Excellence and Professionalism.I highly recommend Peter M Rosenberg,MD. The office staff is extremely proficient,no wait time and easy scheduling. read more

Dr. Rosenberg is one of the best doctors I have ever seen! He was polite, knowledgeable, assuring, and professional. Great bedside manner and patient. He took time to listen to me and answer all of my questions. While I wish I was seeing Dr. Rosenberg on different circumstances, I'm more than happy to be under his care. :) Sidenote: I wrote this review in the lobby with only 5%battery left on my iPhone, so you know I was truly impressed and wanted to share! read more

I have been to 7 Gastroenterologists with no answer as to why I was having so much pain, etc. Dr. Rosenberg knew my problem right away and I have been seeing him for over 10 years. He prescribed one medication, Colestipol, and it did the job. I still take it everyday. I stay on top of it by seeing him a few times per year. He is a great listener and he really does care. He's amazing so if you have to wait to get an appointment, just wait, he is so worth it. He is the BEST!!! read more

I was referred to this office by my PCP. I called the office and was greeted by an answering machine. Seriously? Like other reviews, this seems to be a pattern. I will seek another GI Doctor, one whose office staff actually answers the phone. read more

Dr R is by far the best GI dr I've ever met However if you want an appt, you'll have to wait 3-6 months. Sure if it's not urgent, I can wait. However my mom had N emergency. And they still said she had to wait 3 months. Ridiculous. May we see his colleagues? No, they have a policy against that. They have some of the best gate keepers employed. However if you talk to their billing office, they've actually been down in sales in the last couple of years. They blame it on covid. Honestly if they just changed their front office staff, their numbers would go right back up. I'm not the first patient who has had to seek care elsewhere bc I couldn't get an appointment read more

I don't normally make it a habit of rating doctors on Yelp, but having found Dr. Rosenberg BECAUSE of Yelp, I felt it appropriate. Dr. R is my kind of doctor: attentive, informed, not quick to jump to invasive methods of exploration (ahem! and given his specialization, this is mas importante). I can also tell by the way he responds to all of my questions that he is up to date on all the latest. I think ella j. put it beautifully: it is a "real doctor-patient" relationship and you will feel truly heard. Hopefully you won't have to find yourself in a specialist's office, but if you do, you won't go wrong with Dr. Rosenberg. read more

I have been a patient of Dr. Rosenberg for many years. He is a great doctor but I am considering switching to another GI doctor. It is impossible to schedule for an appointment because no one answers the phone, It doesn't matter what time you call because you will be put on hold and then it will hang up on you. If you leave a message, no one bothers to return your call. Why can't the front office staff pick up the phone? They don't seem to be busy because they are always chatting or playing on their cell phones. read more

Dr. Rosenberg and staff are the absolute best. He is one of the sweetest and most informative doctors out there. He takes his time with you, doesn't make you feel rushed and provides optimal care. Highly recommended and five stars!!! The ladies/nurses are all helpful and kind as well. They provide great communication with patient and doctor and are on top of their game. Thank you for all your care. read more

Somehow, Dr. Rosenberg makes me look forward to my colonoscopy. He's thorough, caring, approachable, and takes time -- even in a busy clinical setting -- to set his patients at ease and answer questions. True, scheduling with his office is quite daunting, and hopefully that will iron out when COVID protocols are over. read more

Scheduling here is like waiting for Trumps impeachment, seems like it would be easy but you really never see anything happen. Even after the 60 minutes interview. Seems like they are more corporate than you'd want your doctor to be. read more

I have been a patient of Dr. Rosenberg for over 13 years. He is a very caring, knowledgeable and patient, I would recommend him to any friend or family member. The staff is very nice and efficient as well. I have nothing negative to say about this practice. Very Satisfied patient :-) read more

I've seen Dr. Rosenberg 3 maybe 4 times. I really, really appreciate his friendly and engaging personality. He's easy to talk to, he has a sense of humor. He's very gentle and takes time to explain everything. I've never seen him and felt he was in a rush or a hurry. One of his nurses at the Pasadena Endoscopy Center said, "He makes smart decisions". I was impressed by that. His office staff? Certainly there is room for improvement. They could not find any evidence that I had seen him before even though I had at least twice! That was troubling. Other than that though, I recommend him. read more

Very professional and courteous. I'm a young guy and he didn't believe that I needed a colonoscopy but after some tests and family history he booked the appt. Thanks God I did it because it turns out I had precancerous polyps on my colon. I've had three colonoscopys and this was one of the easiest experiences. The Pasadena endoscopy center was easy to deal with and Dr Rosenberg was easy going and very knowledgeable. I'll be back here every five years for the foreseeable future. read more

