About me
I am a surgeon who specializes in treating:
Colon, rectal and anal cancer are potentially curable for many, if not most, people. I provide custom care for each patient. Whether I’m seeing you for your first visit or a second opinion, I will learn what is important to you and make sure you understand your cancer and all treatment options.
For other conditions, I treat each patient individually, working with you to find the best treatment for your symptoms. We can often do this with office treatments and without surgery.
I joined OHSU in 2005. I am part of the OHSU Digestive Health Center and the OHSU Knight Cancer Institute.
My research interests include:
- Treatment of rectal cancer without surgery
- Hereditary colorectal cancer syndromes such as Lynch syndrome and familial adenomatous polyposis (FAP)
I started the state’s first colorectal cancer registry and have worked with other researchers at OHSU to continue our leadership in colorectal cancer research.
I am committed to providing top-quality individual care to each patient. Because of this, I’ve been recognized as one of “Portland’s Top Doctors" and one of "America’s Top Surgeons.”

I continue to be impressed and pleased with Dr Herzig. He lightens the mood around the procedure but asks lots of questions and is concerned not only for my health and comfort but also my insurance coverage, which is appreciated.
My 3rd colonoscopy in the last 2 years with this group. Always great!
I hope Dr. Herzig will be available for all my procedures.
Dr. Herzig is is fantastic, very knowledgeable and compassionate.
Super helpful, informative and fast! The procedure did not take very long at all.
Dr is knowledgeable, explains things well
I felt a concern, and answered my questions.
Dr. Herzig is the best doctor I've ever had anywhere!! 10 out of 10actually he's a step above all the rest.
I have been seeing Dr. Herzig for several months. I trust his expertise.
Highly professional, informative
Dr. Herzig is the best of the best. He had done my first colonoscopy 10 years ago and I specifically asked to have him do my second one for continuity of care reasons. I trust his expertise, and he is also kind and personable.
First class
So caring and knowledgeable and sensitive to the nature of the problem.
He was efficient and reassuring.
Well, the main thing they serve very well, very respectful, very friendly
Docs nurses and anesthesiologist all very approachable and friendly.
Felt heard, seen and interacted well
I felt safe and well cared for. Well informed. Staff were all courteous. I was covered and warm until I fell asleep.
Informative - asked for input and was able to answer my questions
Dr. Herzig is amazing!
Trusted care. Will be returning for suggested future exams.
Dr. Herzig is the best!
It was great
Everyone always answers my questions and is very helpful
Dr Herzig was wonderful. He cares. His words after the procedure were especially helpful.
The anesthesiologist and CRNA were exceptional. I felt comfortable and safe, I knew I was in good hands. Dr. Herzig was friendly, making sure I had any questions answered. I liked his quiet confidence.
Dr. Herzig was the most professional doctor I've interacted with regarding these issues. He not only made me feel comfortable, but made sure my concerns as a queer person were addressed with zero stress or discrimination (this has been something I've had issues with in the past.). I'd hands down recommend Dr. Herzig to anyone who's facing similar issues and intend to do so.
Efficient & nice.
Sadly there is no way to ask questions to the doctor who performed my colonoscopy via MyChart. I have to ask a nurse to ask the doctor then wait for the nurse to receive an answer and then reply to me. If further explanation is needed this convoluted process seem ridiculous. Asking questions while recovering from anesthesia and remember the answers provided is a waste of everybody's time. At tis point I doubt If I would recognize the doctor If he was standing next to me In the grocery store
Very positive
