I can honestly say this was the first time I used a doctor that I found on Yelp. I hit the jackpot! Dr. Nattiv was as wonderful as everyone said. He was patient with my son, and you could see that he truly cares about his patients. So grateful that my son is under his care. I am updating this post a month later. I am telling you that Dr. Nattiv is a GEM. You will not find a more caring doctor or nicer staff. read more

Dr. Nattiv came highly recommended by our pediatrician. We came to him for a second opinion, but wish we had come to him first. We didn't realize he did telemedicine which meant we didn't have to drive for over an hour with a child who gets carsick easily. His warm demeanor put us at ease right away. We explained our child's situation and he listened patiently, we NEVER felt rushed. He then explained what was happening based on bloodwork, ultrasound and Tiny health stool test. He cited recent studies, gave us a clear diagnosis and explained it to us in an easy to understand manner that made us feel relieved. He gave us an RX for medication which our old gastro did not. We asked questions and he was just very generous with his time. You can tell he is passionate about his work and his bedside manner and knowledge is unparalleled. He followed up with with an email with the journal articles he cited. We felt so much better after our appointment and glad we found such a incredible doctor. read more

Dr Nattiv is very patient and very knowledgeable. He took is time and answers all questions with patience! I highly recommend him he is amazing read more

I took my infant son to see Dr. Nattiv after he had been struggling with gas and general GI discomfort for months. I explained our history and Dr. Nattiv was very patient, caring, and thorough. He asked questions and clarified his understanding. At no point during our visit did I feel rushed or unheard, which I feel is very rare these days in doctor's offices! I would absolutely recommend his care to any other moms or parents. read more

Hands down one of the best doctor I must say. It was our first visit (recommended by another one of the best Dr Emily Bruckner) and felt like we've been visiting him since long time. So very down to earth, so much of patience, no rush (he gave almost 30 minutes to us) a good listener and explains what's going on with the kiddo in detail with proper instructions on what to do and what not to (with a proper hand out). Also the staffs are so good there. When I first called them earliest appointment was after couple of weeks. But since my kid was vomiting everyday (even after his ER visit) we requested an early appointment and without any chaos the manager called us back to prepone our appointment. She gave the dates of just 2 days after. read more

There is a reason why Dr. Nattiv has such good reviews. Even before our first appt, I had questions around insurance and Dr. Nattiv himself (yes that's right not his staff) took the time to call me to discuss it and reassured me on how everything would work. Doctors have very busy schedules and the fact that he himself called set the stage that my daughter would be in good hands. In our first appt, we shared our daughter's history on poor eating habits, stomach pain, vomiting, low weight gain etc. Dr. Nattiv recommended that we take blood tests. He didn't suggest just normal blood tests but the ones that really would give answers to the problems our daughter was facing. He also asked us to do a very specific stool test to hopefully get us some answers. He also recommended a specific formula that would help in not getting as full but getting the same calorie content as well as which would digest more easily. Our little one has been complaining every day since a year about stomach pain and with this new formula recommendation, we haven't heard her complain since the past 3 weeks (fingers crossed it stays that way). The blood tests and stool sample gave indication on what may be happening with our daughter. Had the right tests not been ordered we wouldn't have answers. To be very frank, we have been dealing with many doctors and no one has really been able to pinpoint our daughter's problem. While it's too early to say if everything is going to be fine with our daughter, having been 2 months under Dr. Nattiv's care makes us feel more comfortable and at ease that we are hopefully on the right track. Dr. Nattiv also shared future courses of action if the current course didn't work out. He is extremely articulate and explained everything to us in lay man terms. He could presume what questions we could potentially ask and answered them before we asked them. He also took the time to write up a letter to insurance to cover the formula. He also gave us his email if we have any questions and yes he did reply to all of our queries when we reached out on email. To say Dr. Nattiv is good is an understatement, he is simply excellent. Fingers crossed, our little one has limited stomach issues down the road and grows to be a healthy child. Thanks Dr. Nattiv for everything you have done for us, we can't thank you enough. read more

