Dr. Peter Chi Wang, MD

Dr. Peter C. Wang patiently listened to my questions, giving me complete and full attention, and answering every question in a clear and comprehensible manner regarding colectomy surgery. He did not rush me through my appointment. He showed genuine concern and interest for my well-being. After initial consultations, he performed my very successful surgery, for which I am grateful for his skill and knowledge and exceptional care. Dr. Wang is truly outstanding. Because he is so excellent, there may be a wait before an appointment, but he takes time and genuine interest in EVERY patient. If there is a wait time, he is worth it....no matter how long.

Following a Liver Transplant in 2020 and a Kidney Transplant in 2021, I began having issues, with little warning, with small bowel obstructions in May 2026. As I understand it, the culprits were Scar Tissue Adhesion and Incisional Hernias, both of which were quickly and competently addressed laparoscopically by Dr. Peter C. Wang. Given his extremely full schedule, I was very fortunate he made himself available to repair my very serious health issues.

Dr Wang is by far the best, most knowledgeable doctor I have ever had. He saved my life! I would highly recommend him to everyone, he has great bedside manner & a great sense of humor!!

Dr Wang saved my life via emergency intestinal surgery in 2024 (incisional). Reversed my ostomy in 2025 (incisional). Installed a hernia mesh in 2026 (laparoscopic). 3 surgeries, 3 successes. He tells it like it is … it’s up to you to do your part (lose weight, change diet, exercise). His office staff is amazing as well. It’s a busy office so waiting is normal. But to get the best surgeon, sometimes you have to wait. Thanks for saving me, Dr Wang!

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.

Dr. Wang is an exceptional surgeon and, in my opinion, among the very best in California. He takes the time to thoroughly explain the procedure, including potential risks and complications, and thoughtfully includes family members in these discussions. From the moment you meet him, his professionalism and confidence inspire trust and reassurance. He clearly outlines the next steps both before and after surgery, ensuring everyone feels informed and prepared. Dr. Wang also goes above and beyond by personally involving family members in post-surgical care, patiently demonstrating proper wound care and making the experience feel genuinely personal. I have nothing but the highest praise for Dr. Wang and am deeply grateful for the care he provided. Bravo Zulu!!!

Dr. Peter L. Wang, MD – Outstanding Surgeon & Compassionate Care I cannot recommend Dr. Wang highly enough! His surgical skill is truly exceptional, but what makes him stand out is his genuine care and personal touch. From the very beginning, he made me feel comfortable with his warm demeanor and even a great sense of humor. When the nurses were busy, Dr. Wang personally removed my stitches—something you rarely see from a surgeon. He also gave me excellent advice on diet and nutrition to support my recovery, showing he cares about the whole patient, not just the procedure. I’m deeply grateful for the incredible attention I received from Dr. Wang and Hoag Medical Group. If you’re looking for a surgeon who combines world-class expertise with compassion and authentic connection, Dr. Wang is the one you want.

I was sent to Dr Peter Wang after my urologist determined I had a fistula ( a hole in my bladder ) . My bladder was attached to my semi colon & created a pathway between the both . This was not a good situation & he suggested i see Dr. Wang . I did call right away but he was so backed up that he could not see me for another 6 weeks. I was experiencing a UTI for months now because of this & was in pain . My persistent calls to the office for any appointment cancelations paid off & i got in . After he evaluated me , he determined i was in dire need of surgery ASOP. He explained to me he was backed up for months , but he told his front office that I had to be priority since the condition of my deteriorating health . He got me in within 2 weeks , performed a normally 2 hour surgery ,but mine took 6 hours since it was so bad , and followed by a normal 3 day hospital stay that turned into 11 days for me to make sure I was good before I got out . I am forever grateful to Dr peter Wang .

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.

If I could add more stars I would. My encounter with Dr. Wang started when my father had to be rushed to the Hospital (Hoag Hospital) he was immediately evaluated and admitted into the hospital. He was too weak to have any surgery done at first, after a few weeks and under the guidance of Dr. Wang, my dad had a very delicate surgery. Dr. Wang provided me with updates through out the 4-5 hour long procedure. Afterwards, Dr. Wang provided me with what we can expect the coming days and weeks. An additional amount of weeks before my dad was discharged. This all happened in October 2024. Since that point Dr. Wang made sure my dads wound was treated properly and educated me on how to care for it when home health wasn’t available. This is the 3rd procedure my dad had that was emergent and the first time with Dr. Wang. I can say with confidence that had Dr. Wang been his surgeon the first time my dad had the surgery- my father would not have needed any additional surgeries. A true and honest… professional. I’m glad my father received the care he needed! Thank you Dr. Wang for saving my fathers life. Thank you for the continue care and support. I hope there are more like you.