Dr. Rosenberg is a wonderful doctor. He has a wonderful, warm personality and puts his patients at ease quickly. He has helped me so much in the 5 years I have been seeing him. He is the BEST. read more

I have been a patient of Dr. Rosenberg's for several years and have in the past found him to be a caring and helpful doctor. I no longer have that opinion. It is nearly impossible to see him when you need him, and, curiously, when he is not available I have been told that I can't see any of the other doctors in his practice. In March I called to make an appointment for stomach pains. His front office said the next available appointment would be in August. I said I needed to see him or another doctor in the office sooner.The clerk said I couldn't seen any of the other doctors. She did say I could contact Dr. Rosenberg through the patient portal and have concerns addressed in that manner. I sent a message through the portal on March 30. Today is April 10 and I haven't received a response. If he thinks this is a good way to conduct his practice I'm sure he has other patients with more patience than me. Good for him. read more

I travel from Palm Desert to see Dr. Rosenberg. Enough said! I couldn't survive without him, he's my lifesaver.Be kind to his office staff as they work for 6 Drs. read more

Peter M Rosenberg, MD - Me - Gastroenterologist Near Me - Pasadena, California

This review is based only on the office itself, the receptionist, and the general practice, not Dr. Rosenberg's personality or medical efficacy as a gastroenterologist. I was very much looking forward to having Dr. Rosenberg as my new gastroenterologist after moving from Chicago to Pasadena. However, the process of trying to get a new patient appointment with him was a nightmare. I called on a Thursday, left a message with the office voicemail (as no one would answer even though it was 10:00am), and then I never heard back. After a week, I called again - same thing. I left another message, again stating my name and phone number and that I was looking for a new patient appt with Dr. Rosenberg and hadn't hear back in a week since my first call. I received a voicemail that night, which I responded to the following morning - same thing!!! I left another message, and this time I thankfully got a call back within the next 20 minutes. I spoke with the receptionist, who was at first very nice, though she did not apologize for the 1+ weeks of waiting. She got all my information, emergency contact, etc. Then at the very end of the conversation, after wasting a good 15 minutes of my time, she asked me what kind of Anthem BlueCross insurance I have. I responded that I have a PPO, and she asked if the plan had been purchased through the Covered California marketplace. I said yes, and she responded with "Ohhh, we don't take any of THOSE policies." I clarified several times: "You mean even if it is a regular PPO that already existed before 2014?" She simply stated "Yes, we don't accept any plans purchased through Covered California. Especially if your insurance card has the Covered California logo on it, we don't accept it." WTF?? Seriously?? Does their office have a problem with the new insurance exchange system in general? My PPO is the exact same as PPO plans that Anthem has been offering for years, but now suddenly that I purchased it through Covered CA, I'm no longer good enough to be their patient?? And why does their office not think that this is just maybe important enough to 1. State this policy on their website, and 2. Tell new patients this UP FRONT at the beginning of the phone conversation when scheduling a new appointment??? Ridiculous! All of this left a really bad taste in my mouth and made me really angry with the whole process. I'm sorry, Dr. Rosenberg, I'm sure that you personally are a really good doctor, but you need to seriously address this issue with your overall office and practicing partners. When several MILLION people are now getting PAID individual insurance policies through Covered CA (not talking MediCal, but everyday people like me - entrepreneurs, small business owners, students, etc), this is a big issue. And I feel like fellow Yelpers should know this in advance and not have to waste their time as I did. read more

Hesitant to leave a review that could be unfavorable but for someone searching for a new GI, some things are important. I have been a patient of Dr. Rosenberg's office for 20 years. He, himself is a good Dr. Usually caring, usually will spend ample time listening to you, though sometimes (like my last appointment) after paying parking and waiting an hour in the waiting room, spends 5 minutes with you (suggests an OTC item) and says follow up- I could have gotten that same advice from the clerk at CVS.. Call for a follow up and next available is December. A patient should NEVER have to wait 5 plus months to see their Dr.. NEVER!! If a Dr does not have availably, then he has taken on too many patients and time to stop accepting new ones. read more

Finally a doctor that listens and cares about his patients. Very pleased with time spent in diagnosing and exploring all possible causes of symptoms. Great communication skills and not pretentious despite his impressive background. read more

Dr. Rosenberg has been my G. I. physician for the past eight years, and I can recommend him without reservation. He is a good listener with a great "bedside manner". My ulcerative colitis has been in remission because of his treatment and advice, and I have always been able to get an appointment when needed. He has also returned my telephone inquiries promptly. I am totally confident in his medical knowledge and judgement. He's the best. read more

