Been trying to make an appointment, cannot get anyone on the phone…read more Called a week and a half ago, held for a long time, was dumped into voicemail, left message requesting a callback for an appointment--NO CALLBACK. Called this morning, held for about 8 minutes, then got a message that voicemail is full and to callback later--THEN I WAS HUNG UP ON. This office is run terribly. Very unprofessional and low service standards. I left several messages requesting a callback from the office manager some time ago--SHE NEVER CALLED ME BACK EITHER.

He is the definition of a remarkable human being and a gentleman. And one who defines medicine. His Nurse practitioner in the Glendora office is a terrific representation of him. She is hands on and a "people person". The way she treats you is therapeutical.. It helps you to forget that you even had a problem while you were there. There are others' who calls themselves doctors and NP out there, who can take a page from their books to improve themselves as human beings and who they claim to be in their profession. Dr Mourani is effective, competent, knowledgeable and thorough, because he his is operating within his God given gift, and not to identify with prestige or profit. Even though one has to work to earn their living, he is well deserving of his , he earns it everyday. He is a part of the few doctors on earth who are the very best. There are some out there who calls themselves doctors and they should be plumbers. they were never mean to be doctors, so they have no clue as to what they are doing. Thank God for Dr. Mourani

I recently went to see Dr. Yoo for a colonoscopy. I found him through my insurance company website…read moreand saw that he was located nearby in Rowland Heights. When I called to make my appointment, I found out that Dr. Yoo moved his practice to a new building in Diamond Bar as of March 2024. Dr. Yoo's new office is located in the newly renovated Diamond Bar Medical Plaza, which was previously a Chuck E. Cheese (if you all were in the area when that was around). Looks like they are still in construction, as a couple offices are still vacant with plastic on the glass windows. The staff I encountered all very friendly and nice. Dr. Yoo was professional and clearly explained the process and indicated what I needed to do to prep for my procedure. I came in on a Monday and the front staff was able to fit me into an appointment on Thursday due to a last minute cancellation. This kind of procedure is not fun, but the entire staff made me feel comfortable the entire time, and the nurse who attended to me was so nice, I felt like my mom was taking care of me. =) She made sure I had extra blankets because I was cold and came by a couple times to made sure my IV was ok. I got a call the day after to follow up and see how I was feeling and if I was experiencing any issues. I appreciate the check in even though I was feeling good! I highly recommend Dr. Yoo if you need an gastroenterologist.
