Had umbilical hernia surgery 35 yrs ago that failed. Dr had me lose 25lb before repairing. Took my 3 mths but additional significant benefits including my A1c type2 diabetes dropped to 6.0 and the pain in my right knee torn meniscus much better carrying less weight. Excellent surgeon and a straight shooter...tells you like it is. Highly recommend. read more

This guy is an artist. Doing surgery with dr wang is a great way to go when considering top quality care. Highly recommend this surgeon for all your general surgical needs. read more

Dr. Wang is an extremely skilled surgeon who shows genuine care for his patients. He saved my mother's life with an incredibly complex procedure and stopped in every day to check on her after surgery. He is diligent and thorough about follow-up, and even answered the phone himself when there was a complication after surgery. He is a great surgeon and I would recommend him without reservation. read more

I can't say enough good things about Dr. Wang. My husband had a horrific experience after a hernia repair from another surgeon. Everything that could go wrong did. My husband had perforated bowels and 2 enterocutaneous fistulas that was making our lives and his health a literal medical nightmare. I honestly didn't know if he was going to make it. With the recommendation of several friends we reached out to Dr. Wang. Dr. Wang took an extremely complicated case and put my husband back together. Literally. I truly believe my husband would not be here if it weren't for Dr. Wang. He should get 50 stars. He really is the best surgeon read more

Dr Wang is a wonderful surgeon. He is very kind and helpful. He ensured I had a smooth prep, surgery and follow up. I am so glad to choose him to be my surgeon. Dr Wang provides excellent treatment. His curiosity and investigative mind and ability to connect will ease your mind and you will definitely know where you stand immediately and what next steps look like. He never fails to properly informed you before he starts with any procedure to make sure that you are educated before making any decisions. He also talks to you in such personal level. Never once he speaks in a superior tone. Even though we all know he's the smartest one in the room. lol. I would definitely recommend him to anyone. It's very rare to find surgeon that combines personal touches and also outstanding quality of medical care. read more

I needed an emergency colectomy and glad I had Dr.Wang to perform the surgery. Several of the hospital staff staff well as non hospital staff professionals gave him the highest marks. He is very straightforward in his diagnosis and is clearly a very good surgeon. He is also quite upbeat and has energy I respect. I recovered from the surgery quickly and well. Office experience: Be prepared for a wait. He has far fewer office hours than surgery hours, to be expected with an emergency multi specialty surgeon. Staff will tell you about how long the wait will be, so prepare not to have a tight personal schedule. read more

Doctor Peter C. Wang commitment, personal touches and quality of medical care is outstanding. He's highly skilled and isa very compassionate surgeon with high knowledge, skills and professionalism. He's very engaged and he always makes sure to answer all questions, that I have had and that my recovery has gone so great as anticipated. I felt very safe and comfortable having him do my surgeries and I can highly recommend Doctor Peter C. Wang as your surgeon, he's the best! read more

I had a diverticular fistula and sigmoid resection in November. Dr. Wang was highly recommended to me by a coworker, who had a similar experience and had gone to Dr. Wang for himself and his children. Clearly, that last part goes a long way. My procedure was complicated with a pelvic kidney added in. Dr. Wang took extra precaution and time to be as minimally invasive as possible. He was patient, cautious and honest throughout. I don't like pain medication and he's not heavy handed with it so that worked perfectly for what I did and didn't really need. I'm just about 8 weeks out and happy to say I'm beyond healed- I feel better than I ever have. I'm so grateful to Dr. Wang, the staff at Dr. Wang's office (notably Sara), and the amazing team at Newport Hoag for exceeding my expectations from care to recovery and follow up. read more

Dr. Wang performed by colostomy re-section surgery. The original colostomy, done by another surgeon, was a severe emergency with huge perforations of the bowel, peritonitis and other problems, so it was an ugly re-construction situation to deal with later when Dr. Wang took on the re-section. He spent a lot of time trying to improve my internal situation and remove excessive amounts of scarring. He did a great job and I was on my way home in 5 days. Just had my 2 month post op visit and all is well. Dr. Wang was recommended to me by multiple other physicians and surgeons. You can trust that you are in good hands with Dr. Wang. read more

Dr. Wang is an extremely talented surgeon. He works long hours and truly cares about his patients. He operated on me a week ago. The procedure wasn't easy but I had complete confidence in his experience, along with his ability. I'm 8 days post-op; he told me from the first day of surgery, that I should push myself to get up and walk and to not sit in bed. I'm certain his advice has helped me heal quickly. I like this doctor so much that I wouldn't lower his ranking; but if his staff was reviewed, they would find that some staff members are capable of ruining his stellar reputation. read more

