Dr. Sun and his team are absolutely amazing! Months ago I was researching what neurosurgeon to go with for our daughter who has lipomyelomeningocele. I saw Dr. Sun’s accolades and decided he was the doctor for us. Even though we had a children’s hospital much closer to us than UCSF. I remember looking at these reviews in tears mentioning to my husband that I couldn’t wait to write this five star review like so many others before us. Here we are a month post op from our daughters spinal cord detethering surgery and I couldn’t have picked a better surgeon. Dr. Sun is precise and took his time. Her surgery was a success and her incision is healing nicely as well. From our first appointment to our latest post op appointment Dr. Sun and his team have answered all of our questions. They were informative and upfront with the possibility of any unknowns that could happen during surgery. You always want the best for your kids especially in situations like this. Choosing him as our doctor is the best decision we could’ve done for our daughter’s well-being. If you are looking for the best neurosurgeon this side of California look no further he is it. We will forever be grateful to him, his team, and the nurses that cared for our baby girl during her week stay at the hospital. Dr. Sun and his team are absolutely amazing!

I can’t say enough good things about our experience at CHO. Dr Sun’s team was caring, professional, & supportive. Our 6 yr old daughter required brain surgery for a benign tumor & cysts that were discovered after a routine ophthalmology appointment at UCSF. We met with Dr Sun the day after her MRI, & he very calmly went over the plan for surgery with us. He took his time to explain everything, even basic concepts - we had been thrown into the deep end with her diagnosis, & he was there to help us figure out what to do. The craniotomy took many hours & went extremely well - better than we even expected. It’s terrifying to entrust someone with your child’s life, but when we came back to her recovery room & heard her chatting away with her nurses, we realized we were in the absolute best hands & that Dr Sun had saved our girl. After surgery, she stayed in the PICU for another 2 weeks because Dr Sun really wanted to avoid placing a shunt. He & his team worked diligently to get her brain fluid draining correctly on its own - it was extra effort from them that was ultimately successful & meant she was able to go home without a shunt! I’m so grateful to the entire team for the care our family received. I would recommend Dr Sun & CHO to anyone needing pediatric care. I can’t say enough good things about our experience at CHO.

My 8 year old daughter was diagnosed with AVM. Her brain was swelling and had a huge blood clot. He had to do emergency surgery. They told us she may never talk again . 4 hrs after waking up she was singing. They also told us that she would be in the hospital three weeks to three months. They released her just 6 days after surgery. She is right back to her normal self. I thank God and Dr. Sun My 8 year old daughter was diagnosed with AVM.

Dr Sun and his team are so wonderful. I remember when I was researching treatment options for our baby and I was able to meet with Dr Sun for a second opinion. He spent so much time answering all of my questions in detail. I had a great experience with his team and my baby had an excellent surgery outcome. We are now two years post op and have a happy and healthy two year old. Thank you Dr Sun! Dr Sun and his team are so wonderful.

Saved my life when i was a kid

He saved my daughters life. He is extremely professional, confident and his team is phenomenal.

Our daughter was born with metopic craniosynostosis, which is early fusion of the suture that connects the frontal bone of the skull. If unrepaired, it restricts normal skull and brain growth, which can lead to increased intracranial pressure, abnormal head shape, and developmental delays. Upon learning of our daughter´s diagnosis at 1 month of age, we began our search to find a neurosurgeon. The first neurosurgeon we saw recommended open cranial vault remodeling (CVR), which involves removing, remodeling, and then replacing the malformed bone. This sounded terrifying, like Frankenstein surgery to us! However, we were willing to do whatever was best for our daughter. I began extensive research online to learn more about this surgery. I learned that there was another option available: minimally invasive endoscopic repair followed by helmet therapy. Only a handful of surgeons are trained to do this, including Dr. Sun, one of the top neurosurgeons in the country. We thanked our lucky stars that we were able to get a consult with him. Dr. Sun is exceptionally skilled and experienced in endoscopic craniosynostosis repair. Although he also performs CVR, he assured us that endoscopic surgery with helmet therapy would provide the best long-term results. We were grateful to have had an early diagnosis, as there is a short window period when endoscopic repair can be done (ideally at 3 months, when the bone is still soft). Although this was a less invasive procedure, we were still overwhelmed at the thought of our baby going through surgery. Dr. Sun and his staff were incredibly patient, informative, and reassuring during the whole process. The surgery went smoothly and we were able to go home from the hospital after 3 days. Following surgery, we started helmet therapy to help her skull continue to round out in a natural, gradual manner. Helmet therapy lasted a total of 6 months, involving regular check ups and helmet adjustments. Dr. Sun and his staff were always so happy to see our daughter and shared our excitement about her excellent progress. It has now been one year since surgery. We could not be more pleased with the results of the endoscopic repair. Before surgery, our daughter´s forehead was pinched and triangular-shaped, and her eyes were close-set. Now you would never guess that our daughter ever had metopic craniosynostosis. She is a happy, active toddler that is meeting all of her developmental milestones. We are beyond grateful to Dr. Sun and his team for the incredible life-long impact that they have made in our lives.

