Returning patient: Dr. Davidson is one of the best GI doctors in town, PERIOD. Went back to him after I found an issue and his caring, knowledge and kindness impressed me one more time.He is a true blessing and I feel very fortunate that we have him in our corner, again he is the one to see. read more

I needed to schedule a consultation immediately and Dr. Davidson's office was wonderfully accommodating. Dr. Davidson is extremely competent and easy to talk to. Huge recommend here. The opposite of your typical doctor's office/waiting room nightmare! read more

Honestly, this is perhaps the BEST and THOROUGH treatment I have ever had from any physician/specialist. Dr. Davidson was very informative, and he also provided me with clear direction towards improving my overall health. A no brainer for anyone seeking a GI! read more

I went to the emergency room 4 times (3 different hospitals) and urgent care 6 times (4 different ones) before seeing Dr. Davidson. Within 72 hours of meeting him, I was diagnosed (correctly) with gallbladder disease and had it removed. Months of agony, over in moments. Not only is Dr. Davidson an excellent physician and a top notch specialist, but he is patient, kind, and caring. I cannot recommend him highly enough! read more

Dr. Davidson is not only a great and talented physician but a terrific and personable individual. I saw him for the fourth time today because I was experiencing a new gastroenterological issue. My first visit was a referral from my primary care doctor for both a hemorrhoid that was giving me trouble and also because I was overdue for a repeat colonoscopy. He provided me with more than enough guidance and information to make an intelligent decision. My second visit with him was when he performed the colonoscopy at La Peer Surgical Center on Wilshire Blvd. and when I awoke from the procedure he had not only printed instructions for follow-up care, but also provided me with TWO copies of his surgical report including color photos, one for my own records and another for my primary care physician! My third appointment with Dr. Davidson was a follow-up visit after my colonoscopy. My visit with him today was for what I believed to be another hemorrhoidal flare, when in fact it is an anal fissure. He was incredibly gentle while examining me and I was extremely relieved when he informed me about a topical cream he invented himself and has had success with in the past as an alternative to surgical repair. I start applying this formulated cream today and will post my own results at a later date. Dr. Davidson's staff are all very professional and courteous. I'm extremely pleased to have Dr. Davidson as my Gastroenterologist and I highly recommend him. Thanks everyone at Dr. Davidson's office!!! H.R.Reyes, M.S., Ph.D. Addendum 27Aug2013: I neglected to mention that Dr. Davidson's dietary recommendations have made a vast improvement in my overall health. Thanks again Dr. Davidson! Addendum 28Aug2013: Second application of Dr. Davidson's topical cream and so far not only no side effects, but I already feel my fissure is much improved. Thanks again! read more

Avoid this guy. From top to bottom, the operation is poor. Note to doctor: you do not have my permission to reveal anything about my medical condition or me. I note in your responses to other reviews that when a patient complains, you reveal a substantial amount of their medical file online. This is a breach of confidentiality. read more

Dr. Davidson is the best in town if you are looking for a person who literally knows his shit. I went with a problem that I have had for years and he fixed it. Coupled with his knowledge and experience he also has a very good sense of humour which is kind of imperative when you are dealing with this type of doctor. He is also very down to earth. His office staff are also really great. The receptionist is a lovely woman. Katie doctor Davidson's sidekick aka doctors assistant I think they are called in the USA is absolutely lovely and very disarming and manages to put you at ease before seeing the doctor. Not to mention that she is really pretty and if I was any kind of man with balls I would have asked her out on a date but alas I am just a boy trapped in a man's body. Anyway go see Dr. Davidson and his amazing technicolor staff if you looking for one of these types of doctors. I promise you will not be disappointed. read more

Dr. Davidson is the best!!! He is honest, kind and trustworthy. I was originally referred to Dr. Davidson to receive Biofeedback. Dr. Davidson examined me before administering Biofeedback.. thank goodness he did because he determined that Biofeedback wouldn't help my issues and he didn't feel comfortable charging me for something that wouldn't help me. After that day, Dr. Davidson became my Gastroenterologist. His medical suggestions are geared to help the patient and not his pocket. Every test that he ordered brought me 1 step closer to finding out that I suffered from Colonic Inertia. A Colorectal surgeon preformed my surgery and while in the hospital Dr. Davidson just stopped by to see how I was doing. There are more great things I can say about this doctor but you would have to experience his service to understand how kind this doctor is!!! read more

