Dr. Visser is a superb surgeon, excellent doctor, and an overall nice person. I would highly recommend him to everyone.
Thank you!
Dr. Visser is everything I would want in a surgeon who deals with life or death surgical issues. Dr. Visser is direct, patient, informative, and has given me the data and benefit of his experience necessary for me to make an informed decision as to my treatment for my condition.. He answered my questions directly, and did not approach me telling me what he thought he wanted me to hear; he was forthright in explaining the risk/benefit analysis of my situation. Dr. Visser personifies why I only have sought care from a top tier academic medical center for my previous four cancers, as well as for other serious medical conditions. Dr. Visser's experience, training, and competence is why I sought his opinion as to the prognosis and best approach to my medical condition. In the final analysis I trust him.
I think he is very straightforward and to the point. I like him.
Dr. Visser's advice to me and approach to my situation was of tremendous value to me, and I appreciated his directness in his advice to me regarding my particular illness as I went in to my appointment with him having total confidence that I was going to have a consultation with a surgeon recognized as being at the top echelon of his field. I have been around for a long time, and have had a dozen surgeries in my life, five for cancer, and I always have appreciated a surgeon who would give me the data that I need to make, when taken together with his/her advice, an informed decision as to how I should proceed, especially when we are dealing with cancer. Dr. Visser took th time not only to explain to me the direction I should consider taking, and the risks involved, but also the analysis based on his experience considering my particular situation that formed the basis of his opinion. Dr. Visser personifies why I seek care at an academic medical center like Stanford when issues are complicated, as opposed to local medical facilities. Having sat on this information for a few days, I am comfortable in proceeding with Dr. Visser's suggestions as to how I might wish to proceed in the immediate future, as opposed to rushing into a complicated life changing surgery before doing so is, in the final analysis, necessary to prolong my life. I appreciate all that.
I believe he is an excellent physician, who cares about his patients and I consider him to be excellent in his field. Have shared it with others about his excellence in his field and his demeanor, is great with his patients.
Dr. Visser is a great physician. He is very knowledgeable and answered all my questions.
Dr. Visser has been professional, informative, supportive and kind. I appreciate how he explained my diagnosis, type of surgery (no other treatment options), what to expect during surgery, recovery and future treatment. He did a fantastic job removing the Gastrointestinal Stromal Tumors and Lymph nodes in and around my stomach. If my cancer returns, I feel confident Dr. Visser will remove it successfully.
Dr Visser is a wonderful caring doctor, always very professional and he's very knowledgeable. I have complete confidence in him and he always demostrates that he cares about the patient and he's very tenative to the patient.
Vesser saved my life

Dr. Visser provided excellent care and responded directly to my questions. He quickly pulled up anything from my records that applied to our conversation. The session was divided into a prep portion with a resident and a few minutes later the session with Dr. Visser. I am completely comfortable with this approach. His whole surgical team was very professional and actually fun to work with through the entire process. The result was all I could have hoped for!
Dr. Visser is an exceptional physician, thorough, excellent communicator.
Dr. VIisser and his team were stellar. We are choosing to travel 300 miles to habe him perform my surgery because he offered state of the art surgery that is not available in my area. His team took time to thoroughly understand my needs and carefully explain my surgery and care.explain

Dr. Visser was very helpful and professional throughout my whole ordeal I would highly recommend him to anybody who needs his help I Believe if it wasn’t for Dr. Visser I would not be here today
Professional, competent, empathic, humble. Last August 2021, I lost control of my vehicle and blacked out. I was faced with a massive, life threatening, unexplained intra-abdominal bleeding and underwent emergency surgery. As a physician I consulted from my Nevada hospital bed with many institutions, friends, and colleagues to help solve this mystery across states and continents. The hospital transfer to Stanford was difficult in the midst of a covid surge, hospital beds available were scarce. Several institutions and specialty services rejected requests for advice and transfer. Dr. Brendan Visser of the surgical oncology service took on my case. Ultimately there is still no exact certainty about what happened and this episode will remain a medical mystery. Thankfully I recovered and am in excellent health. I will never forget and remain extremely grateful for the courtesy and care extended to me by Dr. Brendan Visser and his team at Stanford.
The visit was detailed to the point where I understand what I wanted to know.
Very informative visit and gave me great confidence that I fully understand what will happen next. The risks are worth the potential personal gain. I am ready to go.
Very thoughtful Dr
He convinced me I will live under his care.
Everything was explained to me to my satisfaction. Very professional team.
I appreciated that Dr. Visser was candid, upfront and to the point concerning my medical situation.
Excellent caring physician
Provide reassurance and responded well to all my questions and concerns!
I am extremely pleased with Dr Visser and his care team. He and everyone on the team are caring, responsive to questions, easily accessible and put me at ease when I felt apprehensive about the condition and my care.

Very dedicated to my situation.
Excellent, outstanding doctor

Dr. Visser is exceptional, very thorough, very caring and the best.
First comes into room and states rather abruptly I don't like your pulmonary function.
Utmost trust in Dr. Visser. Couldn't have a BETTER doctor.
Dr Visser saver my life!
When I asked about my CT scan, I was told not to worry about it. He said the other doctors do not know how to read them. He asked me if I had any questions. I asked him about one of the things that was on the CT scan and again he told me that the person that wrote about what they saw on the scan did not know how to read it. He never explained why. I left wondering why three other doctors, that do not know each other came up with the same conclusion. I tried to tell him that something else is going on but he said that everything is good with me and not to worry. That is hard to do when I am feeling sick.
Drs. were knowledgeable and explained things well. The only negative aspect was that Dr. Visser was continually paged and had to take a phone call during my appointment.
Dr. Visser explains everything and cares very much.
Dr. Visser was EXCELLENT in every way.
Dr. Visser is clearly an expert in his field, and he was honest and straightforward with me about not knowing what kind of mass I had, despite that being difficult news. He & his staff recognized that they could help me sooner rather than later & worked to make that happen.
I am in good hands. Am very happy I came to Stanford.
They rush in late & rush out immediately... having someone else come in... very unorganized or lack of communication.
Very good.
Quality of care at Stanford has been outstanding.
Dr. Visser is a caring, excellent physician who is an asset to your hospital. He is very knowledgeable & is very professional in dealing with his patients. I am so blessed to have him as my surgeon/oncologist.

