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.

This office is an absolute disaster. As a patient with UC I have never encountered a doctor who…read morehas refused to fill out a jury duty excuse for a patient with a legitimate medical history. This office put me through the ringer of stress and BS when I called requesting helping from a physician who I presumed knew enough about UC to know that jury duty is an unequivocal nonstarter. I have been trying for 2 years to get copies of my records in order to transfer my care properly and to date have gotten no help. Emails no longer go through, so today I resorted to leaving another voicemail. Lets see if anyone has the integrity to return my call.

Do not go to this doctor! It is impossible to pay your bill on the portal and the billing…read moredepartment will ignore your calls and put you in collections. I owe $36 and have called three separate times with no call back. The portal has you enter your statement code, then your credit card info, then takes you right back to the welcome page and asks for your statement code again. Why have a billing department if they never answer their phone? I am going to report them for putting me in collections. Update: After spending over an hour on the phone with this offices medical records dept and then my insurance, someone claiming to be from billing finally called me back. After I explained to her several times that I had been on the phone with their medical records dept and my insurance trying to resolve this after her dept failed to return my call several time over the last months, she continued to say "I thought you said nobody has called you back." She also claimed that I owed additional money. I tried to give her my credit card number but she was driving or something. She finally hung up on me. I then called the offices appointment line and they said I do not owed them the original $36. The billing person lied to me! It should not be this hard to handle a bill.

Dr doctor is holding my antacid medication as hostage because due to the pandemic he is not making any money and he told me on the last visit to wait 10 years to come see him and it has only been 7 years. So after talking my primary doctor he went ahead and filled my medications and said that this was not the rite for this doctor's office not filling my medication. At this point I will find a new doctor and not come see this doctor again. He is not the only doctor in town. I do not and would not recommend this doctor.

I came in and Johana checked me in. I was missing some questions on forms and that got squared away along with my insurance card.

We figured out it was still the appropriate venue to schedule a procedure. He then recommended a primary care physician. All in all, professional from the moment I walked in, checking in and meeting with Dr. Snyder.

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.