I was admitted to Hoag Irvine in May 2024. I was under the care of Dr. Peter Wang. After a week of antibiotics, it was decided that I needed to have colon resection surgery. I absolutely love Dr. Wang. He is straight forward, takes his time explaining things to you in a way that you will understand, and he doesn't sugar coat things. I felt very safe, calm and comfortable being in his care. He made sure I knew exactly what was going to happen during surgery, and exactly what was expected of me after surgery. I felt that he was very caring, but also very firm with what I needed to do to heal so that I would not develop clots and die. The level of care that I received from every single person during my two week stay was top notch and I couldn't have asked for anything better. Dr. Wang is a fantastic surgeon and I am so happy to have had him as my attending surgeon. I am a lucky lady! I would highly recommend him to anyone. I am beyond grateful. read more

Dr Wang is an excellent surgeon and a caring individual . He promptly responded to any of mine or my husband's calls , whether it be late at night or early in the morning . I highly recommend him. He took great care of me in and out of the hospital ! read more

I met Dr. Wang roughly 6 months ago. I had two hernias one the size of a softball, the other size of a golf ball, neither really bothered me. At 65 I thought I should take care of these before they got any worse or caused me any issues. Dr. Wang was very clear and what to expect. Today I had my three month check up during the surgery. He found two others so there was a total of four hernias he was able to repair with mesh. I'm completely healed no discomfort and release to do my normal activities which include a beach cruiser ride daily of about 16 to 20 miles, weight training and stretching daily. Looking forward to playing golf and Pilates. read more

I am 6 months post op nissen fundoplication surgery with Dr. Wang and could not be happier. He was up front about the recovery and process. I feel great, and very grateful for his excellent surgical skill! read more

I met Dr. Wang at Hoag Emergency Department when I went in for emergency intestinal surgery. I was a very complicated case, and he handled my emergency surgery confidently, professionally and with much compassion. His expertise was spot on during recovery and he knows exactly what he?s doing for best possible outcomes. My recovery was miraculous, and I am indebted to him for making best case scenario results from worst case scenario problems. My recovery has been quite painless compared to other surgeries I've had which has been an incredible bonus on top of everything else. I highly recommend Dr. Peter Wang. I've already told all my friends to seek him out if they need a surgeon. read more

Dr. Wang took out my gallbladder in November 2022 and, without hesitation, I would highly recommend him. The ER staff at Newport Beach Hoag Hospital had very good feedback about Dr. Wang prior to my surgery, and....they were right. Turns out, I was blessed with an unusually large gallbladder with an unusually large gallstone (almost 6 cm). I am glad Dr. Wang, with his many years of experience as a surgeon, ended up doing my surgery. pre-op interactions were very good. He answered all my questions. He followed up post op and answered some more questions and explained what I should expect from the coming days/weeks. I just wish I had my gallbladder taken out sooner (by Dr. Wang) and avoid myself a whole lot of unnecessary pain. Many thanks to Dr Wang and the Hoag ER and Hospital staff. read more

DO NOT USE THIS PETER WANG!! Insensitive, egotistical, non-caring. Any time someone has to tell how "great" he is, that is a huge warning sign to investigate thoroughly. He performed an unnecessary hiatal hernia surgery to enhance his resume. Before realizing that the hiatal hernia surgery was not necessary, he was to perform an umbilical hernia surgery in the near future. The umbilical surgery was to be done at the same time that a hysterectomy was to be performed. But Wang was a no-show and I never saw or spoke to him ever again. He never made contact with me nor had the courtesy to explain his actions or communicate in any form. So I went to a different doctor for my umbilical hernia. After the X-ray for the umbilical hernia, he saw the results of the hiatal surgery. He commented that the hole in the diaphragm which the esophagus passes through on the way to the stomach was not that large and he decided not to comment further. Needless to say our next appointment will be with a malpractice attorney to see if we have a case. A hiatal hernia surgery is when the stomach is tied into a knot so the stomach will not protrude past the diaphragm. The results of that protrusion is heart burn, reflux, and burning sensation in the esophagus. There are less drastic measurers than a hiatal hernia surgery. This surgery was an excellent candidate for the ring insertion. Which is a ring that is placed around the esophagus just above the stomach and just below the diaphragm. This prevents the stomach from protruding through the hole in the diaphragm. The result of the hiatal hernia surgery is you CAN NOT vomit. You CAN NOT belch. You won't have heart burn or reflux, but what a price to pay. All your gas has only one exit and that is through the intestines and out your rear! Having constant UNCONTROLABLE gas is humiliating, Especially when the initial problem could have been solved with the "ring" type operation. The ring type surgery still allows one to vomit, belch and to be able to pass gas more naturally. I had the hysterectomy, but still have the cancer and not being able to vomit is extremely painful. DO NOT USE PETER WANG!! read more