Dr. Nattiv took all the time we needed to thoroughly address all of our issues. We left confident that our little one would feel better soon and he did! read more

Dr. Nattiv is a wonderful doctor. He has a great expertise in his area and always listen to the parent's concerns and worries. He is always available to discuss any issue and makes himself available. He is truly concerns about children's well being and is willing to go out of his way to help his little patients. I would recommend him to anyone without any hesitation. read more

We are so fortunate to have Dr Nattiv as our daughter's doctor. As a doctor, in terms of knowledge and being on the cutting edge, he is absolutely top notch. He is an exceptional doctor. But there's more. Dr Nattiv approaches every visit with patience and time. We have never felt rushed. He makes us feel like we're his only appointment for the day. He will not end the appointment until he is satisfied that we're satisfied. One of his super powers is his way of connecting with my teenager. The way he listens and hears her, and addresses her concerns is unmatched. We are so grateful. We know we are getting the best medical care possible from Dr Nattiv. read more

Gave quick appointment . Listened patiently to all concerns. Ordered elaborate testing. Was easily reachable even after appointment.

Dr Nattiv, You are awesome. Thank you for all the information, help and advice you gave for my two month old. You resolved the issue that not even my pediatrician could and for that I am very grateful. Highly highly recommend!! read more

Dr Nattiv is the best GI pediatric doctor you can find. He was extremely attentive to me and my family and answered all of our questions. We could not figure out what was bothering our 3 week old and Dr Nattiv took the time to speak to us and find out the issue. He made multiple recommendations and worked with us until we figured out the issue. We owe him a lot for all that he has done for us and our family. I highly recommend him read more

Our son was diagnosed with IBD at almost 16 years old. Dr. Nattiv immediately made himself available to us as a whole family. He took all the time necessary to explain answers to all of our questions sometimes spending an hour with us when necessary even though his schedule was busy. He visited us during one of our son's first infusion session despite having rounds that day. He never made us wait to hear test results and always explained the results in a way we could understand. Dr. Nattiv has made a scary life-long diagnosis, something we could manage every day. I highly recommend him. read more

Excellent!!!!!! Very professional !!! Take time to asked to the patients about the conditions he is kind of the doctor we need it !!!! He has a good stuff very nice and patience Perfect !!!! Treat , customer service, profesional read more

Let me start by thanking Dr. Nattiv! There is nothing I can do or say which can demonstrate my appreciation for him. My son was diagnosed with C Diff and along with it, came things that we were just not aware of. My wife and I were scared beyond imagination and started looking for a Pediatric GI Doctor. After speaking with multiple doctors, Dr. Nattiv's name kept coming up. After speaking to him, he scheduled us in IMMEDIATELY. We went in and he took an hour just answering all of our questions. He then ran additional tests (beyond what our Pediatrician did, and our Pediatrician is AMAZING as well). Immediately after meeting with us, he contacted our pediatrician and discussed everything with him. He didn't just go with his course of treatment without consulting with our son's Doctor, he wanted to make sure everything was done correctly based on my son's history. He then searched for a pharmacy that did compounding near our house. Called in the medication and you would think well, he's done everything he needs, right, wrong!!!! He followed up with us EVERY DAY until he was sure my son was doing well. He actually still follows up. There is nothing worse than your child being sick, but having a Doctor like Dr. Nattiv is truly a blessing. Dr. Nattiv is incredibly knowledgeable, thorough, friendly, and simply one of the best doctor's I have ever met. read more

There aren't enough good things I can say about Dr. Nattiv. We've seen a few GIs for my son's issues and none of them showed half the amount of compassion or care as doctor Nattiv did. He spent a lot of time with us in his office and even outside the office with emailing and guiding us with our research. He has put my son on the correct path and has calmed our nerves by giving us a plan and really believing in it. Thank you so much Dr. Nattiv for caring about my son and treating him like you would one of your own. We are grateful to have found you and my son is blessed to have you on his team. Thank you!!! read more

