    I had surgery and I think it well. I don't remember much

  • Jan 11, 2019

    Was friendly and gave me the information I came to find out. Was also pleased that he will follow up as needed and my patient advocate said he thought the visit went well and was high quality service.

  • Jan 05, 2019

    I was referred to your clinic. My file was sent before my appointment. We drove 250 miles the night before (overnight stay). When the Dr walked in the room, he glances at the screen and backs away kind of laughing. He is not the type of Dr for my issue. Really??? He was kind enough to do as much legwork as he figured the correct Dr would want. He also had the staff set all the appointments for the tests and visit with the correct Dr.

  • Jan 03, 2019

    Dr. Geltzeiler is extremely knowledgeable about his work and he has extreme excellent bedside manner. She was very comfortable. My daughter was very comfortable while he did her surgery as well as office visits. He took a lot of time to answer any and all my questions and make sure that I was comfortable with the work that was doing and anything that he does. So I would definitely recommend him to anyone that I know.

This follow-up appointment allowed me to get all of my questions answered and provide me with a path for the future of my healing and treatment.

  • Dec 24, 2018

    I really appreciate the care that dr. Geltzeiler provided for me at OHSU on December 21st. He went above and beyond protocol to ensure that I was well cared for. Because of my hemophilia.

  • Nov 11, 2018

    I like Dr. Geltzeiler a lot. He was thoughtful, he was, I felt he took time to talk to me. I have only seen him twice. So because of that, I know I would recommend him, but you know, I haven't been under his care for very long time. So it's a positive report. I think he's a fine person, and I think he's explained things very well to me.
