1st rate Doctor, easy easy colonoscopy! Office was great, Surgery Center was amazing. First time I wasn't scared!

I don't understand how there's anything negative about this doctor. since 2020 I was having so many health issues. Specifically my stomach(so I thought??) and I've had so many hospital trips. No one not one dr could help me figure out why I felt so sick. I finally got admitted in July 2025 and met dr Darsani and he prescribed me a medication that worked within one night... and literally changed my life. Thank you Dr Darsani. read more

So very blessed by Dr Al-Darsani - he is knowledgable, compassionate and makes your procedure as easy as possible! Was so frightened to have this done and he allayed my fears by being calm and caring...I really appreciate him!! read more

This review is more for his office staff than for him. They do not return phone calls. EVER. I left four voice mails trying to schedule my colonoscopy and it finally took me going to his office in person to get a human being to assist me. Through the window I could see three women behind the reception area but they all pretended I wasn't there. I knocked on his office door-which was locked-and none budged. I finally went downstairs to the pharmacy and asked for a paper, pen and tape to leave a note to implore his office to call me. That finally got a reaction. Now, a month after my procedure, I still don't know the results of a biopsy. Same scenario-calling, leaving messages that don't get returned. Very disappointing! read more

Worst doctor's office that we have never been to -- they moved to a new office without letting the insurance group know, and they should probably advise the patients when taking appointments because they just moved recently - We went to the old address which is listed on the referral letter and was advised they had moved to another location. The attitude for the 2 receptions is very bad. NO "Hi", NO "Hello" and NO smile. All she said is "we don't take this insurance anymore" even though I have the approval letter from the insurance company on my hand. Besides, shouldn't they ask or check the insurance info when they made the appointment? I specifically asked if they need the reference number on my approval letter, they said "NO"! As such, we spent the whole afternoon just for the above, and got nothing done. read more

Dr. Darsani Is the best! His employees are super great people,very friendly and make you feel welcomed. I have been going to him for years and always seem to come out feeling happy,even when I am sick. Once again I don't have enough to say about him and his staff but Thanks for being so nice and wonderful! Steve read more

My husband had services with Dr. Darsani. He's always giving him great advice as to go about better healthcare for his condition. Today, my husband had to go to the ER on a Saturday. I wasn't too pleased with what the docs at the hospital were advising and planning to do. So I called Dr. Darsani's office. I got the exchange and they contacted the doctor. Within 5 mins, Dr. Darsani called me. I explained my situation and he called the hospital and told them what to do for his patient. As of now, they updated his medicine and changed pain meds. He's currently in a better state and you bet they're going to make sure he's taken care of. Without Dr. Darsani, my husband would have been sent home, not knowing what could have gone wrong. Feeling grateful. read more

I am an older American who contracted Hep.C in my youth. The hideous disease sat dormant in my system until I reached 50 years of age. After failed attempts with Interferon and ribavirin. A few years ago my Liver was down to 10% functionality. Dr. Al-Darsani prescribed Epclusa, a direct acting agent. With little side effects it cleared my Liver in 90 days. Dr. Al-Darsani, with the help of Epclusa Saved my Life. read more

So I got a response from the "professional" it turns out he is not taking responsibility for anything. I will add a picture of the private message he sent because, of course, he wouldn't respond in public. As a business owner the one thing I avoid at all cost is arrogance. It makes people further angry but the worst are people who try to blame their mistakes on their customers and actually believe they will get away with it by hinting that you as a customer are plain stupid. Do not I repeat do not go to this place. Check the other reviews. Not the only one. read more

Al-Darsani Hussain, MD - Internal Medicine Near Me - Chino, California

Beware! This is the most disorganized doctor's office that I have visited. Dr. Al-Darsani wrote the wrong appointment date on my instruction slip for which I asked his office staff to correct. Moreover, during my "private" consultation with the Doctor, he took a personal call on his cell and discussed his personal matter with the caller as though I was not in the room. The worst part of my association with this doctor and Chino Premier Surgery Center is that they don't know how to read a negative COVID test! A Rapid COVID test was performed on me the day of the scheduled procedure. According to the Acuvue instructions, my test was negative. The young lady that tested me indicated that she didn't know how to read my results and would confer with Dr. Al Darsani. He canceled my appointment immediately preceding the procedure! Although, my test was negative according to the written instructions. I lost time, money and sleep preparing for the scheduled procedure. I have other instances of the disorganization that I experienced, but I don't want this post to be any lengthier. Please, for your own sakes, choose another doctor. I made this post because I don't want other patients to experience what I did. read more

I want to give this Dr. 0, that is zero stars, but I can't. This review is based on my experience. To make a long story short, I had a colonoscopy done back in February of 2016, and had a post-op appointment that I couldn't make. You would think that these folks would follow up with their patient - NOPE! Not one follow up call, not even a "hey we have results that we'd like to share with you". After noticing they wouldn't bother to call me, I decided to not contact them due to the fact that from the beginning I was treated as a number. Every single time I spoke with him, I felt like he was talking to me with the purpose of getting me to the colonoscopy table. I'm sure I was just another number - colonoscopy's must pay well these days because after I had mine done, no follow up was intended. So, at this point, I have no idea if I have diverticulitis or not, or if he found something else. And to make matters worse, I continue to have the same pain that led me to have a check up the first time. I'd suggest if you live near or around the IE, that you find another gastroenterologist. This one, based on my experience will see you as $$$ and not really show that they care. read more

I've gone to this doctor before because my PCP refers me to him. Every time I've been there, I've waited over an hour to be seen. This is ridiculous. When I asked the front desk how much longer til I'll be seen, she gave me a snotty response "you're next". That "next" was still another 15mins to sit in a room because there was still another person in front of me. I asked to be rescheduled. Front desk offered me Friday, knowingly there was an open appt tomorrow(Wednesday). I've already called my PCP to refer me to someone else. read more

don't even think about going back to this place,I was referred by my primary physician to see Dr. Darsani but he didn't do anything,just told me to do colonoscopy and was offered that they have their own financing,al though I have my health insurance,just in case insurance won't cover the other cost which is around 900+ anyways, I was charged for that visit/consultation for 275.00....seriously???? It's better to google my symptoms and get better answer than talking to him. read more

The worst doctor ever you can see....i was refered to him by my pcp. He didnt check ne at all and ordered an endoscopy. I had and the endoscopy and never got back from him about the results. I called the office for an appointment and they scheduled me for an app in 2 MONTHS. When i went there he started to check his laptop as if never have seen me be4. He firgot about the endoscopy. I told him that i m still suffering and he found out that i ve h pylori...which is causing cancer if not treated at once....he gave me a treatment for 2 weeks...and i did the breath test and it was negative...i went for an appointment again and he said u r fine even though i told him i am still suffering...i cant imagine that doctors like those exist in the US.....never go there. read more
