Dr. Marcus saved my life. I had a perforated appendix & sepsis had set in. He performed emergency endoscopic surgery @ was able to get rid of the infection. It was very scary. I was in the hospital over a week. I am now - a couple of months later- back to normal with minimal scarring. I am grateful to Dr. Marcus & his team. G. read more

Dr. Marcus is an incredibly caring and professional surgeon. He performed my surgery and checked up on me regularly. I highly recommend him . read more

I was admitted to Cedars marina del Rey, and needed emergency surgery. I was extremely fortunate due to the severity of my condition that DR. Marcus was available for me within hours. His presence immediately put me at ease, and I feel he literally saved my life. His office is right across the street from the hospital, he and his wonderful staff have been there 100 percent for the after care. I highly recommend Dr. Marcus, he's not only an impeccable surgeon, he genuinely cares about his patients and I felt very safe under his care. read more

Forever traumatized. He discontinued my care after filing a grievance. Fractured my relationship with any medical provider. I wouldn't recommend. Please ask your pcp for an alternative option. Dr Marcus is only interested in billing your insurance. He botched my all my surgeries. I'm so heartbroken that he would do this. read more

I had a friend see this physician as someone who works in healthcare, to leave someone with what they did not want on there body and try to gaslight them because they are a female that the monstrosity that was left on them is just normal is infuriating. If I could give this doctor zero stars I would. Shame on this doctor, to then decline continuation of care for speaking up is the reason why patient don't feel safe seeking help to begin with. read more

Entirely traumatic experience. Failed / botched procedure. Zero interest in remediation, rude, argumentative and defensive. Flippant and dismissive, nonchalant level of care at best. Poor communicator. An unfortunate and debilitating choice. Keep shopping and ensure you see a specialist for your situation. read more

I saw Dr. Marcus September 27, 2023. I had been referred to him by my primary for rectus abdominis diastasis associated with a debilitating injury I had to my abdomen during massage therapy. The reason I sought a surgeon out in the first place, was not because of the rectus diastasis that tore my linea alba and rectus sheathes off my rib cage. It also damaged my external, internal obliques and / or transversus muscle and the corresponding layer of aponeurosis. During the appointment, Dr. Marcus had me do sit ups and evaluated how my rectus abdominis muscles functioned...a muscle group that did not concern me and did not come to him for evaluation of. He did not evaluate the obliques and transversus that I had told him were defective. During that sit up evaluation, which I could barely do correctly, I started to spasm from associated nerve problems. He said to me that he didn't want me to shake like that, and to only do the sit up he requested. I told him I wasn't even doing that on purpose, like I couldn't believe he thought I would intentionally shake like that during an otherwise routine movement pattern. He also told me that the defect (muscle tear) was completely fine because the other muscle groups around it would take over and compensate, which made me think he was talking about the rectus abdominis injury from a ventral herniation. After reviewing the report It's clear that the reason I was actually there wasn't addressed at all. The obliques and transversus muscles are important muscle groups for stability and connection of the ribcage and abdomen that are layered on top of each other to the right and left bilaterally of the rectus abdominis muscles. Those have layers of aponeurosis connected between them and to the ribcage across the abdomen and form the linea alba, semilunaris, tendinous intersections, rectus sheathes and do other minor almost inconsequential things like holding all the abdominal viscera in place. I have no idea why my primary keeps referring me for rectus diastasis when I tell him the specific areas I have unanswered questions and needed evaluation for. The medical coding system is screwing patients out of proper evaluation because some injuries do not fall within that system of codes for referral. I came in for obliques and transversus shutting down or tearing off my ribcage that I HAVE reports corroborating, I got evaluated for rectus diastasis and damage to my rectus abdominis muscles I didn't need. Great. read more

I am 81 years old, so of course I have lots of experience with doctors. Dr. Marcus is a general surgeon who specializes in minimally invasive procedures and surgical repair of hernias. He is one of the top three of my doctors for whom I hold the greatest esteem and respect. He and Mr. da Vinci, his robotic associate, did three hernia procedures in one surgical session on me recently. One of these hernias was quite large and had been diagnosed as a lipoma by other doctors. While in there he also checked in on an inguinal mesh hernia surgery that he performed for me about six years ago. Result: happily, it is still very solid. I had some anxiety and concern about having to deal with four separate hernias, but he dispelled that concern, saying "Some people have freckles - you get hernias". I was pleasantly surprised about how short the recovery period was, and how quickly I could get back to working my core in the gym ! He's just a really nice guy, and has that kind of personality that puts you at ease and makes you feel like you have been friends for a long time. An understatement: his background is impressive, especially considering his pioneering work in robotic surgery. Without hesitation, I would refer anyone with hernia problems to Dr. Marcus. Gerald F. Johnson. 6/23/24 Manhattan Beach, CA read more

