I have great confidence in him and his diagnoses and treatment

I just think he needs to stop looking at his watch, trying to stay within the short little window and provide the time necessary to really listen about someone’s health concerns. If he’s ordering bloodwork anyway, why would he not just have me provide the urine for a urinalysis when I tell him I think I have a UTI? His response to my request was that I do not have a UTI because I would’ve brought it up right away. I believe that he did not want to pause one second longer to discuss it just have me prove a urine sample. He literally dismissed my concerns about the blood work being done on a full stomach and also told me I don’t think that’s necessary regarding the urine test. I told him my urine was a very dark color and he said drink more water. I drink around 90 oz per day. I should not have had to go to Walgreens to pay money for a urine test kit after I just went to the doctor..very disappointed with this visit and now I want to go to a different doctor. It’s great to be efficient with your time, but it should not come at the expense of your patient.

Dr. Andersen is a wonderful doctor, he and his nurse Nancey were very up to date with all off my medical history, Dr. Andersen gave me great advice on how to be healthier going forward at my age. I am so very fortunate, and appreciative of Dr. Andersen's care and concern for me. Thank you

The best Doctor I have ever had

It was fine except I had to return for the other blood test because it was not done only one blood test for thyroid was done, not the one for blood sugar. I did go back and just to lab to get the other done so this was resolved. I was relieved to have my results ultimately for both of the lab work done.