I was sad to have to find a new gastroenterologist when I moved out of LA. Dr. Rosenberg listens, and communicates clearly and sincerely. We had a real doctor-patient relationship! Imagine that! He was very attentive and gave me excellent care. I highly recommend him if you have Crohn's or Ulcerative Colitis. read more

I was initially diagnosed by Jumi Mok, Nurse Practitioner and then Dr. Rosenberg. Dr Rosenberg is a knowledgeable awesome Doctor. He performed an Sigmoidoscopy and was able to determine my condition with a pathology report. The office staff are also very helpful with anything that is needed. Simply, Dr. Rosenberg and staff are the best in the business. DO NOT GO ANYWHERE ELSE. read more

I found him calm and extremely patient. He listens to you and wait until you explain yourself completely regarding your problem. Then after you're done talking, he would tell you what are the appropriate tests needed to be done. Most doctors rather have you come to the office and pay an office visit in order to get an order form but with him I shoot him an email and he would have my test order ready. Every time I send him an email he would respond back on the same day. What A DOCTOR. He is an amazing doctor. I would recommend him to anyone. He is listed on superdoctors.com web as one of the best. read more

I traveled 2 hours just to see Dr. Peter Rosenberg, and he is truly phenomenal, He really listens to his patients and tries very hard to find a solution.. His Office staff were very nice and friendly. I would definitely recommend Dr. Rosenberg to anyone who is having a GI problem. read more

Peter Rosenberg MD was called in to perform surgery to remove a stone from my bile/pancreatic duct using an endoscope. I am very grateful that this highly recommended surgeon was able to perform this operation the day after my gallbladder was removed. When I recovered enough to see what was done, I found that his stitches around the incisions for the endoscopy were perfect and clean. My scars are healing well and I fully expect them to almost disappear in time. Great doctor! Janet H read more

Dr. Rosenberg has performed a colonoscopy twice now, 10 years apart, and an endoscopy just recently. He has always made me feel very comfortable in his capable hands and has shown true concern for me as a patient. He has been very clear in his explanations of what is going on with me and has made the treatment plan very clear and understandable. Besides all this he is a genuinely friendly guy. I recommend him very highly. read more

He sounds like a great doctor, but my experiences echo those of others here: the office has hands-down the worst phone system ever, and if the web site is accurate (which I would know if someone had actually contacted me), it appears that it will take over 3 months just to get an initial consultation. I talked to a family member who recently scheduled his colonoscopy in a different major metropolitan area: he waited 1 week for the initial appointment, then another 2-3 weeks for the procedure. It left me tempted to fly cross-country to get my own procedure done, but I'm sure there are other good doctors in my area. If you're an existing patient, good for you, it sounds like you're in great hands. If you need to find a doctor to take care of you, look elsewhere. read more

This place is a disaster. It took them 3 months just to call me to schedule an appointment after I dropped off my completed paperwork. They finally called me back and left a message to schedule a date. I called them back to book a session...but they never called me back. I left several follow-up messages to no avail. I'm sure Dr. Rosenberg is a competent doctor but if his staff is a reflection of his medical skill then I would avoid this place at all costs. Bullet dodged. read more

The best, kindest and most supportive doctor I've ever had. He ranks right up there with my neurosurgeon who is also not only skilled, but so very helpful in every way. Dr. Rosenberg has helped me gain an almost complete victory in my fight against terrible IBS. I only wish I'd found him sooner. read more

I have been seeing Dr. Rosenberg for almost over 10 years because of my medical issue. He simply is the BEST. All his staff is very responsive including the doctor via patient portal. Being from EHR (electronic health record) industry, I am loving their online portal system. People who are posting negative reviews about the staff should give it another chance just because you will be seeing one of the best doctors. read more

I am a patient of dr Rosenberg for several years, and I highly recommend him, he is the kind of doctor/friend that we patients need, he listen, he is compassionate, he ALWAYS returns calls, the same day, he always make you feel comfortable, he cares about his patients. thanks Dr Rosenberg, you are the best! read more

Dr. Rosenberg is the best. Listens, smart, speaks like a normal person not a scientist. Has a sense of humor as well.

Feel very lucky to have Dr Rosenberg and his staff

Dr, Rosenberg is treating me for a complicated disease which many other specialists I contacted felt was not treatable. I have seen Dr. Rosenberg 10+ times in the 2 1/2 years. He communicates his findings and test results openly in a way I can understand. Not once has he skimmed over problems side effects and anticipated results of treatment. He and his staff have delivered the best medical care, including referrals and advice, I have ever experienced. read more
