    Dr. Andersen is a kind, warm, down to earth, doctor with a great sense of humor. But don't be fooled by his easy going fun nature. He is honest, and straightforward and is a well respected leader, and not afraid to work hard and push and get things moving and done for his patients. Excellent doctor and we feel lucky to have him on our side.

    Listened to my history and managed my pain better than my previous surgeons.

  • Dec 21, 2019

    Dr. Peter Anderson is the best there is. I have a super, super rare cancer called ACC, and he knows exactly what to do for it, and how to treat it. It's not curable, but he can cut it out, and do everything that's necessary, and that's available to me for source of comfort and looking forward. I recommend him to anybody who has a rare cancer.

  • Dec 20, 2019

    My main contact at the visit was with his assistant who is excellent and has wonderful bed side manner and very knowledgeable missed and Dr. Anderson is also very personable takes his time. You don't feel rushed you feel like you're going to ask any questions. You will take the time to answer it. So I'm very impressed with with both of them. I know their stuff and I would highly recommend them to anyone. That's it.

    I've received nothing but the best care from OHSU. My recent surgery was a complete success, I'm very thankful for my doctor, and the nursing staff are all awesome. They not only know what they're doing, but they all seem to have a great attitude, which is so encouraging to a broken, recovering patient.

    Dr Anderson and his staff are extremely caring people. Each person explained in terms I could understand their role and what my options might be. Dr Anderson volunteered to consult with Dr Keenan regarding a potential problem with upcoming cervical surgery and the paragangligioma. I feel very comfortable with Dr Anderson's approach to the problem. Bailey is efficient and at the same time calm and pleasant. Dr. Anderson's Resident showed compassion, knowledge and clearly loves her work.

  • Nov 27, 2019

    I was seen earlier than scheduled and treated with courtesy, efficiency, and professionally. I thoroughly appreciate the treatment by OHSU and the staff, and Dr. Peter Andersen proved to be an answer to my concerns. I have nothing but the highest regard for him and the other physicians and nurses involved in my care.

  • Nov 26, 2019

    I had out patient surgery, everyone was very nice, the only thing that was in was since ENT Dept moved, lots of different departments moved around @ OHSU which it took us over an hour to find the right place for check in, other then that everyone was very cheerful & easy to deal with.

  • Nov 20, 2019

    First visit, limited experience. Friendly and timely. Staff went the extra mile to get an immediate appointment for an MRI since I live about 80 miles away.

  • Nov 15, 2019

    Yes. My name is [Name] I met with Dr. Andersen on the 12th extremely personable man I enjoyed our visit and have since spoken with him on the phone and I have every confidence in him. Very scary situation I'm in with this cancer in my mouth. But I feel very confident in him and feel safe. So I don't know what else to say except I'm glad he is my physician. Thank you.

  • Nov 13, 2019

    He is very friendly and very personable and comes in very relaxed. Like you're his only patient, even though we know he's extremely busy. So anyway, appreciate him and all the times that he has actually given calls in the evening.

  • Nov 08, 2019

    Dr. Andersen, is my hero. He knows more about ACC than any doctor anywhere and has been helping me for a long time. He is always there when needed and up front with the information I ask for.

  • Nov 07, 2019

    The surgeon and his co doctor are wonderful. They provide all answers to my questions and both have a great bedside manner. They care and they show it. I feel so comfortable with these two doctors that I will recommend them to anyone who needs the same type of help that I needed and am still receiving.

  • Nov 06, 2019

    Always great visit

  • Nov 06, 2019

    Dr. Anderson and the fellows that work with him are always very warm, extremely knowledgeable and take care to explain what they think is going on and why.

  • Nov 02, 2019

    They're amazing, nice, very thoughtful. They listen and they explain things to me clearly so, thank you.

  • Oct 31, 2019

    I am very pleased with the service provided thus far. Everyone, including the nurse, Resident and Dr. Anderson were very pleasant, professional and answered my questions. This is the second recurrence of my head and neck cancer, so needless to say I am very frightened. Their professionalism did a lot to ease my anxiety.

  • Oct 31, 2019

    Dr. Anderson was very thorough and to the point about the cancer in my neck. Too many factors were unclear and the computer system wasn't cooperating so he didn't have the PET scan to look at. I think that the scan should have been asked for, received and reviewed even before I got to my appointment. All that said Doc did the best he could with the information he had. He did take a couple more biopsy samples from my throat so he could get a more detailed idea of what was going on.

  • Oct 30, 2019

    positive and helpful

  • Oct 30, 2019

    Enjoyed my visit with both the resident and the provider. Friendly, honest, and sincere. Seemed very knowledgeable without being egotistical.

  • Oct 27, 2019

    Very thorough, I feel confident under his care.

  • Oct 26, 2019

    Very good experience at the surgery and the nursing care.

  • Oct 26, 2019

    Excellent service. Thank you.

  • Oct 23, 2019

    Dr. Andersen was wonderful! He took time with me, explained things fully, made it clear what the next steps were. I would have given him an 11, if possible on that scale. OHSU is a big facility -- so although it's very well organized, I prefer a smaller setting. But I would go anywhere to see Dr. Andersen! He's a gem. Thanks!