Dr. Nattiv is amazing. He is very thorough, he takes the time to listen to your concerns and is genuinely invested in your child. You never feel rushed l, he takes the time to ask and answer every questions you have. He's very down to earth and approachable. He followed up himself to see how my son was doing, which is hard to find in a doctor. His front office staff was also very nice! Highly recommend him! read more

Dr Nattiv is the best doctor I have ever seen. My newborn baby was having extremely challenging GI issues that other doctors were not able to identify the cause of the problem. Dr Nattiv spent a significant amount of time with us to listen and watch what was going on, he explained everything to us and was able to diagnose the issue immediately. He is extremely well researched and shares his knowledge which I found incredibly helpful. I couldn't recommend him more. read more

I strongly recommended dr. Nattive for all the parents who look for a excellent doctor. I believe that Dr. Roy Nattiv is the best pediatric Gastroenterologist in California. He is extremely knowledgeable and specially very nice to the kids . He spend so much time explain everything that I need to know about my baby test and he was so patient about all my questions. Thanks god that I find Dr. Nattiv read more

I wish I could give Dr. Nattiv 10 stars as he is absolutely the best! From the moment I called him with an urgent matter regarding my son, he went out of his way to listen to my concerns and provide solutions immediately even though it was not during clinic hours. His dedication and caring demeanor are what sets Dr. Nattiv apart from the others. Not only does he have an incredible rapport with his patients, he is an adept skilled diagnostician who hones in on the problem immediately. He is also not one to order unnecessary tests or procedures which I appreciate. He has a methodical approach which works! If you are looking for someone you can trust with your child's well being, look no further. read more

Dr Roy Nattiv is one of the very few doctors in LA (USA?) that actually seem to care for his patients. He is attentive, responsive, open and respectful towards your preferences and very knowledgeable. He has gone above and beyond to help my son and I am forever grateful. I feel safe and cared for in his practice. Can't recommend enough read more

I can't say enough about Dr. Nattiv. We went through a very traumatic experience with our daughter, his expertise, compassion and professionalism rose above many of the Doctor's we've dealt with. Dr. Nattiv takes the time to listen and is extremely attentive following up with any questions. The mutual connection was immediate and comforting and felt our daughter is in the right hands. So in these short words......I highly recommend Dr. Nattiv to all parent's looking for a pediatric Gastroenterologist. read more

Dr. Nattiv gave me a call personally to help with scheduling my daughter in. It was a great gesture! Thank you.

We love Dr. Nattiv! My teenage daughter has been seeing him for almost 2 years now. He's very caring, attentive, and most importantly listens to how the parent feels. Luckily my daughter will be able to continue to see him until she is 21. He is also very knowledgeable. I have also referred other patients to him and they have also liked him. Thank you Dr. Nattiv!! :) read more

I brought my son in to see Dr. Nattiv after reading the positive reviews here. Dr. Nattiv was very friendly and super thorough. He spent close to an hour with us hearing my concerns, reviewing lab work, and taking notes. He gave us his full attention and asked a lot of questions. What I liked most was, at the end of the visit, not only did he have clear recommendations, but he gave me a printout which outlined all of them. When you are with a fussy baby that you are trying to keep calm during a doctor's visit it can be easy to lose focus and not retain everything the doctor says. And so many times I leave a doctor not really even knowing what the next steps are. I felt really reassured having seen Dr. Nattiv and felt like there was a well thought out plan going forward. He even followed up with me by email after our visit. I don't think any doctor has ever done that with me before. read more

Pretty passionate and well rounded doctor. He got us in within a 24HR emergency visit. We appreciate the thorough visit and helpful suggestions. Our LO is doing much better after we visited Dr. Nattiv. read more

