Dr. WISSINK is an excellent provider. He always is very caring and listens to any complaints I have, how I'm feeling, and really takes good care of my husband and myself. And I've recommended him to several family members. And in fact, he was recommended to at least six. He has six more patients that I recommended him as their physician. So thank you, Dr. WISSINK.

I think he did very well and he had a partner come in or an intern or something and she did very well too and so did a nurse leading up to his appointment. Thank you. Bye.

I have been seeing Dr. Wissink for several years, one compliant , the assistants that check blood pressure and general information, are so unprofessional, never smile, talk down to me, harsh tone in their voices....this is yearly experience, this does not happen in any other department... most unsettling.

Everyone was polite and efficient at their jobs. Dr. Wissink listened to me carefully, was professional but yet very personable. He was thorough in the review of my issue and discussed options, giving me some choice in how to proceed. I felt very reassured when I left and would see him again (as he is not my PCP.)

I would like to have my doctor do physical exams like used to be done years ago. It appears I have consults, and that's as far as it goes. I assume Medicare has something to do with this, but there is no offer. on the doctor's part to do anything for a physical exam. So I don't know. But I would appreciate that that could still happen.

- 1 out of 5 starsReviewed on 10/5/2025
Substitute provider was fine, but he asked for a blood count and sent me to the Onalaska lab. Two untrained people who I cannot call phlebotomist did not seem to know what they were doing, and I was left with quite a bruise and no results after two people tried and failed. I left. For a while, the Onalaska lab seemed adequate, but my last two sessions with it suggest that training has not been very good at all. I cannot recommend this web to anyone.