Was final follow-up visit. Dr. Visser has been a "life saver." A pleasure to have been his patient.
Excellent physicians & NP. Very detailed and compassionate and concerned about getting me immediate care. Also called me at home to keep me updated.
Dr. Visser and his PA (Kristen?) were personable and professional to a fault. I couldn't have asked for a better care team.
I am very confident in Dr. Visser and his team of experts.
Dr. Visser & Dr. Basina are the best in there fields worth my having to drive 50 miles to see them.
Dr. Visser and Kristen Wheeler were exceptionally helpful and articulate in explaining my symptoms and procedure needed.
Excellent experience at all my appointments and treatment.
Dr. Visser and his team are excellent! They are very knowledgeable and explain everything to me in a way that I can understand fully.
I can always depend on Dr Visser and his team are there for me with the answers and corrective action
Dr. Visser, Kristan Wheeler, Taylor Foyel, Monica Dua and all of Dr. Visser staff were very kind and friendly! Best office experience I ever had.
Dr, Visser did not share any information I did not know. Did not offer any recommendation other than surgery as expected. More in depth analysis of my unique condition would have been helpful. Statistics in probability of progression on my pancreatic NET was missing.
I think that Stanford Health Care is the best we have in California all excellent.
great. great. great wonderful doctor
Dr. Visser was AMAZING!!
Everyone was nice and caring and made me comfortable and understand about my physical condition. Dr. Visser is good and knowledgeable person. I would highly recommend to others.
I feel blessed that Dr. Visser took me in as a patient. he has been working to correct damage implemented by a previous hospital. I am not sure where my health would have ended up without his expertise - Very grateful.
Dr. Visser was amazing. He answered all our questions & concerns... He was very kind. His PA that saw us the first day was amazing helped with drsg. D & skin.
I am still confused about the information from the consultation, and I can't find a way to get questions answered. I think Dr. Visser is an excellent surgeon, but I will probably either cancel or delay the surgery. Also, if they won't respond to phone calls now, and I had a problem after surgery, would they respond them? Maybe not.
Dr Visser had review my case before entering the exam room. He put me at ease and instilled confidence that he is competent and knowledgeable surgeon.
Very good.

Could not have been a better experience totally being treated by Dr. Visser and his PAs Kristen and Tanya.
I am cancer free and alive today because of Dr. Visser. the only doctor after seeing so many who diagnosed my cancer and had the capability of performing my surgery
There was some use of medical jargon for which I had to stop the provider and ask for a clarification.
Dr. Visser great clinician!

Surgeon was highly recommended to me by oncologist at PAMF. Nothing in subsequent appointments w/this doctor altered my impression of this surgeon.
I have total confidence in Dr. Visser. If I were asked where I wanted to go if I had to go the hospital; it would be Stanford.
My high marks are made without reservation. I cannot imagine better care from all levels. Thank you.
Always was put a ease. All test results were carefully explained. I always felt very good after each visit.
the information was both refreshing and a bit daunting as I have a rare problem and the surgeon recommended a second surgery to deal with the problem.
PA went over CT scans with us & explained very clearly.
Provider was just wonderful
Actual time spent with Dr. Visser helpful! Good explanations & answered all questions satisfactorily.
Thank you again!
no bad experience
I will gladly recommend both Dr. Visser and Dr. Heestand and their PA to Friends and Family
World's best doctor thank God for him.
Doctor was a bit distant, hurried, not engaged with me as an individual (but, not unusual for a surgeon).
Dr. Visser explained very clearly & answered all questions we had.
Always the best of care.
Dr Visser is a very nice man who can come down to your level and explain to you what he thinks. He is very good at being honest and providing you with any choice there may be. I liked his style very much. He knows people come to see him and they are nervous I believe Dr Visser realizes this and shows care and kindness yet he does give you the feeling he is very confidant but in a good way NOT an arrogant way.
Dr. Visser impresses me with his knowledge and expertise in his field. He makes me feel very comfortable and at easy when talking to him about my condition. He tends to explain things in easy to underst terms without feeling you are being talked down to.
Dr. Visser & his staff are awesome!
I consider Dr. Visser to be highly capable and kind. He has my utmost respect.

I feel that I am in very competent hands and could not ask for more.
Dr. Visser highly experienced doctor. Very courteous, politeness, friendliness. I never see doctor like dr. Visser in my life. God will give long life.
Dr. Visser was the first professional after seeing many doctors that came in and told me exactly what my health issue was and how to proceed. He explained every detail of what needed to be done leading up to my surgery in preparation to the details of the surgery. Dr. Visser takes his time and explains everything in a way that a person who is not a doctor can understand. he cares about his patients and his work.
I get respect and kindness there.
My husband and I felt like members of the treatment team and that we participated in determining the treatment plan. I wasn't told, this is what we are going to do.