Our son's pediatrician recommended Dr. Nattiv to us because our son was having problems having bowel movements. Dr. Nattiv did some X-rays on his tummy and found that there was some intestinal blockage. He outsourced some additional testing to Quest Labs, who, after receiving three days of stool samples from our son, returned the results to Dr. Nattiv to be analyzed. During this process, Dr. Nattiv was constantly reaching out to us, asking how our son was feeling, making sure there were no signs of anything damaging. He called and texted regularly and more importantly, was available to us seemingly 24 hours a day to answer any questions we had through texting. Even more important was that we never had to wait a long time for a response. Once he received all the results, he called with the results and had them visible through an online portal I could access. I couldn't have been happier with his care and professionalism. If more pediatricians were this attentive, doctor's visits would be a lot less stressful. I highly recommend him! read more

We were referred to Dr. Nattiv because our infant son was excessively colicky. Dr. Nattiv was very methodical and knowledgeable. He determined that our son had some reflux and food allergies. We started the elimination diet and it helped. Overall, we are so thankful to have met Dr. Nattiv. In addition to being an excellent doctor, he is also patient and very responsive. He always responded to our emails and calls in a timely manner. He was great at following up. And he is very kind. We really trust his expertise and are forever grateful for his help! I recommend him to anyone looking for a solid doctor for their little one. read more

Dr. Nattiv was really great with our son. My son had stomach issues which resulted in very little weight gain and growth. We were questioning if he had chrohn's or celiac. We ended up getting him a colonoscopy and endoscopy. The procedure was quick and with the exception of a sore throat my son was playing outside by the afternoon. What I like about Dr. Nattiv is that he really showed a concern for our son and he spoke to him at his level. My son can be quite a challenge and Dr. Nattiv's approach was refreshing. The good news is that my son does not have chron's or celiac and with the help of Dr. Nattiv he has gained weight and had a little growth spurt. read more

Amazing doctor. My 2nd and 3rd child had GI issues so I used pediatric GI's for both of them. I didn't know about Dr. Nattiv until I had my 3rd and I wish I knew about him before. He's so thorough and caring. He spent so much time w my daughter, watching me feed her and coming up w a detailed plan of action (w a which he printed and gave me to take him. I don't think any doctor has spent this much time w any of my kids at any doctors visit. He also was so generous to talk to me on the phone between visits. Anyone who has a baby w GI issues knows the anxiety moms can have when your baby is spitting up, not drinking milk, and not gaining weight. And to have to wait weeks to see the doctor again can seem like a lifetime. Dr Nattiv helped me tremendously between visits. He was beyond great, I would highly recommend him. read more

Dr. Nattiv is a great doctor! Not only is he clearly very smart, his bedside manner is incredible. He takes the time to thoroughly answer your questions and puts together a plan for you to follow, and he is responsive over email. To have a doctor that's completely engaged and doesn't seem rushed is a rare thing these days. He is also so sweet with kids and is super nice! As a parent, I could not ask for anything more. We are so thankful we found Dr. Nattiv! read more

Dr. Nattiv is patient, compassionate, and incredibly knowledgeable. A friend of mine referred me to Dr. Nattiv because my 6 week old baby was having what seemed like an abnormal amount of digestive issues. He is my first baby; I have no idea what is considered "normal", and I would feel so helpless when he would seemingly writhe in pain from what looked like gas pains. The office itself was clean and the staff was very nice. Starting from my very first phone call, the they were very informative and accommodating. Even better, they accepted my PPO insurance plan and billing was very simple. Dr. Nattiv was so friendly and so patient with us. He was very thorough in taking our little boy's medical history and doing the exam. Luckily, we brought a baby journal with us which we use to track our baby's feedings and dirty diapers (pee vs. poop). He was very very informative about what was going on with our baby and explained everything in simple terms we could understand. After explaining everything, he came up with a game plan for us to help alleviate our son's pain. Fast forward a couple weeks later, my son's digestion has improved dramatically. We've also been in touch with Dr. Nattiv to update him about our son's weight gain. I think that's to make sure there are no bigger digestive issues which I really appreciate. NOTE: There is parking in the building but they don't validate. The staff was gracious enough to mention that to me during my initial phone call. Overall, I highly recommend Dr. Nattiv for any parent who has a child with digestive issues. read more