Dr. Sun saved my son, Joey’s, life by believing in me as a mother and going the extra mile and not giving up until we found the problem. We had seen 3 Neurosurgeons before meeting Dr. Sun in 2007 and he is the most upstanding, caring, and dedicated Neurosurgeon we’ve experienced. My son kept having shunt malfunctions, collapsed ventricles, and SYRINGOMYELIAS forming in his spinal cord and cervical spine. We found he developed a CHIARI MALFORMATION and through Dr. Sun and the Radiology staff at Oakland Children’s Hospital, they found by an MRI used in cardio studies a small adhesion wrapped around near my son’s brain stem. This was the first time something was seen doing that particular MRI and by finding this, my son’s case is in medical journals. Through Dr. Sun’s dedication to our children and their health, my son is alive and doing so well right now. I am so grateful to have found him 12 years ago and we know if we ever have any more issues, we’re on our way to Dr. Sun and Oakland Children’s Hospital. We love you Dr. Sun and thank you to all of your staff and Nurses!

If I could give Dr. Sun a better rating than 5 stars I would! He diagnosed our son with Metopic Craniosynostosis at less than a month old. When our son was a little less than 3 months old we traveled to Oakland, CA for Dr.Sun to perform a minimally invasive surgery on our son. The incision was about three inches long and the scar is not even very noticeable unless you’re really trying to look for it. The results have been amazing! We are just so thankful that Dr.Sun did the minimally invasive surgery rather than just doing the more invasive surgery which is one large incision from one ear to the other. We are forever greatful that our son has had such a great, intelligent Doctor throughout this whole journey. As busy as Dr. Sun is we have never felt rushed. He always takes the time to talk about how everything is going, any concerns we may have and is great at explaining things in a way that we really understand.

My baby was diagnosed with tethered cord when he was born. You can imagine the worry and scare we had. After seeing 3 neurosurgeons, we decided that doctor Sun was the one for our son. There was no complication after the surgery. My son is now an active and healthy toddler! I cannot express enough appreciation to Dr. Sun. He saved my son and my family! I truly recommend him! Here is why. 1). Dr. Sun performs a lot of surgeries (it is more important than papers for a surgeon). 2). He is willing to listen, explain and adjust his plan. We met him 3,4 times before the surgery to solve the questions we had and to discuss different diagnosis/plans from other neurosurgeons. We finally reached to a plan that we all thought was best for our son. 3). He is the one who performs surgeries (at least the most scary/fundamental part, e.g, detach the tethered tissue, remove lipoma)! I know there are many neurosurgeons/professors who guide others to do surgeries but he is not one of them. 4). He is extremely careful. He does intraoperative neurophysiological monitoring which is very important to make sure the tissue he is manipulating doesn't affect any fundamental functionalities, e.g, leg movement and sense. 5). He cares. The second night (AM in the morning) my son in NICU, he dropped by to check my son's condition after another long surgery. His eyes were red and he looked tired. At that moment, I knew I made the right choice! Other doctors and nurses told me Dr. Sun always took as much time as he needed for a surgery.

Dr Peter Sun MD is a truly good doctor and the best wold class staff.

Dr. Sun is incredibly personable and wise. We know we are fortunate to have had him as Analicia's surgeon.

Best neurosurgeon period. Direct humility, honesty, and confident in what he does. My son is living tumor free thanks to Sun M.D.

caring, skilled surgeon, helpful and pleasant team.

Dr Sun operated on my son Joel Zuniga in January 2014 when he was 2 years old. Joel was diagnosed with brain cancer known as ATRT and statistics say a 10% chance of survival. I'm happy to say Joel will be 6 in June and I truly believe Dr Sun was the beginning of his healing! Thank you to an awesome neurosurgeon!

best neuro surgeon I ever had

My son, Charles, has Chiari malformation. Dr. Sun and his staff were truly amazing. They did an excellent job providing my child the best care possible. They were immensely helpful and were able to answer any questions I had. The surgery was a complete success and Charles is healing immensely well. He was in so much pain before and now he has no pain! He is beginning to talk, he does not wake up in the middle of the night crying in pain, his eyes no longer cross, and he has not choked a sing time! His school is also seeing a large difference in him. His teacher said during his IEP meeting 'Charles used to be so quiet and always seemed to be uncomfortable, to uncomfortable to be himself, now he does not stop! He has mastered the PEC book and is excelling in every area that was once a concern!' Thank you Dr. Sun and staff! It is wonderful seeing such a large change in what once was a small child in pain and so delayed now catching up so quickly and so happy! My son, Charles, has Chiari malformation.

There was a small miscommunication for the pre-surgery appointment between the third and fifth floors. Because of this, we did not get to do all of the pre-surgery stuff on the day prior to surgery. This caused quite a bit of delay on the day of the surgery. That being said, the surgery was very successful and we have seen tremendous improvements with our daughter, that have exceeded our expectations. The follow-up in-hospital physical therapy required by Dr. Sun was extremely beneficial, and in our opinion was absolutely essential for her success.

Dr. Sun and the staff were fantastic with my daughter. Dr. Sun removed a cyst from my daughter's head/skull. The scar is practically invisible. I am so pleased.

We were told that this Dr had all of my daughter's records, MRI etc and when we saw him we would have plan for treatment. Well he DIDNT have any of her records. He copied the ones *I* brought in with me. He acted like he'd never even heard of her.(Our referring physician said she'd talked to him at length about our daughter) He didn't even examine her to talk to her. She parted her hair and he looked at her scar from last surgery and told us he's Not a pain doctor.

"Loved it" is not the phrase I would chose to describe an experience with a pediatric neurosurgeon, but if you need one, this is the person. One of Dr. Sun's assistants told us "Dr. Sun doesn't just do surgery, he does battle." It is true. On leap day in 2008 he spent 10 hours removing a malignant brain tumor from my 12 year old (at the time). Thanks to his skill and willingness to spend the extra time, he got it all. I will thank God for this man for the rest of my life, for giving my daughter the chance to live her life.