I was admitted to the hospital with a small bowel obstruction, one we thought/hoped wouldn't need an operation. After a week of the waiting game. it was time to operate and who better than Dr. Wang?! From the beginning, he was always very honest with me that surgery was a possibility. I have a history of GI issues/surgeries so it was a very last resort, but was needed. There were never any surprises throughout my stay, he was always honest...which at times hit me like a ton of bricks, but its better to have all the facts. He's knowledgable & I wouldn't have wanted anyone else to operate on me. After some time you will get to see the fun side to him & he will always ask if you have any questions for him before he leaves the room! Dr. Wang works with an incredible nurse team at 4East Hoag Newport! You all made the 2.5 week stay bearable. Thank You. read more

I had a very positive experience with Dr. Wang. I needed a hernia surgery and it was scheduled for a Monday morning. Dr. Wang called me Friday afternoon and told me that he had a family emergency. He gave me the option of postponing the surgery to another date, or he would come in on Saturday and take care of me. He explained to me that I would be on a standby list, because there are no scheduled surgeries on Sat. I told him I was more than willing to come in on Saturday. Saturday morning I was called by Hoag staff to come in asap. 2 hours later I was in surgery with Dr. Wang. The surgery was outstanding and so was recovery. I would highly recommend Dr. Wang. read more

Excellent surgeon, thorough in approach Dr. Wang performed surgery due to acute appendicitis with periappendiceal abscess. He took his time to treat me with antibiotics and a cleanse before recommending surgery. By all accounts, it turned out to be a complex surgery which he accomplished successfully as I am now recovering. My condition had a "high morbidity rate", today I am very grateful I was in the hands of Dr. Wang and the whole team at Hoag Newport Beach. read more

Dr.Wang performed an open appendectomy and partial colon removal due to rupturing of my appendix at Hoag Hospital in May 2023. He is very straightforward and highly knowledgeable. My surgery was not laparoscopic due to other preexisting conditions. Dr. Wang is a very busy surgeon, but his talent is amazing. I am great full he was my surgeon. I have seen him once post op and have one more appointment. Thank you Dr.Wang and Hoag hospital team. read more

Dr Peter Wang was the surgeon on call at Hoag Medical Center in Newport Beach when I had an emergency cholecystectomy on the first night of 2025. I had no history of gallbladder problems until the day before, when I suddenly had a bought of pain as I was exercising to begin my New Year's exercise resolutions. As I was doing abdominal exercises I suddenly experienced the worst pain of my life. My neighbors drove me to the ER. I'll be forever grateful to the physicians and nurses on call that night. They called Dr Wang to perform emergency surgery. At that point I had already developed sepsis. Dr Wang and his associate operated to remove my infected gallbladder. Since then he has continued to check on me weekly and to bring in consultants to follow me with antibiotics. Over the next 6 days in the hospital I was told by many of the medical staff that I was fortunate to have had Dr Wang on emergency duty that night. read more

I met Dr. Wang at Hoag back in October with my first battle with Diverticulitis and I had a rupture and huge infection. Dr Wang helped me through my journey and up until surgery back in May. Dr Wang performed a Colon Resection and he was so meticulous and a perfectionist! He not only performed my 6 hour plus surgery with such patience and professionalism to do his best so that I didn't need to have a colostomy bag. Which the surgery was a complete success! Now I'm fully recovered in less than 4 months. I trust and thank Dr. Wang 100% for what he did for me! read more

I have had two abdominal surgeries by Dr. Wang. He took the time to meticulously perform them by using robotic techniques that required more time and skill than normal to achieve the very best outcomes. One of the surgeries was an unexpected emergency that Dr. Wang performed late at night after having had a full surgery schedule that day. He has a great sense of humor that puts a patient at ease. I would definitely recommend Dr. Peter Wang! read more

gracia por salvarme la vida. en el año 2023 me operó dos veces y en estos momentos tengo una vida excelente, el dr wang se preocupó por mi recuperacion y me ayudó con tantas dudas que tenía sobre mis cirugías . atentamente Maria ximena mendieta read more

The total score that can be received is a Five within this review, I will score it by category. (1) For his years of experience, which are many years, I will give him that. (1)For his dexterity, and precision. (1) For always trying his best to his ability, within his specialty. (0) For his horrible staff, I agree 100% with all the other reviews, that say his staff is inefficient, because of lack of proper management. Lack of customer service, lack of medical knowledge and lack of professional etiquette. (0) 不诚实 / deception. Total =3 star read more

Dr. Peter C Wang is a great surgeon. He recently performed a robotic surgery on me at Hoag Hospital, and I could not be happier with how smooth the process went.