Let me start off by saying that I drive 2 1/2 hours including the horrible traffic on the 405S just to get care for Dr.Nativ. I've been struggling for the last 4 years to find my daughter the proper care she deserves. When I came in to this office they are very kind and attentive. I did not feel rushes or left with any concerns. My daughter is scheduled for a follow up next week and I have no doubt I'LL be WELL TAKING CARE OF!!!!!!!!! read more

I am so glad to have found Dr. Nattiv. He was amazing with my 2 year old and made my son feel very comfortable. He was the first doctor my son hasn't screamed at. I was like Amen this doctor must be good! Dr Nattiv was very informative and was the first doctor that gave me hope that we can resolve my sons tummy problems. I have confidence in him. The nurses at his office were so kind and friendly. We are looking forward to our next visit. read more

We are very happy with Dr. Nattiv.. He is extremely patient and kind and he will spend as much time as you need to answer any questions or to inform you about what might be going on with your child. Our 3 year old has been struggling with constipation issues but since following the doctors instructions our son is getting better fast.. we really appreciate the time he spends with us in our appointments.. we don't feel rushed and he seems to truly care for the well being of our son. Thank you Dr. Nattiv. Sandra read more

Dr. Nattiv is amazing! We first met him while my daughter was in the hospital. He took the time to review her history and very thoroughly explained to us what was happening and what steps can be taken moving forward. I was in desperate need of answers for my daughter's chronic stomach pain that was getting in the way of her daily activities. For an active teen, this was debilitating. He checked in on us first thing every morning during the hospital stay with calls in between. Since then, he has diagnosed and treated my daughter's symptoms and her pain is minimal. He is really thorough in active and proactive measures in making sure he is doing everything he can, and really knows how to communicate with the parents and TEENS! As a parent I really appreciate Dr. Nattiv who can speak to a teen and to parents on levels we both can understand! LOL Because my daughter is a TYPE A honor student who basically lives on campus due to many extracurricular activities, he also made sure the school understood the accommodations his patient will need during school hours due to her symptoms. Dr. Nattiv is absolutely amazing and I am so grateful for his care!!!! read more

I cannot say how thankful I am for Dr. Nattiv. My 13-year-old daughter was having stomach pains for weeks. I called a few pediatric gastroenterologists only to be told they could see her in a month. Not an option to wait. She was in pain every day. Dr. Nattiv made the time to squeeze her in and spent over an hour with us. He had the foresight to order an extensive stool test, which showed she had contracted a very rare bacteria. My own GP, a naturopath, and her pediatrician all agree that many gastroenterologists may not have even tested for this bacteria because of its rarity. He has since made himself available to speak to us on weekends and evenings to follow her progress. What a gem he is! read more

Dr. Nattiv is a fantastic doctor and a wonderful, caring person! Our son's pediatrician recommended Dr. Nattiv to help our infant son with tummy issues after a scary visit to the ER department when he was 3mos old. My son was crying when we walked into Dr. Nattiv's office and the first thing he did was lower the lights to help calm him down - that alone told me he wasn't just an ordinary doctor. What makes Dr. Nattiv so terrific is that he weaves his experience as a father and his amiable personality with his medical expertise to collaborate with his patients' parents. He's an excellent listener, very thorough, always responsive and goes the extra mile to help his patients. Both my husband and I highly recommend him! read more

Dr Nattiv is amazing! My 4 week old son was very sick with acid reflux and food allergies and Dr Nattiv called personally to talk with me about the issues and squeezed me into his schedule for an office visit the next day. He was so thorough and the care he showed my son was wonderful. We are beyond thankful and lucky to have found Dr Nattiv! read more
