Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

"Dr." Guenther is responsible for the death of my wife, Barbara. He failed to diagnose her lung cancer. She saw him every 2 weeks for 2 years. She was terribly sick. He couldn't find out why. Finally, one trip to the ER revealed a softball dize lung tumor. Barbara died 2 weeks later. Guenther is personally responsible.

I should have done this a long time ago. Dr. Guenther was my late husband's doctor and later mine. His treatment of my husband was outstanding. He always, absolutely always, responded quickly to crisis's as they came up. This was extremely important when he got sepsis. My husband actually lived through sepsis because of the speed to which Dr. Guenther's care. My husband's treatment plan was brutal, as developed by UW Health and administered locally. Dr. Guenther's care was critical.

Even with the best of intentions he pushed long term high dosage use of unneeded medication. Despite his dire warnings about stopping, I am better off without the toxic medication. Years have passed since and I wish I had stopped long before I realized the damage it was doing. I regret going to Dr Guenther, he really scared me into poisoning myself.
