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.

This dr does not even deserve 1 star!! My Mom's liver enzymes were never checked by this man!! Mom went religiously to have her blood work done. She had type 2 diabetes that turned to liver cancer. He never cared about her. I was on the phone going through mountains trying to get his office to refer us to a specialist! Good luck if this is your dr.

This is not about my experience woth dr warren but the multiple times he has disrespected my grandfather and ignored any signs or symptoms my grandpa has told him, dr warren siple says nothing is wrong. In fact he told my grandfather, a veteran, when he came in for an injury on his arm that "medicare doesnt pay him enough for bandaids" and handed him a napkin. This guy should never gone into this practice.

Mis-diagnosed kidney stones as a UTI, ended up in ER twice as a result. Refused to treat me and told me I needed to see an Obgyn. Dead wrong,if it were not for an ER doctor recognizing the symptoms and ordering a CT scan who knows what would have happened. Extremely RUDE secretary, have to beg to see the doctor and the doctor is only available 12 hours a week. M,T,Th,F from 9-12. So don't get sick after lunchtime or on a Wednesday!!!