He's an amazing doctor and robotics expert. Hernia surgery virtually painless and recovery very short. Highly recommend. Do your research. read more

My own review in the beginning was delayed so now I speak. Actually the service provided to me was of the highest quality under any circumstances, he and his staff were caring kind and professional in every aspect of dealing with My condition, the explanation of events were explained and followed up to resolution. I know this if I need the services of their office I am confident in what they do and would recommend Dr. Marcus to anyone as he is straight forward in his assessment and treatments thru following up with you until you Happy with the results. read more

Dr.DanielMarcus is an incredible surgeon. Him and his staff are amazing and made me feel super comfortable before and after my surgery. He's one of the top general surgeons in Los Angeles and I'm forever grateful to him for helping to save my life. read more

"someone saved my life tonight" Elton John I was admitted to Cedars Sinai ER with a significant lower GI infection. I was in a very bad way!!! Despite the late hour, DR Marcus assembled his team and treated my issue!! I am grateful John Skidmore read more

There are not enough superlatives to describe Dr. Marcus! I recently had an emergency appendectomy and I was home 24 hours later with minimal pain and able to function on my own. And I'm almost 70 years old...although I hate to admit it. : ) His expertise and skills are remarkable. I hope I never need surgery again, but if I did, he is the only doctor I would consider. I feel so blessed that my primary doctor chose Dr. Marcus for me and that he was available. Thank you Dr. Marcus! read more

Dr Marcus performed robotic surgery on my wife. We were truly grateful having him and his professionalism at our side. He performed colon resection and her recovery time was 2 days 21 hours, that's when she was released. Totally unbelievable! We always recommend him whenever we can. Thank you. read more

I recently had Robotic / Laproscopic hernia surgery performed by Daniel Marcus. Dr Marcus is foremost in this field having performed over 800 of these surgeries. He is thoroughly knowledgable and lets you know exactly how the procedure is done and then does exactly that. I was in and out of the hospital in 4 hrs with the surgery taking about an hr and a half. Down time was minimal because of the nature of robotic surgery. I was walking outside in three days Six days later I am up and around with all hernia problems and pain behind me. If you have a problem with a hernia and are undecided about a surgeon Dr Marcus should be your choice . I strongly recommend him. read more

I was referred to Dr. Marcus by my primary doctor Dr. Gilmore . I had been battling hemorrhoid for about 3 years and had seen other doctors that did not make me Feel comfortable about having surgery. The first time I came to see Dr. Marcus he explained that the surgery was so simple it was going to be an outpatient surgery, very simple...he also said that if I'd like I could speak to anyone of his patients that had this surgery.. to which I decided not to because we are all different and react to things differently. I decided to go ahead and book my surgery and hope for the best. 3 days before my surgery I started taking milk of magnesia .. the day of the surgery I had zero water and zero food. My surgery time was 1:00 pm I arrived to Marina Del Rey hospital at 11:00 checked in and was with IV in my arm by 11:30.. Dr. marcus Gad a complicated surgery in the morning and was running behind 2:00 hours to which I thought was going to make me nervous but the nurses made me feel so comfortable I was calm, cool and collected. At 4:00 pm I went in ... my surgery turned out to be a little longer than he expected because he did have to complete cut the hemorrhoids off. I went home a little after waking up. Slept until the next morning. The following morning when I woke up I was expecting lots of pain he prescribed me NORCO.. but also said if you can handle the pain and just take TYLENOL please do that. To my surprise there was ZERO PAIN.. nothing and it continues like this for the next three Days . No pain just felt a little discomfort. I must say I stayed laying down for two days.. had milk of magnesia 15 ml at night, 3 spoonfuls of mineral oil though the day, and took my anti-inflammation pills one in the morning one at night.. and followed all instructions. I am at day 5 and feeling much much better !!!! If you have this issue I would suggest going with this Doctor! He's a rock star! read more