Dr Davidson is the best! An amazing doctor and a very kind person as well! He's my primary doctor and also my gastrointestinal doctor, which is awesome because he can treat any health issue that may arise. He has earned my trust over the past 5 years I've been seeing him and I know I am getting the best treatments for my health. The wonderful staff that works here - especially Julie and Emily- are always super helpful and friendly! The office is in a prime location, close to Cedars Sinai. I'll continue coming here, and highly recommend! read more

Dr. Mark Davidson is a life saver. I have seen other gastrointestinal doctors over the years and none of them was much help. I went to Dr. Davidson because I was in Mexico and picked up a bacteria that was giving me severe stomach trouble. But while there we began talking about my stomach trouble that I have had for years, almost 30 years. He treated the bacteria with drugs and that cleared up wonderfully. We then began to tackle my more chronic stomach trouble. I was forever constipated, had horrible indigestion all the time and burped constantly. I would only get relief on the days that I would develop diarrhea. That would clean my system out some. One gastro doctor I went to once said, "I think you were just poorly potty trained." And did not give me one bit of relief. Dr. Davidson ordered an x-ray of my stomach and intestines. Well I was impacted horribly. Full of it. He gave me a prescription and now I am doing great. I don't have the indigestion, not burping all the time. No more alka-seltzer, anti-acid drugs constantly. It has relieved years of problems. Wish I had discovered him earlier on. His staff is great and are always very kind and helpful when I call. I highly recommend Dr. Mark Davidson. read more

I knew better. But I still read the newspaper .....in the bathroom. Dr. Davidson fixed me up with this Band and Release thing they have now. Pretty much painless. Glad it's done. I would recommend Dr. Davidson to a friend. Randy read more

I live downtown and called a few places close by and was told wait list was over a month. Called Dr. Davidson and they took me that same week. Took care of me and diagnosed within 2 visits. Did a follow up online due to COVID. All were very easy. Scheduling and dealing with insurance was very easy as the office communicates via txt message/email. read more

Dr. Davidson is very knowledgeable in his field yet extremely humble. During our visit, he was very professional, honest and genuinely cared to address our concerns. Dr. Davidson listened patiently and asked questions that our previous doctors hadn't. I must add that Dr. Davidson is generous with his time and for someone in his position time is money. Lastly, we had a pleasant experience with his staff, Julie in particular. We highly recommend Dr. Davidson! read more

I have been a patient of Dr davidson for a while now. As I get to know him, I get to appreciate him more and more. He practices in a very straight forward manner. His knowledge is very up todate and staff are very nice and professional. Waite time was zero. Strongly recommended. read more

Dr. Davidson and his extremely personable staff/team put me at ease and definitely made me feel like I'm in good hands! Eric P. read more

I would highly Dr. Davidson! My wife became extremely ill with ulcerative colitis about 7 months ago. We didn't know what it was at first, but we knew whatever it was, it was bad. I picked up the phone and called 6 different GI specialist on a Sunday night, pleading with answering machines for a morning appointment for my wife. The receptionist at Dr. Davidson's called me back first thing in the morning, was kind and sympathetic to my plight, and made us an appointment THAT DAY. Every other office refused to see us within 7 days. When we arrived, Dr. Davidson took the time to explain EVERYTHING, answered all of our questions, was extremely patient and honest about my wife condition. He always had a positive attitude and never made my wife feel uncomfortable (which was the most important part for both of us). He explained all options for treatment and never pressured us into any of them. He even offered to see us at another office when our insurance changed and was no longer accepted at the Cedars office. Over the course of 7 months, he performed her colonoscopy, has taken countless unscheduled calls from my wife, and has proven to be an expert in his craft. read more

I was lucky enough to be referred from another friend and patient of Dr. Davidson's. I have had GI Issues for several years now, and Dr. Davidson has been amazing. He finally figured out some key issues, and has been extremely empathetic, and is really trying to think outside the box. Although, we are still trying to figure out how to solve them, he has been so gracious to get me in for same day appts when I have been sicker than usual, and has referred me to the right specialists when necessary. I can't say enough good things about this physican. read more

