My family and I are beyond grateful for Dr. Davidson and his incredible team. From the very beginning, he took my mom's symptoms seriously, listened carefully, and acted quickly. Thanks to Dr. Davidson's thoroughness carefulness and expertise, my mom's colon cancer was discovered early enough for us to move forward with treatment right away. What truly stood out was not only his medical knowledge, but also the compassion and urgency he showed during one of the scariest times in our lives. He took the time to answer every question, explain everything clearly, and make sure we never felt alone or rushed. His entire office and staff were equally amazing -- so kind, responsive, organized, and genuinely caring. Every phone call was returned quickly, appointments and referrals were handled efficiently, and they always made us feel supported. In a stressful situation where timing matters so much, their fast response and coordination meant everything to our family. You can truly tell that Dr. Davidson and his team care deeply about their patients. We will always be thankful for the care, attention, and urgency they showed my mom. I highly recommend this doctor and office to anyone looking for a GI doctor who is compassionate, knowledgeable, efficient, and surrounded by an outstanding team. Coming from a nurse myself I know a good doctor when I see one and this doctor is the BEST! I found him on yelp based off his reviews and of course I did my own research and I was definitely not disappointed instead Im so happy and thankful to have found him and trusted him with my mom!!!! read more

I chose Dr. Davidson based on good reviews, and initially he seemed thorough and personable. The colonoscopy/endoscopy itself went smoothly. My concerns started before the procedure when I was told the anesthesia was not typically covered by insurance and that I would need to pay $500 out of pocket. I later found out my insurance did cover it. His anesthesiologist just didn't take my insurance. While I should have verified this myself, I felt the information provided was inaccurate. After the procedure, Dr. Davidson called with my results and said everything looked good. I mentioned that I was still experiencing a sour, acidic feeling in my upper stomach, but I felt my concerns were dismissed. When I asked again, his response came across as irritated rather than helpful. I was also disappointed by the billing. I received a charge for an "office visit" for the brief five-minute results call. When I questioned it, I found it was coded as a complex office visit that typically lasts over 45 minutes, which did not seem appropriate. After I challenged the charge, it was removed. Although the procedure itself went well, the follow-up care, communication, and billing experience left me disappointed. I will not be returning. read more

I have been with Dr. Davidson for 10 years and he has always shown me care, kindness, respect and a lot of professionalism. He remembers me year to year and shows me that he enjoys practicing medicine. I highly recommend him! read more

Have you ever seen a doctor personal texting in front of you while on an appointment, and if that's not bad enough, checking his watch? Well this doctor does, I do not recommend him at all! read more

I would not recommend this Dr. I was referred to him and went to the appt where I was given paperwork mislabeled. It had my birthday and first name with some made up last name on the forms, (in spite of the fact that I had filled out paperwork upon arrival)- to schedule a colonoscopy and I was administered a breath test and It was Mislabeled also with some made up last name and my birthday and first name! I took pictures and called the Dr in to tell him why I didn't feel confident in getting my records/ tests, etc. done correctly and would be going elsewhere - I also told him that my insurance should not be billed! I told him that as I sat waiting to speak with him again I had started reading his reviews and apparently his office's incompetence is not just a single occurrence. He was angry but this did not instill confidence. I reported this to my referring Cardiologist. read more

I emailed the office and requested an appointment for a time sensitive issue. I indicated I was available to schedule an appointment in the following week. Since I was a new patient, I figured I would be very fortunate if the office could see me in a week. The office called me the next morning after my email. The receptionist was so kind and professional. She advised she would talk with Dr. Davidson and call me back. She called me back within an hour and advised that Dr. Davidson could see me in 30 minutes! I arrived at the office, the staff was very pleasant, kind and professional. Dr. Davidson was very personable, professional and resolved all my issues. I am a first time patient yet Dr. Davidson and his team treated me with 1st class care. Thank you all very much. read more

The best Dr and staff I've ever dealt with. Professionals that truly care. Thank you for taking care of me. Me and my family will always be going here for our digestive care. read more

Dr. Davidson is an extremely personable and knowledgeable individual. He is extremely transparent, often called me to ask how I was doing and to update me personally on my test results. His staff is the same way-- they are ready at a moments notice and will call/text back super quickly. Dr. Davidson and his team have significantly improved my quality of life. read more

