Lets make this a bit fun... DR DAVIDSON STOLE MY WIFE'S ESOPHAGUS!!!! (Let me back up a bit to say he actually didn't "steal" it, it's just not there anymore. This is a strange & painful story, but I'll be brief and use as much levity as a missing esophagus could possibly bring to a situation.) Have been a patient of Dr Davidson's for 5 years and it turns out he saved my wife's life. 3 months ago my wife went back to him as she has over the years to find out why her stomach was bothering her. Dr Davidson went through her symptoms (she had no constantly recurring ones) and prescribed Prevacid (to block stomach acid) and said if it still bothered he'd do an EGD - esophagogastroduodenoscopy (hitting you with the impressive big words now - it means a camera down the throat) in a month. My wife, a rather headstrong person, said, "No, I want one now!" She's not good with uncertainty. He did one and took a biopsy of a tiny red spot halfway down. This turned out to be a spot of dysplasia (you have no idea how much you learn when an esophagus is removed!). What the heck is "Dyspalsia?!", I asked. It's when your acid reflux (again, she had no symptoms) from your stomach backs up into your throat and starts to change the lining of esophagus. It's precancerous, and if bad enough WILL become cancer. Well, we were stunned. In perfect health, we thought, we're young! In shape, looking good, and where does this fit in?? Little did we know. Turns out, after another surgeon did a more intensive EGD she had dysplasia everywhere. Prognosis - remove the esophagus. The surgeon told us that she was VERY lucky that Dr. Davidson saw the tiny red spot and took a biopsy since he saw nothing until he used a special blue dye only he has at Cedars-Sinai. If Dr. Davidson hadn't caught that, and he said he's not sure how he did, she would certainly come down with cancer in the next few years. Well, the esophagus was removed and we are fine and moving on. In the meantime, Dr Davidson is a constant source of calm and reassurance. My wife is eating now and I can fill anyone in on any nausea medication if you'd ever like some advice - ask me about a "J-Tube"! Man, I got info on all this stuff! Let me just say, if you have GERD, or acid reflux, CHECK IT OUT. Who knew... In the meantime, we kinda owe Dr Davidson BIGTIME. (By the way, he shaved the goatee and looks much better for it!) read more

I had spinal fusion surgery (ALIF) 18 months ago and immediately after surgery I experienced sever pain in my tailbone/rectum area. Good times there. My surgeon was perplexed by this and I was given Gabapentin. This really had no impact on my pain. I also was prescribed physical therapy and that only seemed to make things worse. I finally sought a second opinion from a USC Keck Dr., who diagnosed me with pudendal neuralgia. I then went to Dr. Mark Davidson for help with this diagnoses. Because my case was a workers comp. case his staff had to help me getting authorization to see Dr. Davidson. I hounded his staff regarding my authorization and they handled it very professionally. Once I finally saw Dr. Davidson he determined my pain was due to the pudendal nerve be aggravated. He prescribed some medication that has helped me greatly. I was able to email him directly and ask a question about the medication he prescribed. This diagnoses involved an exam that was no fun and his demeanor made it bearable. Dr. Davidson has helped me in a big way. Thus..5 STARS. T read more

I have been a patient of Dr. Mark Davidson for several years and I have known few men who possess the level of compassion and caring that he does. He has been more patient with me and my ailments that anyone could have possibly expected. Anyone who has been as sick as I have been (cancer) would understand. Dr. Davidson is an excellent physician and extremely knowledgeable in his field. I routinely put his knowledge to the test with all the Internet research I come up with. He is always cooperative and supportive of his patients in spite of some of the grumpier ones who have little patience. He has the ability to remove the fear from a lay man about medical procedures tactfully. That is very important for me. I have seen his office staff provide support however and whenever needed. I view this as an asset which demonstrates extreme resourcefulness and respect in a very demanding environment. Most importantly, Dr. Davidson's unwavering commitment to his patients exemplifies just who he is. I recommend him to any and all without question. read more

I just got back from an on time, completely stress free colonoscopy procedure with Dr. Davidson. Great office staff that set up the consult and scheduled the procedure. All I was able to arrange to have done in just a week! The Dr. is engaging and clearly explained the procedure and options - and he's worked out great deals with insurance providers to make sure we get this done and aren't prohibited from doing so by some insurance companies making it difficult or costly. I was impressed by the Dr.and the surgical staff today....they made it really comfortable and that's not easy wearing paper gowns and feeling "exposed" to say the least. kind, funny, caring - got my results discussed with the Dr. right afterwards, including nifty pictures. All good to go! The prep wasn't bad either! just follow the office staff instructions and it's like clockwork. I'll thank my General practitioner Bryan Gaudio at Pacific Oaks for the awesome referral too! read more

I have never met any doctor who's loves his job as much as Dr Davidson does. I usually get so nervous going to a doctors office but not with him. He is so kind, caring and I love the fact he loves to joke around! He will take any situation and make light out of it. Most of my past doctors (which I've had quite a few) are too serious which scares me more then anything. I have referred several people to him and they all can't thank me enough, he's helped all of us including me. I developed horrible stomach issues and I didn't even have to tell him anything further, he tested me for H Pylori and I was positive he gave me some meds and now I'm back to normal thank god. I don't want to forget his staff either, everyone in that office has been spectacular! From the minute you enter till the minute you leave it's been nothing but pleasant. Thank you Dr Davidson, Elba and the rest of your wonderful staff. read more