I wish I could leave Zero stars!! Sure, the doctor is friendly and nice which is great but this facility doesn't care about your HEALTH!!!!!!I had blood work done which Dr. Davidson recommended and guess what, I had 2 deficiencies: thyroid and iron! No one called to tell me anything. My symptoms got worse and didn't hear a word for the doctor. THEY DO NOT CARE ABOUT YOUR HEALTH!! I waited over 45mins to see the doctor (they double book patients) and I don't think the Doctor even looked at my results! My new doctor had my results faxed over and properly treated me that day! They also had me do more detailed blood work and called me with 24 hours with a course of action plan, which is exactly how medical professional should be!! This place is all about money, they don't care about the patient! Worst experience ever. DO NOT TRUST THIS PLACE!! What if it was something more serious! Don't take the chance, find a doctor that cares about your health not about the money!! Never again! read more

I have been seeing Dr. D for 8 years. I started with him when I was concerned about digestive issues and he has consistently been attentive and knowledgeable to my issues and my concerns. He treats me as an entire patient, not just a symptom, addressing concerns I might have in advance, preventative care, and genetic issues. I recommend him very highly! read more

I absolutely Love Dr Mark Davidson ! This man is the one to see , kind , compassionate , a sense of humor and a Great great doctor . He has been an incredible advocate for my spouse who is extremely ill and has been so proactive in his care ! I really can't say enough good things about Dr Davidson A true blessing and I feel very very fortunate that we have him in our corner , Again he s the one to see ! read more

This was my first visit to Dr. Davidson office His staff is polite, they explain to me what, when & where about my procedures. Then my follow up appointment, Dr talk to me about things I need to do to prevent future problems. Dr Davidson and staff are the Best in Beverly Hills I will refer Dr Davidson to my Family and Friends. read more

Dr Davidson and the team took great care of me. Can't recommend enough. He's thorough, friendly, informative and efficient. The staff is helpful and responsive making it easy to get appointments and complete procedures. read more

Dr. Davidson diagnosed me after 20 years of doctors visits. I couldn't be happier to finally know what my condition was and receive the correct treatment. Thank you, Dr. Davidson read more

Dr. Davidson is a firm pass. He does not have the best personality which come off a bit rude. I waited 5 hours after my scheduled colonoscopy, and he could not spare a minute to talk to me while I waited on the table. He was on the phone the entire time. I felt horrible after the procedure, and this is my 5th time getting one. I won't be back. FYI - his receptionist, Alba is rude and does not respond to pharmacies to get refills. Go elsewhere! read more

Dr.Davidson, is warm, extensively thorough & very caring because he's definitely a patient's Advocate! He wants what is best for you, in his office you're not just a number. His staff is outstanding #ELBA and the rest of the staff and there's never a long waiting time no matter when I go. I came to him, recently with a second opinion from my gynecologist and he very promptly helped me make the correct decision between medical need and cosmetic need, if you will. He's very much for the patient he believes in taking care of yourself, getting good sleep, eating right. I like how he listens, and he does incredible amount of follow-up calls. He personally calls after my blood test, to go over them with me. I never feel rushed over the phone or in the office. He is so worth the drive from Burbank, and in my opinion no better care than Cedar-Sinai. read more

Dr. Davidson and his whole team were truly excellent to work with -- completely professional, efficient and caring. Despite the good results from my colonoscopy, Dr. Davidson took the time to talk me through them and explained how to interpret them. Will definitely refer friends and family here! read more

Just had a colonoscopy performed by Dr Davidson. Understandably, i had anxiety going in, but the sensitivity and professionalism from the staff starting with the Registration Clerks, to the RNs, to the anesthesiologist (David Choi MD), to Dr Davidson really put me at ease. Also, no pain/discomfort post-operatively, no ill effects from anesthesia (propofol). To clarify, procedures are done at La Peer Surgery Center on Wilshire Blvd. Doctor has office in professional building at Cedars-Sinai. read more