OUTSTANDING! It is a rare occasion to find a surgeon who is NOT arrogant or self-centered, takes time to talk to you, not at you and shows a true compassion for your situation and needs. One such surgeon is Daniel Marcus. Having the need to repair an incisional hernia from a previous surgery, I was referred to Dr. Marcus for a consult and examination and after waiting a full year to perform the procedure, I returned in the middle of the Covid pandemic. A remote video 'examination' ensued and we set a date. I was concerned about post-surgical pan and recovery time. I needn't have worried. The outpatient robotic procedure went off without a hitch and after a 3-1/2 hr operation and an hour in recovery, home I went. NO PAIN, NO DISCOMFORT nothing. Just a few little holes in my abdomen. It has been 4 weeks now and I am more than totally satisfied with the outcome. I would recommend Dr. Marcus in a heartbeat. read more

My wife Ana was referred to Dr. Marcus by Dr. Firoz Sheikh, our internist, after suffering a biliary colic attack. At that time we had just moved to the US (we are both Spanish) so we were not too sure how the health system worked here, and what to do if surgery was required. Dr. Marcus quickly diagnose my wife with gallstones and suggested surgery as soon as possible, to avoid any possible future complication. He explained very well to us the whole process and we automatically felt we were in good hands. Just a few days later, Ana had gallbladder surgery by Dr. Marcus, using minimally invasive state-of-the-art robotic technology that required just one incision in the belly button. Ana could leave the hospital just a few hours after the surgery, and within a few weeks she was fully recovered. She is now eating perfectly and having a normal life. Dr. Marcus is an outstanding surgeon who really cares about his patients. On one occasion, Ana required a post-surgery medication while we were out of town on a Friday night and Dr. Marcus kindly personally rang a Pharmacy near where we were staying and we quickly got the drug. We can only recommend him for any general surgeon inquiry you may have. read more

If I could give zero stars I would. First they don't take health insurance. Secondly my appointment was for 9:30am, I arrived ten minutes early to fill out paper work. At 10am I asked when I was going to see the dr and they told me he was with another patient right now. Probably the patient that came in after me that also had an appointment at 9:30. I told them I had to leave I had to go to work and they said he'd be a few more minutes if I could wait. Well I can't, I have to go to work just like you have to be at work right now lady. Then they called as I was leaving seeing if I could come back in. Then offered me an appointment later today and appointment for tomorrow. If appointments are so open why on June 2,2017 did you tell me the first appointment available is june 27,2017? I waited a whole month to not even see the Dr. and then paid to park. I came her because I had surgery on a hernia in feb that didn't take. I was coming for a second opinion and hopefully some good news since my first surgery didn't work. Guess Ill have to keep looking for a surgeon. I wouldn't waste your time here unless you're retired and have nothing else to do with your day. Also, cant say whether or not the Dr. was great, I'm sure he is, but I never got to see him. read more

ZERO should be an option here. I don't know how this guy can run a business. I called after being referred by my GP to make an appt. No answer, left a message, no return call. Went online as the message said that was an option, went smooth and I thought okay this seemed to work. NOPE! Called them twice that day to see if the appt was actually scheduled. No answer, no return calls. Today was my appt and I called twice this morning to make sure it was okay, no answer, no return calls. So, I went in for my appt I booked online per their own message center and they said they were sorry but he was in surgery all day. Then they said they could get me another appt so I said hmm okay well let me give you my insurance card. THEY DON'T TAKE INSURANCE! This should be big bold letters on the front page of their website. She went on about matching whatever insurance rates I had and perhaps they might be able to do that... MIGHT? I mean HELLO I have GOLD PPO and pay through the nose for insurance for this very reason. I needed to see a specialist. Guess that staff specializes in the run around... seriously. Dr Marcus might be the best doc/guy in the world. The staff and experience I just had is clear his business will fall to customer service issues. What a joke! To really make the day I went out to my car and low and behold it took them 16min to figure out all of this BS. So I got to pay to park due to 15min free had elapsed. My advise - DON'T WASTE YOUR TIME. read more

Outstanding surgeon. I ended up in the Marina Del Rey hospital ER a few weeks ago and it was Dr. Marcus who identified a diseased gallbladder. Were it not for his intelligent diagnosis and swift move into surgery, I would have suffered quite a bit given the state it was in. Highly, highly recommended. read more

Dr. Marcus spent five extra hours on my surgery to make sure everything went the way it was supposed to. it was supposed to just be a simple hernia repair, but there were numerous hernias that he took care of. He was very good at explaining everything that took place, breaking it down in to layman's terms so I could understand it all. VERY happy with results. read more