Hi I am a colon therapist here in L.A. @ Universal Flow. And yesterday I had my very first colonoscopy with Dr. Mark Davidson. I am so grateful my holistic practitioner dr. Cherylnn Lee referred him to me, and she was right he is the best. I am happy to have had the opportunity to be in the presence of Dr. Mark Davidson and his team. I thought I would never say this but I had the most pleasant experience ever having a colonoscopy. Hmmm... Dr. Davidson and his staff was amazing, Betty the recovery nurse awesome and the two Anna's. Anna A. and Anna V. so that I wouldn't be confused. Lol! They all made me feel like I was having the best care ever. In each ones presence I felt totally safe. I will be recommending Dr. Davidson to all of my clients, friends and family. If you have to have this procedure done come have the experience that I had. Blessings La Donna read more

Great bedside manner. Dr Davidson is thorough and effective. He cured my wife of a life long digestive problem and it has changed not only the quality of her life but mine as well. He presents himself with confidence and a dry humor that is very comforting and disarming. I went in recently for a colonoscopy. I had one ten years ago for the same procedure but with another doctor. At that time it was a long recovery and I felt sore and uncomfortable for a couple of days. This time, with Dr Davidson, I was in and out in a couple of hours, and had a painless experience with lots of reserve energy to get things for the rest of the day. The staff were ultra friendly and supportive and overall I was treated like royalty and left with a positive experience. I'm highly recommending him to all my friends and associates. read more

Dr. Davidson is an exceptional doctor. In fact, I registered on Yelp just to write this review. I am in LA on a long work assignment and went to see Dr. Davidson rather randomly for a minor routine issue. But he caught a potentially serious condition that should have been caught by my main doctors at two premier university hospitals on the East Coast. Dr. Davidson is exceptionally knowledgeable and comprehensive in his understanding of the field. For example, the reason he found the condition was due to him insisting on the course of action that came out of research findings only about a year ago. In addition, he is supremely pleasant. I enthusiastically recommend him. read more

I saw Dr. Davidson as a new patient for my diagnosis. He was extremely patient while I explained my circumstances and asked lots of questions about my medical history and diagnosis. He took his time answering all of my questions and followed up with me after my appointment. I had been looking for a gastroenterologist to be my regular doctor for my related problems and I feel very lucky that I found Dr. Davidson not to mention his staffs are really great from Jennifer at the front desk to the two medical assistant Lin and Dunia. My overall experience goes beyond the five star rating!! I cannot express my gratitude towards Doctor and his staff!!! Thank you!!!!!!! read more

I have been seeing Dr. Mark Davidson for 3 years as he's treated and managed my ulcerative colitis. I am the kind of patient who likes to have a thorough understanding of the options that are in front of me so I can understand the decision a doctor is making or participate in the decision myself. Dr. Davidson is patient, kind, and let's me be a partner in managing my health, always giving me time to ask all the questions I have and patiently explaining the options until I fully understand the choices. He skillfully navigates the art and science of treating IBDs. When I call his office for refills or other requests and questions, they are prompt and polite. read more

I was a student with doctor Davidson this past year. I have experienced clinical rotations with several private practitioners, and Dr. Davidson was by far the best. I have to say, it was quite refreshing to see that it is possible to run a private practice while practicing good ethical medicine. He always had the patients' best interests in mind. It can be tough to figure out the source of something like abdominal pain, and Dr. Davidson did everything in his power to figure it out and to help his patients feel better. All of his staff are so kind and accommodating as well. I would send all of my loved ones to Dr. Davidson in a heartbeat! read more

I had a great experience with Dr. Mark Davidson and his staff. He is extremely knowledgeable, honest, and takes the time to explain everything in detail about my health and treatment options. He answered all my questions thoroughly and made sure I understood the next steps. His professionalism and compassion truly stand out, making me feel comfortable and well cared for. The office staff is friendly, courteous, and efficient. Scheduling an appointment was easy, and they were very considerate throughout my visit. I highly recommend Dr. Davidson to anyone looking for a skilled and trustworthy doctor. read more

Dr. Davidson is great! He listened to my medical history and performed several diagnostic tests. When the tests came back negative, he treated my chronic constipation symptoms appropriately, which reduced the severity of the abdominal attacks I was having. This allowed me to recognize a pattern which hadn't been apparent before. After a second internal examination, Dr. Davidson referred me to a gynecologist who ultimately diagnosed me with stage IV endometriosis. I can't thank him enough for helping me resolve the horrible abdominal attacks I was having for over 2 years. read more

Outstanding. If you have been told that getting a colonoscopy is a tough experience, then have the procedure handled by Dr. Davidson. From the prep, to the procedure, to the follow up, Dr. Davidson made the process easy, painless, and stress-free. His staff is extremely professional, efficient, and very good at what they do, from the receptionist, to the prep nurse, the anesthesiologist, to the recovery nurse. It's remarkable that the experience was pleasant, given the tales I've heard of having a colonoscopy, and the credit for that goes to Dr. Davidson and his staff. read more

I had a very positive experience with Dr. Davidson. He is an amazing Gastroenterologist with surgery centers in various locations. I have had a chronic illness that no doctor was able to treat. I met with him and he made a quick diagnosis, and treated me with optimum care. Both him and his staff are very friendly and efficient. There was no long wait time like other doctor offices which was a huge plus!!! I recommend Dr. Davidson to anyone that needs or is in search for a great gastroenterologist or other care that requires an internal specialist! read more
