Dr. Nickowitz is a caring Physician who is one of the best Doctors in his field. His approach is warm and caring , letting the patient talk about their issues, then asking questions. I have been seeing him off and on for at least 15 years. He is a problem solver, and a listener. He explains your condition in simple, understandable terms.

in Sierra Madre, CA |
My appointments with Dr. Nickowitz are accomplished very professionally, but always in a manner that is understandable to the layman. He is willing to spend the time necessary to make sure I don't leave with unanswered questions and concerns.
in Claremont, CA |
As Dr Nickowitz was referred by my doctor, I attempted to make the initial appt and left two separate messages but called 5 times to schedule my procedure (the receptionist never pick up, only a recordered message by "Dan") asking for a call back. No call back, I'm glad it was not an emergency. I'm taking this as a sign for me to go to another doctor.
in Monrovia, CA |
Dr. Nickowitz is very knowledgeable and has a calm and reassuring demeanor. His staff was amazing when setting up my hospital exam appointment and clearly and patiently explained everything that I would need to do to prepare for the test. He is very busy, so it may be a few weeks before you can get in to see him unless it is an emergency, but he is worth the wait.