Doctor Davison is a great Doctor i am a living testimony he believes in helping his patients to get better at all times thank you Doctor!from mr Whittaker. read more

There are no words to describe how amazing Dr. Mark Davidson and his staff are. If I could give them 7 stars I would! I've been struggling with GI symptoms for months now and have seen 2 other GI doctors (both at UCLA) and wasn't getting any better. I constantly was misdiagnosed, rushed into prescription meds I didn't need and left feeling worst. Dr. Mark Davidson really takes the time to understand your history, ongoing symptoms and puts together a very clear plan to action to help you get better. I did so much research on my symptoms and he quickly validated all of my concerns and made it very clear why I have SIBO and what treatment plan would work best. Prior to taking any antibiotics, I tried the herbal path for a month before to to see if I could feel better without prescription drugs. It clearly wasn't enough and he explained why it's the appropriate time to switch to antibiotics. Within the first week of taking antibiotics I felt 120% better than I have in the last year! No more bloating, heart burn, fatigue, weight gain, headaches etc. I haven't felt this relieved in a year! Dr. Davidson and his staff (Julie) checked in on me weekly to see how I was progressing. After I completed the antibiotics, we reconnected to discuss next steps. He provided 3 options (2 medicinal one herbal) and let me choose based on my comfort and explained the pros and cons of each option. It's SO rare to find a doctor who is this detail oriented and wants to take the time to educate you before pushing you into a category and prescribing meds. I am so grateful for his help and would recommend him to anyone with GI issues. If you have SIBO Dr. Davidson is your doctor! If you're unsure what's happening, Dr. Davidson is your doctor. Last but not least, their communication is superb. They use a text/email portal which makes it really easy to contact them. Anytime I had a question I could just text the number they gave me and I would get a response within an hour, which is never the case with most doctors. Thank you Julie for being so helpful and responsive. read more

Dr. Davidson is one of the kindest, most professional doctors I've ever been to. He was very thorough with his treatment plan and always explained the rationale behind what he was suggesting in a way that made sense (instead of just throwing medical jargon at you like some other doctors do). His bedside manner was fantastic. He has a way of making you feel comfortable by telling a timely joke and talking you through the entire process step by step. His diagnosis was on point from the first time I saw him and his carefully curated treatment plan led me to a full recovery. 10/10. Would recommend to a friend. Not to mention, his staff are some of the most compassionate folks I've ever met in a medical facility. Thank you to Julie, Jamie, and the rest of the crew for making me feel so at home in your office. read more

I was referred here by my primary physician. I called to make An appointment, surprisingly they had an appointment the next day which I didn't expect. I scheduled my appointment. The day of I called just to confirm and ensure that they had received my file from my primary physician. They had not. So I called my primary to make sure they sentlong story short my doctor said he couldn't send it until next week which was fine I didn't expect such a quick turn around. I got off the phone and called doctor Davidson's office and explained to Julie what my doctor has explained, and I asked her if I should just come in next week when all my file was ready so I wouldn't waste their time or mine. She said no to come on in anyway that the doctor still wants to do a consultation anyway ( in my head I was thinking it's better to do a consultation with my file that has all my tests done.) I arrived. I get to the front everyone's so busy doing something no one really to greet and no sign in I stood at the counter for 5 loooong minutes until I was acknowledged. Finally, Julie comes over and says I called your doctor and they still have not faxed anything. I explained to her the same conversation we had over the phone... that they did not have my file on hand and she still told me to come.... there was an awkward silence. And she said I'm still on hold. I replied with" okay doe what am I doing because over the phone I told you that they didn't have my file and won't until next week and I didn't want to drive all the way down here to waste our time. " She got back on the phone and front desk from my primary told her they can send over some items but it was very minimal info. She tried to brush off and blame my primary for mistakes that were made here I have been going to my primary for years, and I have NEVER had an issue with the doctor even then the front desk admins! They all have been really helpful!!!! read more

