Patient Comments

    It was very pleasant and thorough

  • May 05, 2019

    Very thoughtful and took the time to answer all questions. Well prepared...had looked through and understood medical records prior to visit and had a plan in mind.

    Pleasant, thorough, answers all my questions, provides me with clear instructions on my self care.

    This was my 1st contact with this doctor who was very pleasant and helpful.

  • May 02, 2019

    He listened, he was thorough, thoughtful and I left with a plan.

  • Apr 29, 2019

    Dr. Vanek is a very good doctor. I'm very confident in him. He lacks a little in social skills, seems a little nervous with patients.

  • Apr 28, 2019

    My experience with Dr. Vanek has always been a professional and in a caring way, we get a little good relationship as far as that goes - like I said, he's very professional and he gets me in and he gets me out, and we get everything taken care of with the appointment. So I really appreciate having him - that's for sure.

  • Apr 26, 2019

    Professional, personable, clear, humane, construcctive

  • Apr 25, 2019

    Very please with the service from Dr. Vanek.Thank you.

  • Apr 25, 2019

    This provider is probably very knowledgeable of his medical speciality but has limited patient interpersonal skills which I find very tragic and self limiting. All of my experiences with other OHSU providers have been exceptional. I found myself having to turn to another provider at OHSU for help with the side effects of my thyroid disorder because he ignored my request for help. Luckily I was able to get excellent treatment for the side effects of my hyperthyroid condition. I have never before given an OHSU provider a negative review and I write this with the hope that help will be offered to this provider.

  • Apr 25, 2019

    He is very kind and listens to concerns and has a positive attitude about helping to correct medical problems. He also appears very knowledgeable in the field of osteoporosis.

  • Apr 18, 2019

    Very good, very good, very good.

  • Apr 11, 2019

    Dr Vanek is always very forthcoming and helpful. He is excellent in keeping track of my condition as as Type 2 Diabetic and quick to respond with information or action whenever I contact him, e.g. to order tests before scheduled visits.

  • Apr 11, 2019

    The provider was exceptionally knowledgeable and prompt, communication was stellar. Was extremely impressed.

  • Apr 05, 2019

    He was nice, but not very present or informed. I have an autoimmune condition where almost all literature says not to eat gluten. I told him I’ve seen improvement since not eating gluten and he kept encouraging me to eat it or ignore that. He also didn’t take the time to talk to me about my main concerns. He just focused on one set of labs. I was asking about overall issues like preventative heart health associated with my condition. Overall, I waited 4 months to be seen and he was one of the least informed doctors I’ve seen.

  • Mar 24, 2019

    She is excellent. I can't even describe him when he he gets right to the point and to find out the results the next day for me. He's a 10 10 10 10/10. Okay.

  • Mar 21, 2019

    He's usually on time he gets right to the point. He reviews your records before you get there. He knows what you're going to say when you're there and he's funny at times. What key do I punch? I'm done.

  • Mar 14, 2019

    Dr. Vanek was extremely helpful in explaining the reason for my referral, including details re: the results of my recent DEXA bone scan. In addition, he showed me a helpful web site re: bone density, and printed out info. from the site. As it turned out, my bone density is fine, however I wouldn't have known that without his expertise.

  • Mar 14, 2019

    Dr. Vanek is an excellent provider. He is short on words but is kind and caring. He knows his stuff and I thank him for helping me restore my health 2 years ago. He had a no-show yesterday and saw me early rather than make me wait for another hour for my appointment. He pays attention to me and asks questions that are pertinent. I am so glad he helps me with my health issues.
