Kern Koo, DO

Dr. Koo is a ok doctor but his receptionist’s Helen has no respect and very rude I would never go there again. Who in the right mind would give his which a job… Oh wait they must be related.

Receptionist is legit crazy and rude.
Liked the Dr at first. Went in because my boyfriend has been experiencing stomach pains over the course of a year that was just getting worse. Dr. Koo reccomended we have a sonogram done. We did that. Over a month passes and the Dr never called us about the results, we assumed everything was fine. Until he had another episode which was worse than all the others, I had to rush him to the emgency room. Went to LIJ. They did an xray and gave him pain meds and said it must be an ulscer, sent us home. We followed up at Dr. Koo’s office the very next day. DR. KOO THEN FOR THE FIRST TIME OPENED THE RESULTS FROM THE SONO HE DID OVER A MONTH AGO AND SAID «OH YOU HAVE A GALLSTONE»
My boyfriend had to go back to the hospital and have surgery to remove his gallbladder.
When I asked the receptionist why we never received a phone call to go over his sono results her answer was «I have been very busy and behind.»
UNACCEPTABLE.

Doctor Koo is the bomb dot com. He’s my hands down absolute favorite doctor. Very funny, caring and attentive! Hes always is available to answer any of my questions and my family has gone to him for years! The receptionistts are great and the overall atmosphere is amazing! Doctor Koo comes highly recommended!

The M… Family has been going to Dr Koo for many years. He is always on point with his diagnosis. Very well run office, wait time is very short. Doc is great!!! Thanks for serving our community. Thanks again Victor M.

I am quite skeptical when it comes to the quality of doctors who focus on internal medicine, especially since I’ve had two bad experiences due to inaccurate billing codes and dishonest billing (one being a doctor who I still have respect for and one being Dr. Ronald Fagan). Usually problems don’t arise in doctors offices until insurance gets into the picture. Nonetheless, my first visit with Dr. Koo was generally good.
Dr. Koo personally practices the usual procedures for a check-​up (weight, height, blood pressure, eyes, nostrils, ears, mouth, lungs, pulse rate). He checks your pulse rate by placing two fingers over your wrist, a traditional pulse diagnosis. But what amazed me most was his skill with the needle, possibly comparable to an awesome nurse who used to take my blood when I was still with my loving pediatrician, Dr. Katherine Zeng (best pediatrician hands down!). I have yet to confirm his needle skills after my next annual physical. Anyway, a week after my visit, Dr. Koo followed up with me via a brief phone call regarding my blood test results. Overall? So far so good!

Hands down, he is the best doctor ever. Not only does he have exquisite attentiveness and wisdom, but Dr. Koo goes out of his way to make sure that he and his patients have a caring relationship. He always gives me advice on basically everything and is so generous towards his patients. It is no surprise to me that patients absolutely respect this man.

Still one of the best Family doctors around!
Not certain why G.L. is giving such a bad review, but judging by the lack of reviews, and friends and no photo, you can dismiss it.

Dr. Koo must have something against me. I don’t understand how other people had such great experiences with him. He is incredibly rude and impatient.