I was happy at first until billing started cheating me, Blueshield told me that Dr. Davidson committed fraud by double, triple billing me, on a upper gi and endoscopy I had the same day. Blueshield told me "don't worry thats why we are here for for this not to happen." So instead of charging me for upper gi and endoscopy they charged me like if it happened a different day with all the charges included like anestesiogist facility surgery center to reserve for procedure etc... doubled. Originally Davidson office was shady in giving me costs before procedure, they just could not tell me how much this was going to cost which is mind blowing to me but they gave me a range ; then I started to see bills arriving like $18000 and many others even 7months after procedure I still see bills popping up from nowhere and no one has a clear explain about what this is, its not always showing in Blueshild claims which I complained about it, and everybody is confused by the mess. I feel I paid more than once for some of the stuff and you can imaging the range they quoted me was Bull@t !!! So I fired Davidson ; if I cannot trust him with bills I cannot trust him with my health for sure, god knows what else is happening. I used to come to the office and someone was always in room with Davidson some students and he never ONCE had the courtesy to ask if it was ok I take my cloths off in front of other people ; if it was ok for him to bring other people in the room with him to check me. I found it to be unprofessional offensive, despicable - Last none of the claims I see in Blueshield are showing my $35 copay that I already paid every time I come in. This doctor is so bad that he used publicly my first and last name to criticize my review which is a major fault with the board of médecine as you have to respect client privacy, I just realized about it and made Yelp remove it. Davidson is lucky I am not getting after him with a complaint to the board!!! I don't want to be that low so I'm leaving it alone. read more

IF YOU HAVE SIBO THIS IS YOUR GUY!!!!! I have suffered from this malady for 4 years until I was fortunate enough to get to see him with my new insurance. I brought him a copy of my SIBO test from my old doc and he prescirbed the medicine I had needed for years right away. I ended up getting a relapse and I was aboe to get a second round of treatment! Now I am on a preventative treatment and I have a 90% reduction in symptoms. If I stick to the diet I am sure I will be healed in about a year or so. ****A NOTE TO ALL PEOPLE CONCERNED ABOUT PAYMENTS INSURANCE AND BILLING!!!!***** I did not have any issues in this area. Dr. Mark informed me of every possible price on testing and it is MY respnsibility to contact my insurance company BEFORE getting testing/procedure done. I found him to have the upmost integrity in this area. Remember insurance policies is up to the client. Everyone's plans, dedictible, and coverage is different and he is a specialist in Berverly Hills! He had people coming from around to the world to get treated and for SIBO is the best hands down. read more

I want thank Doctor Davidson for helping me today I love the warm welcome you all gave me. The Doctor was so nice to me. He listened to my complaint and help me set a plan for my treatment. I felt very happy walking out. Love you all very much . Very nice Doctor. Shalini L Sharma read more

I was referred to Dr. Mark M. Davidson by my primary care physician, and I couldn't be happier. Dr. Davidson is one of the most professional, detail oriented doctors I've ever experienced. Pure professionalism from start to finish, it is rare to find this level of patient care in the 21st century. I couldn't recommend him more, I only wish I could give him and his staff 10 Stars! read more

If I could leave a negative I would If your planning on going to this office think second. He is so busy never called back on the EMERGENCY line when we called before office hours. My father was feeling sick and we wanted to know what to do. Important tests he doesn't call you back. Even if you call 20 times. Terrrible! We finally just had to call 911 because he never called on the emergency line when we left a message. read more

I saw Dr. Davidson for a colonoscopy and I would highly recommend him for this specific procedure and as a gastroenterologist in general. His support staff, both at his office and in the surgical center, were superb, genial and efficient. I was attended to with dispatch at both locations. He is a good listener, and he takes whatever time is necessary to answer all questions and to explain everything, until he is convinced that you are an informed patient. He is a caring, competent and trustworthy physician. If you choose him, you will never second guess that decision. read more

Dr. Davidson and his staff are consummate professionals. This is my second time seeing him for a procedure, and minus the awful devil juice for prep , his office made it a breeze. I had the first appointment of the day and I was literally in and done with a colonoscopy in 90 minutes. I encourage you to get the early appointment so you don't have to fast into the day. He's a very well regarded doctor and he actually has a sense of humor if you want to make a joke. You will get reminders for your appointment by text and email, and everything is quite organized. If you have to have someone look at your colon or your esophagus, this just might be your guy. read more

My surgeon suggested I see Dr. Davidson after my colon resection. He has been very helpful with practical suggestions as far as diet and strategies to manage my divertiulitis and tendency toward frequent painful impactions.. He introduced me to FODMAP! which seems to diminish my symptoms. I would recommend Dr. DAVIDSON without reservation. read more

