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. Wenzel, Endo
On this regular follow-up visit, I saw Dr. Wenzel after his nurse administered the A12 test. I was impressed with Dr. Wenzel’s healthcare decision making, excellent listening skills and clarity of expression in explaining and providing information. I also enjoy his ascerbic wit. I am very satisfied in my choice of endocrinologist in this small town setting.

I’m 72 yrs old and have been to many many dr in my time. Dr. Wendel was the rudest, most callous Dr I’ve ever been to. He didn’t care to hear my complaints and was actually yawning several times like I was boring him. At the end of the visit he says, ‘Come back if you want to.’ I’ve been to Drs that didn’t have bedside manners but he was just down right rude. I made a comment of how I was small in my younger days and he said, ‘well, your not small now!’ I will not be going back to him.

Do not recommend
2 visits with the Dr. 1 visit did not like the approach of what he ask. 2nd visit. I asked him what would be the next step. Answer "Hopefully I will be gone by them and it will be someone else problem." Not going back. Should have not gone back the second time.

Dr Wenzel is a wonderful Doctor. Saved my life.
He knew I was in they Hospital, he pulled the charts, videos. He found a 95,% blockage in my kidney! Sent me to the ER for surgery. He is a very Concerned Doctor! He calls me personally with the lab test he runs. He coordinates my care by calling the heart Doctor to compare notes. I trust him above anyother of my Doctors.

Dr. Wenzel has been difficult to deal with for the years I have been a patient. Due to the challenge/bother of finding a new doctor, I have put up with it. If you have an option, please look elsewhere for quality care.

Dr. Wenzel is the BEST!
Our daughter is 31 years old, a little person, and medically fragile. She is life time steroid dependent. Dr. Wenzel has worked with me to keep her steroids, Vitamin D and Iron to levels that are right for her. He is methodical, matter of fact, and steady in his approach to her care. I am so blessed to have him guiding her care through the endocrinology discipline.

Excellent Physician!!!
Dr Wenzel is very caring and thorough. I love him to pieces!!! He takes very good care of my mother who is extremely difficult!! Their banter is very humorous. My mother always goes home happy and the most important thing is her A1 score is improving!!!! No one has ever been able been able to bring her score down. All the people that can't appreciate Dr Wenzel don't know him. We have been going to him for several years. What he has endured with my stubborn mother is amazing. He sits there and listens, tells her straight what she needs to do even if she doesn't like to hear it. No sugar coating it. And my mother has dropped 2 A1 points so far when I never thought it would ever change. I have faith that she will get even better with Dr Wenzel on her watch!!! Now I want to become his patient because I have started to have some problems. He is great!!!

Not on your team
I had a full throidectomy and went to Dr. Wenzel to help monitor my T3/T4 levels and make sure my sythroid medication is keeping my levels within the normal range. He sent me to do a routine blood check, but missed some key labs that check my T3, T4 levels. After having my synthroid meds change, it was odd that additional tests weren't part of the labs so he could see if my levels were still on point. When I asked him to add the labs, he said no. When I asked for an explanation, he said, no reason for them. This doctor is not on your team so if you are looking for someone who will explain why something is or isn't part of his diagnosis, keep moving.

Both my father and I are patients of Dr. Wenzel. He treats us both for diabetes and he also treats me for a thyroid condition. He doesn't beat around the bush and he gets the job done. We trust him and know that he provides us with excellent medical care. It did take me a while to warm up to him when he was first taking care of my father, but I quickly grew to appreciate his no nonsense approach and I know that he is diligent in helping us manage our health conditions. I would definitely recommend Dr. Wenzel.