In response to you, we were already separated when I saw you, it was amicable, and we are still married. In my opinion you are grasping at straws for your questionable activities and my marriage, it's a good thing for me I keep all the documentation to show what you did, as for life I am quite happy, I don't screw over people, defraud people. This is a case of KARMA! I thought doctors take an Oath save lives, did you take one? In looking at other reviews, it appears I am not the only one who experienced this, I don't care about this situation in a public forum, I am happy that it is, so that others can see. I still feel the same, I stand by what you I said, can you prove that you did not do what you did? I can, I still have the claims, all of them, I would gladly show them. I assumed you were a Doctor, not a marriage counselor, I am soo happy that others can see what you have done, and as I can see, some of your most recent reviews are not that great, and in this great Country we are entitled to our own opinions- as I said I would rather go into the light than to have you do anything for me, I don't trust you at all, I hope you have a nice life and wish you peace and hope you can live with some of the things that you have done..........It's a good thing for me, you said what you said, a light bulb came on, and I really know what happened during that time! read more

If go to this office be aware that their number one motive is money & not your health care. they will try to charge you cash rates higher than insurance allowed. For example yesterday i was unaware that i was out of network because no one told me until after i fasted and prepared for a procedure. At ucla they were in network it would have cost me just a co pay $40 & the doctor would have received $294.66 for doing the same procedure that by the way dr davidson was trying to have a low level nurse do without even a doctor onsite. This office requested i give them $400 cash & would have still received 50% from my insurance company. I asked to negotiate since i was not informed and had prepared my body for the test. read more

I am a fairly young guy (still under 40) so I can't believe I am writing a review for a gastroenterologist, but here we are. My symptoms started very gradually about 2 years ago, nothing major but it got progressively worse. I checked for GI doctors after seeing a primary doctor and Dr. Davidson was in-network with my insurance company (BCBS of Illinois). From my very first appointment, I knew this was a doctor I would enjoy working with. He was smart, good bedside manner, not an alarmist, and his staff is quite competent and congenial. Along with my allergist, we worked through several elimination diets, and when I started losing too much weight, we went for the colonoscopy/endoscopy without hesitation. Thankfully that did not show anything and I had already met my deductible for the year, so wasn't a major drain on my wallet. I will say that Dr. Davidson is sensitive to that. As part of my treatment, I had to go on an antibiotic that was incredibly expensive. He said that it was my choice and we could work around that if we needed to or if I didn't want to go on antibiotics. Turned out not to be a problem as it was almost entirely covered by my insurance and I paid only $55. We have come up with a diagnosis for me and thankfully none of the "baddies" are involved. My treatment will consist of diet modification and gradually reintroducing foods to see if my symptoms come back. Dr. Davidson has been very responsive to my inquiries and has really served as more of a coach through this issue. Again, thankfully, we were able to rule out any major issues (thorough history taking and the colonoscopy). Elba and Katirna have been great every time I have been in the office and very helpful with any of my questions. I highly recommend Dr. Davidson and his staff, so much so that I am sending my husband there for his colonoscopy! read more

Unfortunately I have to update my initial 4-star review with a 1 star review. Solely because Dr. Davidson has decided to be one of those physicians who no longer accepts any individual plans only group plans. I was a patient of his for 10 years during which he accepted almost every halfway decent health plan. Though I have a platinum plan from Blue of California that is costing me nearly $800 and month and is not subsidized I was turned away with the comment "We no longer accept Obamacare Plans". Of course mine isn't one its simply not an employer sponsored but an individual plan. However, many physicians are now refusing to accept them. In part because they don't understand the Affordable Health Care Act but mostly because individual plans generally pay a little less to physicians than group plans do. So it doesn't take the reactionaries in this country to repeal the AFHA just greedy physicians and insurance companies many of which are getting out of the business of individual plans completely. SAD! read more

I was able to get an appointment quickly and I didn't have to wait at all on the day of my appointment in the waiting room. The doctor was kind, thorough and communicated with me well. read more

Huh? What? Really? That is what I thought when I read the review posted by "Matt S". Interestingly, enough "Matt S" only has 1 review, so you do the math... Dr. Davidson has the cold nature & impatience of a teenage girl from Orange County, with the "You are inconveniencing me" attitude that is found when watching Kate Gosselin talk to her kids... He would not even take the time to let me explain my problem, constantly interrupting me, when I tried. The smack-in-the-face was his continued yawning whenever I would ask for his interpretation of my lab work & test procedures... No wonder I was able to get an appointment with this specialist the next day. read more