Mark Davidson, MD - Patient - Internal Medicine Near Me - West Hollywood, California

Dr Davidson is an excellent gastrointerologist! I have been to 3 different family doctors since moving to LA 5 years ago, and all of them have referred me to Dr Davidson for my acid reflux issues. They all speak highly of him. Dr Davidson is very knowledgeable, informative, intuitive, and takes your issues seriously. It's also easy to get an appointment with him -- no months-long waits! Dr D has done both my colonoscopy and endoscopy. He and his staff were excellent. For my endoscope, Dr D actually put in my I.V. And it was fast, painless and perfect -- what doctor cares enough to actually do the I.V.??? Dr D has also given me excellent advice on possible hiatal hernia surgery, and has coordinated exceptionally well with my family doctor. He's an excellent doctor who I trust very much! read more

I have been seeing Dr. Davidson for over a decade. He is incredibly bright and insightful with amazing bedside manners. I live in Palm Springs which is over 100 miles away and I drive to see him whenever I have any intestinal issues. His office is friendly and accommodating to my schedule. He comes highly recommended not just from me but from his fellow peers. I recommend him onto you whole heartedly. read more

The staff at Dr. Davidson's was knowledgeable and professional. They understood my need for an appointment and worked with me to find a date. They were quick in responding to additional information from another doctor. Dr. Davidson has a warm demeanor and responsive to my problems. He is very easy to communicate with and listens well. read more

I've been very happy so far with my experiences with Dr. Davidson and the Beverly Hills Center for Digestive Health. I recently had a colonoscopy/endoscopy, which is not something anyone looks forward to. Why was this a positive experience? Let me break it down: 1. I informed the doctor that I am one of those people who has crippling medical anxiety, so any time I have this kind of procedure done I assume the news will be catastrophic. Dr. Davidson patiently talked me off of the ledge several times, which really helped cool down my fears. 2. The instructions I received for preparing for the procedures were thorough and easy to follow. 3. I was treated beautifully at the surgery center where I had the procedure done. No discomfort, and I felt well taken care of the entire time. 4. After the procedure, and in the follow-up visit with the doctor, he was patient and thorough in reviewing my results. 5. The staff at the office are efficient and warm and friendly. I hope I don't have to see a GI very often (!) but if I do, I'll be very comfortable going back to Dr. Davidson. read more

Knowledgeable, respectful, very friendly, and cooperative. Gives quick diagnoses and honest with his answers. I'd definitely visit him if I have a GI issue. read more

I went to see Dr. Davidson about 18 months ago because I was suffering from an undiagnosed intestinal disorder (will leave out the gory details) that had my primary care physician stumped. It took a few different therapies to fix the problem, but Dr. Davidson was perserverent, and for the past 9 months, I've been doing fine -- my guts are in great shape! read more

I came in to see Dr. Davidson after complications related to a surgery from a different doctor. My quality of life was at a point where it couldn't get any worse and I was desperate to see the best person I could find to diagnose my issues. Dr. Davidson had a plan of what tests needed to be done and told me what his suspicions were and what tests he would be ordering each step until he figured things out. A few tests later and a positive diagnosis led to the treatment that for me was absolutely life changing. From constant abdominal pain that wouldn't let me sleep more than a few hours at night to fully cured after a round of medication. I owe so much to Dr. Davidson and his staff. When I felt like my condition was hopeless due to other doctors not being able to figure out what was going on, he came through big time. I would recommend 100% to see him for GI issues any time. read more

After being referred to several different doctors over the years for severe stomach pain ,and getting no relief, I finally just looked online and found Dr Davidson. He was close and his credentials looked good. I made an appointment for the next day which was amazing. He suggested I stop taking Advil and that he do a colonoscopy which he did. But what no other doctor had discovered, he tested for and I was positive. He prescribed 3 drugs and after a week, I feel like a whole new person. I can not even tell you how much this has changed my life. His office staff is friendly and responsive. Just the best doctor I think I have ever seen. Highly recommend to anyone who is suffering with stomach and gastric issues. read more

