And when I came in for my appointment, I felt very welcomed. Nurse Angela was so sweet and very informative. After leaving the office, I understood exactly what I was going to be doing before my colonoscopy. That information helped relieve a lot of stress I was having about getting a colonoscopy. I was surprised How easy the whole process was. I have been putting this off for over four years. Thank you, Dr. Nouh at Optum for recommending this office, as I would not have known about them on my own.

This review is for Dr. Mankal who works out of the same office. My elderly father was diagnosed…read morewith advanced Liver issues after he contracted Covid 19 in 2020. The liver doctor at hospital gave him a year to live. After he was released we were traveling to a doctor in San Gabriel which was quite a distance since my parents live in Lakewood, Ca. After searching the internet I came across Dr. Mankal in Los Alamitos and when I say he has been an absolute God send, I mean it!!!! While my father's condition is not without its issues, Dr. Mankal has been amazing. His bedside manner is incredible, he is patient and extremely knowledgeable and best of all my father is still with us, 4 years after the liver doctor at the hospital wrote him off. I also love the portal and usually get answers to questions or requests for meds within 24 hours. I hesitate to post this review because I worry Dr. Mankal will be swamped with new patients but then I think of others facing these types of challenges and needing quality care and feel compelled to share. We also love Angela, his front office lady, she is wonderful as well! I strongly recommend Dr, Mankal and Angela!!!!!

I am so shocked to see negative reviews about Dr. Hertz! I have been a patient of hers for several…read moreyears. I can't begin to explain how grateful I am to have her as my GI Doc. I have had a couple procedures with Dr.Hertz. All went extremely well! She is very professional, very caring, very knowledgeable, and amazing bedside manners! She has treated me for various reason and has always been very accommodating to me when I need to get in urgently. I am extremely grateful for her because without her I probably wouldn't have had a wedding when I did. I fell very ill to the point I could not eat or go about my normal routine. I was so sick I had lost a lot of weight and was always in extreme pain. This was a month before my wedding. Dr. Hertz went above and beyond! She got me in, spent so much time with me both in office, and out of office hours. She made sure I was taken care of. She recommended a colonoscopy and endoscopy the week of my wedding. I was very worried about having a colo since this was my first one and honestly just didn't want to have one. Dr. Hertz assured me and was very patient with me. The Day of procedure came, and everything went extremely well. She prescribed me medication and because of that procedure, she removed a big precancerous adenoma! Who would've thought! When I say she cares, I mean she truly cares! Day of my wedding came. I felt a little better being on meds but still a little discomfort. She spoke to my fiancé early that day before our ceremony and he told her how I was feeling. Kid you not, Dr.Hertz called in a prescription to the pharmacy and picked it up her self and brought it to me!! Thanks to that I was able to eat and enjoy my wedding and honeymoon. I am so grateful to have her as my doctor. I would recommend Dr.Hertz in a heartbeat. If I could give her more than 5 stars I would!!

I…read moreabsolutely *love* Dr. Trivedi, who also works at this office, and I've asked to become his patient twice over the past five years. I had the chance to see Dr. Trivedi once when Dr. H was unavailable, and I was so impressed by his bedside manner that I requested to switch to him as my gastroenterologist. However, my request was denied after Dr. H's input citing that patients can't switch doctors within the practice. Their secretary staff are at least quick to comply with sending over medical records to my new gastroenterologist or other doctor's that may need my medical summary history performed by Dr. H. If you have the option, I highly recommend seeing Dr. Trivedi. My mother sees him, and two other doctors I know absolutely adore him as well. It's just unfortunate that I'm not allowed to be one of his patients!

When I called with an insurance question she didn't have the answer to, Emma was forthcoming and apologetic. Her voice imparted kindness and care which mattered much more than the information I had called about as a new patient. The day of my appointment I had difficulty finding the location and Emma patiently and kindly helped me first with my anxiety over being late and later with figuring out how I could still see the Dr. when I ended up finally locating the facility and being extremely late. The Dr. was also lovely and friendly and very kind to me about being so late. He spent as much time with me as I needed to understand my condition even though he had every right to have not seen me that day at all (since I was so late). I was impressed with my entire experience knowing that Dr. Navabi carefully selected a technician like Emma to represent his practice in a caring way. :) In a world that can feel more and more disconnected, emotionally intelligent young women such as Emma are more valuable than ever. Well done Dr. Navabi, knowing how important your representatives are. Well done Emma! Who you are in our world is valuable and urgently needed! :) And also the Dr. seemed lovely and he made me feel seen and heard. :) Much appreciated. Thank you so much! :)

I also had problems with his office staff not following through, etc., on things prior to this.

On a follow up visit one of the staff members was more accommodating and another one was talking to me about seeking another expert opinion outside of Dr. Chen since his diagnosis didn't make much sense. There are multiple things I was not fond of when it came to his practice and overall a bad experience for my first time seeing a specialist in his field. 1) even with insurance his prices aren't cheap and for the quality of service you receive it's not worth your money 2) he prescribed me a medicine that caused me to have horrific side effects and after telling him that sent me to the ER midnight for ten hours he didn't have any comment to make. I emphasized the bill was over $350+ with good insurance. . 3) during my 2nd appointment the research I looked up seemed to have matched his "knowledge" and he didn't have any answer what so ever on what could be causing my abdominal pain (bingo: it was the medication) He insisted I stay on it for another month when I said there was no reason to since my initial concern was already solved? The medication doesn't target abdominal pain so why would he want me to do that after repeated mentions of side effects? Regardless I entertained it for five days and felt awful, I couldn't function at all and immediately stopped using it. I've been better since. . How does that work? On top of that he walked out mid-sentence when I was bringing up how I waited over an hour to be seen when I was on time for my appointment and he had no answer or advice to give while just saying "I'll book you for a month out for now with a revisit" What?? I've cancelled my appointment and kept all the receipts because the business seems like he just wants more $$$ than anything. This is my honest review and experience with him and I won't be removing it unless he offers me a full refund of both appointments. He's very lucky I'm not asking for the ER fees which is seriously ridiculously high. Awful. .

They no longer have a Patient Portal (supposedly working on it for months now) and it's very hard to reach anyone in their office. Mostly you get directed to voice mail.

It's been well over two weeks and when I called (after multiple attempts) I was advised the doctor had reviewed the results a week and a half after the procedure but never bothered to let me know. He saw the results two weeks ago and no word. I have been seeing Dr. Chen for several years but I am becoming extremely discouraged with his practice.

She quickly put me at rest with her compassionate and positive bedside manner. After her very thorough examination, she scheduled multiple tests. These tests identified serious but treatable GI issues, a hormonal imbalance, and a large ulcer that I was completely unaware of. Within a short time after starting treatment I was a newer better version of myself.
