 |  Very painful biopsy  |  show details
Mar 29th, 2013

Dr Loo seemed like a professional doctor but who does a biopsy without any anesthesia??? Dr Loo claimed there would be no pain just discomfort. I was a skeptic but trusted him. It was a very painful procedure. Afterwards, I googled the procedure and every site stated local anesthesia is used for procedure. I even asked others who had the procedure done by other doctors and they said anesthesia was used. Dr Loo is sadistic. How dare he perform biopsies without any anesthesia. Looking at other reviews I saw another person also commented on this. Wish I read reviews earlier. Find another doctor that uses anesthesia.

Was refered to Dr.Marcus Loo from my friend. Had a bad prostate infection and called the office and was seen that same day. Found the office staff pleasant to deal with. THe waiting room and exam room were very clean. When I saw Dr. Loo he was very interested in what I had to say and spent time answering my questions . A top notch doctor that would recomend to others

Dr Loo has a friendly, helpful staff. I had a kidney stone which was treated without surgery. The care I received was excellent. There can be a wait to see Dr Loo.

Way overbooked the slots. Waited 75 minutes after appointment time. Asked how much longer, 30 more minutes with at least 10 patients in the office. So don't bother unless you have more than 2 hours free.

Was done without local anesthesia, and itwas roughly done, excruciatingly painful.I cried out loudly many times.Doctor's demeanor was dismissive, curt throughout.

I was impressed by the bilingual staff. They were very helpful. Dr. Loo took time to talk to me and we discussed my problem and the treatment he has recommended. He is a caring and thoughtful person.

This doctor has no patience and does not like to be interrupted. He has a very bad attitude. One office visit and he charges alot of money for 15 minutes. All he cares about is money.