Office is dirty and old looking, fine I can forgive that. Cheesy clippers pictures in waiting room, lame but who cares not important. What is important is the care they provide I've been there 3 times every time they are way over booked and way understaffed it's like the jiffy lube of clinics. I get it, we all like money but dang hire some staff, take less clients, do something. Last time I was there the waiting room was filled, nowhere to sit crying baby, looked like a free clinic. I waited over an hour before I was called in. Do yourself a favor and avoid. read more

Dr. Marcus is the Chief Surgeon at Cedars Marina Hospital. My sister went to their ER with a yet to be diagnosed small bowel obstruction. He personally came to the ER, considered her symptoms and predicted her condition and, correctly, it's likely cause. He is knowledgeable, available (important to us), kind and , most importantly, skillful as a surgeon. Followup after discharge was steady and always realistic and reassuring. Recommend him with zero hesitation. read more

My wife and I have nothing but praise for Dr. Marcus. My wife's gallbladder was infected and needed removal as soon as possible. Dr. Marcus and his staff got the surgery set up faster than we expected, and the techniques that he used reflected the latest technology. My wife has MS, but even so, was able to heal quickly, because the size of the incisions was kept to a minimum. read more

My 25 year old son lives in LA and needed a hernia repair. Unfortunately, I (his mom) live 7 hours away from him so I researched dr Marcus and decided to have him perform the surgery. Matt had an exceptional experience with dr. Marcus. He explained everything on matt's level and was very reassuring before, during and after the surgery. Dr Marcus has an excellent staff who also made themselves available to us. Dr Marcus was out of network with my insurance but he worked with us. He is excellent. Matt was back to work 4 days after the i inguinal hernia repair and back to surfing exactly 3 weeks after the surgery. Call dr Marcus, you will be so pleased. read more

I was referred to Dr Marcus from my urologist for a hernia repair. He patiently explained all of the various options he offered and showed me videos to help me in making an informed decision. I opted for the Da Vinci method, a method in which he is a renowned expert, and could not be happier. My surgery was yesterday and I feel really good less then 24 hours later. He believes that I will be back on the tennis court in a few days. Amazing result and a great doc with a great bed side manner. I highly recommend Dr Marcus. read more

My daughter had an emergency appendectomy last week. So far, everything seems to have gone well. She is recovering very quickly and Dr. Marcus's surgical expertise is very top notch. Somewhat surprisingly for a surgeon, he has an excellent bedside manner, is patient, and cares about the patient (and family) understanding the procedure and why surgery is necessary. Because of Dr. Marcus's laparoscopic surgery expertise, the surgery was minimally invasive. The MDR office is fine, we don't need cherry wood paneling on the walls; what is more important is medical expertise. Yes, my daughter had to wait 1 hr 20 minutes to see Dr. Marcus on the post-surgery followup visit, but I believe that's because he only has office hours a certain number of weekdays because of his surgery schedule. Would we have preferred a quicker visit? Of course. But, in the end, it's a small price to pay to be able to deal with such a highly skilled doctor. Melissa and Jasmine in the office are also terrific. We consider ourselves very fortunate to have had the benefit of Dr. Marcus's expertise. read more

Dr. Marcus is a wonderful doctor. He is very caring and makes my mom feel very comfortable. I give him the highest recommendation.

I went to Dr. Marcus for a hernia repair surgery about 7 years ago. He does it Laproscopically meaning small incisions and a quick recovery. When I recently had another hernia on my other side, I immediately tried again to get Dr. Marcus. It took my about 4 months of dealing with health insurance hell, but I had surgery with him last week and once again I am expecting a quick recovery. I expect to be mountain biking just 2 weeks after surgery. A great guy and even better - an intelligent and smart surgeon read more

Dr. Marcus is THE BEST!!! Last year I had to have my gallbladder removed and my GP referred me to Dr. Marcus. Last month I had my first routine colonoscopy at 52 and a large, odd shaped polyp was discovered, but could not be removed during the colonoscopy and therefore required surgery. So, almost one year to the date, I was back in the office of Dr. Marcus. He performed both of my surgeries robotically, which I thought was beyond cool! Okay, amazingly skilled surgeon aside... he has a great bedside manner and that is huge to me. He takes the time to explain the procedure and he has a sincere genuineness about him. Lastly, his office staff are awesome. Melissa and Adriana are both professional, organized, and totally on top of it all! For example, I had an insurance issue that required this second surgery to happen asap. I met with Dr. Marcus on Tuesday and my surgery was Friday morning! That's 2.5 days--Melissa and Adriana are the ones who made all that pre-op "stuff" happen in time!! Thank you, Dr. Marcus and staff for taking such great care of me!!!! read more
