Carson, CA |
Do not see Dr. Zaidel as often. I see his PA who is very personable and caring. The only negative experience has been with the newer Medical Assistance and the the Lab Assistance. They are friendly when Dr or PA are present, but have a different attitude when Dr. and PA are not present.

My experience from my first colonoscopy through today is excellent on all counts. He has a very friendly, positive attitude. He listens carefully to my symptoms & complaints. He carefully considers recommendations for care from conservative to aggressive. I liked the approach and the solution to my problems that today are resolved &/or manageable. I'll see him again in 3 years for a repeat colonoscopy due to my family history.

I would recommend Dr. Zaidel to anyone. I loved his predecessor who retired and feel the same about him. He is knowledgeable, caring, and really stays on top of your issues.
Woodland Hills, CA |
Horrible bedside manner.
Manhattan Beach, CA |
The office staff is so poor and cause of so much stress that it is not worth it to wait for Dr. Zaidel, who is otherwise very good. Dr. Zaidel admits that stress is a cause of a lot of gastrointestinal disease, and the office staff admits that elevated blood pressure is a consequence of patient stress as a consequence of the extremely long wait times. That, frankly, is a violation of the Hippocratic Oath, the essence of which is "first do no harm." Well then, harm happens in this office.

Friendly and good communicator. Takes time to explain things. I really enjoyed my experience with him.

Dr Zaidel will not give up until he founds out what the cause of your illness is!