BUYER BEWARE this Doctor is all about the money prior to getting my colonoscopy i called my insurance company for a doctor in my ppo network got davidsons name called the office and asked both my insurance company and the office if there would be any out of pocket costs besides my $50 copay was told by both no. After my first appt. I was told that i would need to pay$400 to tower (which davidson owns) for the anestisisa that is not covered not happy about it but paid called my insurance they said it is covered after my 45 min procedure my insurance paid $16,000 s for was asked to go back to the office so dr could ask me to give him 5 stars on yelp and paid another $50 a month later i get another bill from tower $400 i refuse to pay telling the office to bring this to the dr' s attention which they did and was told i need to pay this its my deductible my insurance co. Told me that the procedure was covered 100% and this dr has had numerous complaints and now is no longer in the network he must really need that $400 this office is a scam and i would not reccomend it and will do everything i could do to let as many people as i can not to use this dishonest man. read more

Extremely Arrogant unknowledgable, un informative and uncaring "Dr". I went to him for Hep C. He....liked the more expensive drugs...3 months worth, OK...but after 2 ...very hard months...he's nowhere. He abandoned my 3 month treatment after 2 months...without a word. Just stopped returning calls....oh ...he is not apart of Cedars, he just rents an office there! STAY AWAY!!!! A very good example of his professionalism....is his rant below....which has been removed AFTER he posted my personal info....again he is NOT on staff at Cedars read more

He is the most amazing, knowledgeable and caring Doctor and human being!!! I highly recommend Dr. Davidson. I've been having severe heart burn and burning abdominal pain to a point where I couldn't sleep at nights and my life was becoming miserable. So i went and visited Dr. Davidson. He properly explained to me what i could potentially have (Acid Reflux) and suggested few diets. But since he realized I'm emotionally ill from my problem he booked me for Endoscopy right away. Two days after the procedure he personally phoned me himself to tell me the good news that im ok and my problem is nothing life threatening (GERD-- which i believe is acid reflux). He's put me on medication and a strict diet, and i have now got back to my normal life and slowly recovering. Im just so glad i went to him, i would definitely HIGHLY recommend him!!! read more

I first met Dr. Davidson when I accompanied my father to his gastroenterology consultation. Dr. Davidson was referred to my father by his primary care physician. My father was anxious to undergo colonoscopy as it was his first time. The appointment was made in timely fashion and the front staff were professional. Dr. Davidson greeted us with a smile and took his time to answer our questions and putting my father at ease. After the visit, my father had a couple of questions and left a message for the office, Dr. Davidson called him back and clarified any concerns my father had regarding colonoscopy. The day of the colonoscopy the staff were professional , the facility was state of the art and the nursing staff were caring. The procedure went smoothly and my father had no pain what so ever. Dr. Davidson found a polyp and resected it. He gave a copy of pictures and procedure report to us at the center and we received a copy of the pathology report the next on the follow up appointment. Two months later I developed severe nausea and abdominal pain and called Dr. Davidson's office. Sonya the front desk staff was helpful in squeezing me in, as the office was booked for a couple of weeks. Dr. Davidson took his time, made the correct diagnosis and got me well quickly. I appreciate his professional, friendly demeanor which is augmented by his sense of humor and ethics. He is highly recommended. read more

First time colonoscopy patient. Every part of the experience, from office visits before and after to insurance considerations to the procedure itself, was handled with courtesy, care and the utmost professionalism. No hesitation in recommending Dr. Davidson and his staff. read more

I had a colonoscopy with Dr. Mark Davidson. He was reffered by our family practitioner and we got more info about him from a few other doctors. He is an excellent doctor, very professional and no wasting of time. If you have any questions, he answers patiently and to the point. The day of my procedure, I had to wait 15-20 minutes after my scheduled time, but I understand that it is very normal and important that he does not rush to finish one procedure after another. I appreciate your professional care and kindness. And I just scheduled my husband's procedure. Regards, S. N. read more

I'll make this short and sweet. Was referred to Dr. Davidson with troubling longterm symptoms. Found him to be impatient, condescending, arrogant. Couldn't be bothered with (very reasonable) questions about my case/care. Finally referred me to Cedars for extensive tests. When test results were sent back to his office, he completely ABANDONED me. Ignored THREE calls while I sat, nervously awaiting my test results. I finally had to make an appointment at Cedars (and pay out of network) just to get my results. To this day, I have never heard back from the doctor or his staff. Los Angeles gastro doctors are about as hard to find as chocolate shops in Switzerland. Do yourself a favor and go elsewhere. read more
