She is such a caring and very experienced doctor. So easy to talk to and she makes you feel like you're special.

I've been going to Dr. Hierro for over a decade. She's wonderful! If fact, I travel from Washington state because she's that good!

Dr. Hierro is a wonderful doctor and has performed all my colonoscopies. She has my complete trust, and is an empathetic and kind person.

I was a first timer patient of Dr. Farid's and had a wonderful experience with her and her staff. I…read morewas referred to her from another doctor for an evaluation and treatment which I always try lead with referrals when it comes to anything medical. I tend to get bad anxiety with doctors offices and Dr. Farid had an excellent bedside manner (I've unfortunately experienced doctors in the past who do not). She was exceptionally kind, answered many of my questions before I even had the chance to ask them, and took her time to respond to each of my questions. She was steady, confident, and kind which I truly value in a medical practitioner. Her team all echoed the same values as well. I would highly recommend!

HORRIBLE. Over the…read morelast 6 months, I've been rescheduled 3 times with different doctors for an upper endoscopy; I was just called today because the most recent doctor I was scheduled to handle my procedure, which is supposed to take place NEXT WEEK, doesn't actually do the procedure (whaaaat??!). UCLA Gastroenterology, please get your act together. How did you guys book me with a doctor who doesn't do this procedure, and you just caught it after I booked the appointment almost 2 months ago? I just wasted 6 months going back and forth with UCLA. The next available appointment isn't for about 3 months for now. Word of advice to you if you're reading this: call UCLA to make sure they actually set you up with a doctor who is authorized to handle your procedure. Look elsewhere if you want to get care from a team that has their operations set up effectively. This feels like a terrible April Fool's joke.

I have been a patient of Dr. Martyak's for over ten years. As a doctor myself, I have no problem…read morebeing judgy or picky or critical of other doctors. Dr. Martyak is what I wish all of us in the profession could be-very current on knowledge, thoughtful, empathetic, and deeply caring. Dr. Martyak treats me for GI complications caused by other medications that I have to take despite their horrible side effects. She thinks outside the box and goes the extra mile to make sure I'm okay. I go years without needing her aside from the recommended GI maintenance, and then there are times during which I desperately need her help. She and her amazing front office are there every time. Dr. Martyak recognizes that this stuff is hard for most of us to talk about, including me. You can say anything and she will receive it with concern and a deep understanding of how important personal dignity is. I love that she keeps both short term comfort and symptom management as well as long term plans front and center. I cannot recommend her highly enough. My husband is also a patient of hers and would agree wholeheartedly. I take tremendous comfort in knowing that she is ready and willing to take on my rather complex GI issues with a true understanding of how hard this stuff can be on your quality of life. There are not enough stars to rate her as I'd truly like to. She's a godsend and I feel so much better both physically and emotionally in her care.

I tried to have Dr. Martyak help me with the same chronic issue for YEARS. Never did because she…read morewouldn't physically examine me (eg look at the issue) - only talk to me or have PA do a Zoom. Went to a new doctor. Diagnosed in 5 minutes. Over the counter solved the problem immediately. Another example of lack of care or attention.

I really hate to leave this review because Dr Dixit is very kind…read more However, I can't give him 5 stars for his medical ability. If you need a colonoscopy or an endoscopy and that's it, then I highly recommend Dr Dixit. If, however, you are having mystery symptoms and need help diagnosing them, I would not recommend him. He is not a very skilled diagnostician in the GI field and regularly wrote me off when I tried to broach concerns with him. He left me in limbo about Barret's Esophagus for a year (when another GI was able to clearly tell me I did not have it.) Despite being hospitalized 5 days in a row, his office refused to squeeze me in and wouldnt see me for a month. If the doctor is truly that busy, then that's fine, but I just cant see a doctor that refuses to see established patients who are having emergency level symptoms. When his office refused to see me, I sent him images, which he said he couldn't read and suggested I wait until my liver starts to fail before I remove my gallbladder. Needless to say, I found another doctor who was able to see me quickly and help. Take the feedback for what is is - if you just need a basic colonoscopy, then I highly recommend him. If you need a doctor who will help you resolve/solve/diagnose issues, I'd search elsewhere.

Getting to that age when u need a colonoscopy is not fun. I hand picked Dr.Dixit by some of his…read morereviews. I had a great feeling and I was 100% right. When a doctor enters the room and starts asking about you , where u are from and about your family instead of just looking at paperwork and getting right to business you know you are on the right path. Dr.Dixit is very personable and clearly knows what he's doing. Even on the day of the colonoscopy he was in the procedure room talking about puppies and making me feel at ease. You can't find doctors this cool nowadays. Would be nice to have Dr.Dixit as my GP. Trust me, you can't go wrong here for a colonoscopy with Dr. Dixit. As far as the office goes. Everyone there seemed quite nice. Very quick and quiet with Covid-19.