Charged $150 upon entrance in November, told I would get it right back from insurance. It's february - still fighting for it. Was put on medication that made me have suicidal and manic breakdowns. was told to take two weeks off then try again. Doctor did not believe my symptoms. I tried medicine again and the reaction was even worse. Got a second opinion from a specialist in the field of issue, was told I never should have been put on any medication in the first place that my levels were normal and I had a non issue. non issue, not a disease that needs medication for the rest of my life. This guy is in it for the money. avoid. read more

I went to Dr. Davidson a few years ago for intense stomach pains. After a few visits he recommended a colonoscopy. Firstly he schedules the procedure for an out of network facility despite having my insurance information. I got that changed to a new facility once i researched. After the procedure they sent my biopsy to an out of network lab which resulted in a $5000 lab fee. Luckily my insurance worked with me and agreed to cover the cost stating it wasn't my fault the doctor chose to use an out of network labs. Then I went in for the results, for Dr. Davidson to tell me nothing was wrong and my crippling isolated stomach pain (that I experience about once a quarter) is food allergies. I have now been to a new Dr. who seems to care substantially more about finding out what is going on with my stomach. So I called Dr. Davidson's office to have my paperwork and colonoscopy info faxed to my new doctor and I was told I will be charged $25 for this. I've never had a doctor charge to simple fax/email MY info to a new doctor. Dr. Davidson is out to make a dollar and not to help his patients. read more

Dr. Davidson is a great GI doctor. Unfortunately his office has very disorganized and unethical billing practices. They try to overcharge and have no explanation for charges made. We have spent hours on the phone with several people in his office and they are rude and can provide no explanation. They just want more money without being able to explain why. It's unfortunate that a great doctor has such incompetent staff. If you are going to use Dr. Davidson be aware that you will likely be overcharged and will have to fight with their office to be treated ethically. read more

Dr. Davidson is incredible! I've been dealing with acid reflux off and on for over a decade, taking serious medications like proton pump inhibitors to combat symptoms. After one appointment with Dr. Davidson, he was able to suggest simple lifestyle and dietary changes that completely cured me of my symptoms. Wish I went to him years ago! Thanks, Dr. Davidson! read more

After several other consults, Dr. Davidson was the best GI doctor I have seen. He was very thorough, meticulous, and took time to explain everything clearly and with compassion. His staff was also professional and friendly. I would definitely recommend Dr. Davidson. read more

Update: I am cured !!! Thanks to Dr. Davidson and his lovely staff I am H.plyori free !! Original: Mark Davidson is a great doctor. He has been helping me with my stomach issues. I am so grateful I went to him! He found out I have H.pylori and got my bloodwork done. They actually call and go over your results good or bad which I liked since most doctors never mention to me how my blood work came out. Dr. Davidson was so informative and a great listener. They have an friendly staff. Julie at the front desk has been such a pleasure to speak with and she is accommodating and sweet. Thank you Dr.Davidson and staff. read more

Dr. Davidson is caring, extremely knowledgeable, and passionate about his work! I felt completely comfortable talking to him about my stomach issues and he performed a variety of thorough tests to get to the bottom of things. It turns out I am lactose intolerant but Dr. Davidson had me come back to review all of the lab work and see if I had any questions! I highly recommend him!! read more

I like this guy, no nonsense. He knows his stuff and explains nicely. I went to him originally, for a colonoscopy. He was very detailed in his explanation and very caring. I saw him again for something different and even asked him about my painful finger joints, he smiled and kindly explained that he wasn't a specialist for joints, but he gave me a few tips and ideas including some natural supplements. What do you know my figures are not hurting any more and I'm a happy camper inside and out. Seriously, he is super smart and I'm very grateful. Thank you Dr Davidson. read more

Dr. Davidson is absolutely the best. He's been my doctor for well over a decade now and has ALWAYS been kind, attentive, ON-TIME, thorough, friendly, and genuinely caring. The office runs remarkably smoothly for how busy they are, and I've never had to wait more than a few minutes for an appointment. He isn't going to prescribe you things you don't really need just because you ask for them. Likewise, he won't prescribe you things just because the Pharma reps are pushing them. He will, however, thoroughly assess your situation and give you an appropriate course of action and/or medication. He's seen me through 4 different insurance companies and a slew of maladies, and I wouldn't go to anyone else. read more

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
