first-class doctor. I appreciate his shaking hands with you when he greets you and guiding you to the area to make appointments for necessary procedures when the appointment is done. Thank you Dr. Nickowitz!
