I recently visited Dr. Wei-Chung Chen, a Gastroenterologist, for a follow-up regarding my liver health. Scheduling the appointment was smoothly. Dr. Chen was extremely professional and took the time to thoroughly explain my condition and the potential treatments available.

After my consultation, Dr. Chen outlined a clear treatment plan, which gave me confidence moving forward. One thing that really impressed and moved me was that after every visit, Dr. Chen always personally accompanies patients to the door and kindly explains how to schedule the next appointment or follow-up tests at the front desk. It’s clear that he is not only a highly skilled doctor but also a compassionate and humble person. I feel truly blessed to have found such a wonderful doctor who takes such genuine care of my health.

In my first visit to Dr Chen for abdominal pain and rectum discomfort, he ordered an EGD and sigmoidoscopy. He did polyps removal, biopsy on suspicious areas, and took many pictures of the conditions. Afterward, I felt no discomfort at the throat area at all, which is an indication of the careful passing of the scope through that area. The selection of biopsy sites was very thorough and accurate, as it caught several issues as evident in the pathology report. During the follow up visit, Dr Chen explained the results to me with the pictures and answered my questions, patiently and precisely. He even taught me how to identify the focal erosion in the endoscopic pictures, which is greatly appreciated as I like to learn. He is very professional, knowledgeable, patient, thorough, kind and gentle. He explains the reasons of, but yet firm, on his medical recommendations. I am very glad to have Dr Chen as my gastroenterologist and highly recommend him.

During the whole consultation process, Dr. Chen listened very patiently, carefully and professionally, and explained my condition very carefully, which made me feel at ease. As long as I follow up regularly and adjust my work, rest and diet, I believe my body will improve. My husband has always praised Dr. Chen for being young, steady and polite. I have made an appointment for my husband to see Dr. Chen. We strongly and sincerely recommend Dr. Chen, he is the best and best doctor I have ever seen.

Dr Chen reminded me of my father who was also a Doctor. What I noticed about Dr Chen is that he is a great listener. He listens intently to the patient. He takes the patients observations seriously, and deducts a medical scientific opinion based on evidence which he has seen, along with notes taken from the patient. He is patient and takes time and allows the patient to relax. I was very happy with his care and I would highly recommend him to anyone else who may need his services.

I was referred to Dr. Chen by my OB/GYN for a colonoscopy due to a suspected GI bleeding. My encounter with Dr. Chen and his staff exceeded my expectations. I am a registered nurse, and I’m well informed about routine procedures and experienced when it comes to what safe and exceptional patient care is. Starting with the nurse who checked me in for my procedure as well the receptionist. Very friendly, thorough, and explained the process of what is to be expected when I’m called in by the nurse for my procedure. I wish I could remember names, but my recovery nurse was so personable and sweet. The surgical tech was also very nice. Given how many patients I can imagine come in for GI procedures everyday, Dr. Chen and his staff are very personable, and really make you feel comfortable and well cared for. Dr. Chen has a very kind bedside manner. He never seemed rushed during my appointments and reviews everything in detail. Having a colonoscopy is probably one of the least pleasant things I can imagine however, Dr. Chen and his staff at Insite make it as comfortable as possible.

Several months ago I consulted with Dr. Wei-Chung Chen regarding a spot on my pancreas discovered by way of a Cat Scan. The doctor reviewed my tests and gave me my options. I elected to have an endoscopy in order to obtain a biopsy. The procedure went perfectly and the doctor spent all the time I needed in explaining the results. I found him highly professional. I also treated with another doctor in his group for something else and I give them my highest rating knowing that I was in good hands. We are fortunate to have these excellent physicians at our disposal.

I saw Dr. Chen for the first time a week ago.I chose him based on his education and experience. I was not disappointed, I described the problem I was experiencing. He was able to provide a diagnosis which he backed up with test orders to rule out other possibilities. And he provided a course of treatment to follow which has been successful in treating the problem, He listens and responds to questions, and patient offered information,.he processes details. He is focused on the problem not wasting his or my time chatting, but at the same time open and accessible. He did not have a self important attitude. He is a highly skilled physician, knowledgeable , patient, pleasant to deal with and an experienced clinician. I would and have recommended him to friends.

If you are looking for a doctor who will take your pain seriously I highly recommend Dr. Wei-Chung Chen. I had my first video call appointment with him and it went great in my opinion. I have a hard time explaining myself often, but he did a great job at trying his best to understand my situation. He asked questions and asked for clarification which I really appreciated. He also asked the RIGHT questions and answered all of mine. He even made sure a few times if I had anymore since I didn’t ask that many. He didn’t ignore me at all or brush aside any discomfort or pain I was having. He took me very seriously! As a 20 year old female I have had bad experiences with multiple doctors not caring about me. He also had me feel at ease and comfortable. I will update once I have more experience with him, but I have high trust and hope in him that he will help me figure out what’s wrong. If you going to go first time. I recommend writing down everything you have been experiencing, time frame of those symptoms, medications, and any questions you might have. Edit: He diagnosed me after the procedures and I felt much better because of prescribed medicine ever since.

Dr.Wei-Chung Chen, MD who specializes in gastroenterology and lIver disease at InSite Digestive Health and I met on January 28, 2020. . He studied under Dr. Robert R. Selby at Keck who had been the Lead Physician in treating my pancreatic cyst. His mentor was Dr. Jacques Van Dam who performed most of my endoscopies. I feel I am in good hands. We have scheduled an Ultrasound with needle biopsy in two days. I'll have the opportunity to rate Dr. Chen again after that procedure.

I had an appointment for an upper Gi with Dr. Wei-Chung Chen. I was very pleased with Dr. Chen, he was very informative and took time to discuss his findings of my procedure immediately after the upper G I while I was still in the procedure room. I appreciate this because you will get written information and pictures from the procedure later and before you leave the diagnostic procedure center. Having his discussion and information before the info and pictures puts you at ease. About two weeks after the procedure you will have a follow up visit to discuss any biopsy information and/or medical recommendations. In this follow up meeting Dr Chen was very informative and took his time to have meaningful two way conversation. I appreciate his professionalism, communication and time he took with me. All my doctors have retired in the last three years. Dr. Chen is young and will be practicing medicine for many more years. He will be available for your next visit or ongoing care.

Dr. Chen was my gastroenterologist when i went to the ER for a bleeding ulcer. He cauterized the source of the bleeding and explained everything he found in my endoscopy carefully and made sure i understood. He was on top of my follow up care. He called me to make sure i got my medication correctly when my insurance didn't cover the medicine he prescribed and also cleared up the incorrect prescription that the ER doctor prescribed incorrectly. He has been a great doctor, always knowledgeable, professional, and attentive. Would recommend to everybody.

Dr Wei-Chung Chen was empathetic, listened to all the details of the symptoms and illness I had been coping with for a couple of years. He said he could help me with “regular” GI issues, but that for a specific set of symptoms I would need to see GI Specialist “Specialist.” He provided three names and explained that his staff would send my medical records et al to the first (preferred) Specialist. That doctor would review my records and determine whether to accept me as his patient or not. I lucked out and the Specialist that Dr Chen preferred accepted me! I continue to see Dr Chen for other “normal” GI issues. I HIGHLY recommend Dr Wei-Chung Chen and the other GI doctors at inSite Digestive at 50 Alessandro Pl, Pasadena !!!

He remembers your face and what you are there for , many doctors do not take the time to listen to their patients because of the high demand but he does .