As a nurse Dr wang is an excellent surgeon. He does a great job with patients and has amazing outcomes. He's a funny guy and great at his job. Don't believe the 1 star haters that evaluate everything 1 star in their history read more

This Dr. saved my life plain and simple! I have cancer and it metastasized in my small intestine. After going to ER and being admitted with belly pain that never stopped and nausea and getting sick that would not quit and scans and consults later Dr. Wang would be taking out part of my small intestine and putting in an ileostomy bag. Well as a patient when you hear that you freak out, which i did. He assured me that it in my case it could be reversible when i/my oncologist are ready, so after 2 weeks in hospital i was home with a bag and back in chemo a couple weeks later. His office staff is really nice and caring and good communication. His bedside manners are awesome i think, he is funny, and he jokes around but when it's time to talk about you and your procedures he is very very straight forward. He takes time with you, i never felt rushed when at an appointment or when he came to see me at hospital bed, my wife thinks he is funny and an awesome surgeon as well. Well after 8 long months of having my bag i got it reversed last week ! So far healing is going good...slow moving cause of my cancer and chemo but i have had an X-ray and a ct scan and it shows everything is nice and in tact with no leaks ! My family and i are very blessed that Dr. Peter Wang was assigned to my case !! I cannot wait to see him in a couple weeks and show him how good i am doing !! read more

I was fortunate enough to have Dr. Wang as the surgeon for an emergency appendectomy, then two more surgeries. He is a very skilled surgeon on the highest level, and I love his office staff. They've all been very considerate, compassionate and kind. I especially like the operator ... She's great! Dr. Wang communicated with my family members and me in a very straight forward manner, which we all appreciate. We love his sense of humor! He is a very compassionate man who has a kind heart and soul. read more

I recently required surgery and Dr. Wang was recommended by my physician. Dr. Wang is a very experienced and professional surgeon. He explained the procedure where I was able to understand the process and his follow-up care was excellent. The surgery was successful and was minimally invasive. I highly recommend Dr. Wang and will use him in the future if I require an additional procedure. read more

I highly recommend Dr. Wang for the most important reason--surgically he is the MASTER! I have worked in medicine for 35 years in different capacities: I have seen surgeons in the operating room, cared for their patients post-surgery and have audited their records for quality standards, so I consider myself a justified critic to post a review. This doctor is beyond competent, he is a brilliant surgeon and has had more experience than most other surgeons in not only our area, but the nation. He operates at the finest facilities with the best equipment available in medicine today. These are the attributes that matter most when you are a patient about to be operated on. I read reviews patients write about their doctors and usually they are addressing how nice the person was, how long they waited in the lobby, if there was a billing issue. Yes, these are important if you are planning to spend a lot of time connected to the office, but really, those are not why we go to a doctor, particularly, a specialist. We go to receive specific care. Nine months ago, I found myself ill with a colon condition that was not going to get better. My gastroenterologist referred me to Dr. Wang to have a left hemisphere colectomy. This is not a diagnosis/prognosis to be flippant about your surgeon of choice. I knew his reputation at Hoag Hospital to be the one the nurses and other physicians would personally choose for themselves and family members, so I knew this was where I belonged. Dr. Wang was prudent in obtaining all necessary diagnostic testing prior to scheduling my surgery so as to be best prepared for the best outcome. Although I was a difficult case, I was able to be a candidate for robotic assisted laparoscopic approach to my surgery, only because of Dr. Wang's specific skill set. Most other surgeons would have opened me up either mid-line or full zipper incision. This meant I only have 5 tiny incision scars, only a 3 day hospital stay, minimal blood loss, no leaks, no ileostomy bag, no complications, and I returned to work part-time after only 2 weeks. To address the niceties, I love Dr. Wang and his staff. I feel very cared for. You have to realize, this is a busy surgical office. The doctor schedules cases in advance, and other patient's cases worsen and have to be moved up. The doctor also is on-call at the hospital and emergent cases happen that are not scheduled. So, the nature of a surgical practice is that rescheduling and wait times do happen. Don't be a hater, it is what it is. But, rest assured that when it's your time to be the focus patient, you have the BEST surgeon at your bed side. read more

Dr. Wang is an incredibly talented surgeon! I speak from experience as someone that frequently works with him and many other surgeons in the operating room. I recently needed to have my gallbladder removed. I specifically requested to have him as my surgeon and was in the best hands.

Dr. Wang saved my life with his decision for an emergency colonoscopy. My family and I will be eternally grateful to him for this. He was clear and concise with his explanation of the situation and although I've never had this procedure done I feel like he did a great job. He pushed me every day in the hospital to do what was needed for a quick recovery. Because of this I went home with the same mentality and continue to push forward. Thank Dr. Wang! read more
