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.

Terrible doctor
RUN FROM THIS PRACTICE FAST. Dr.Allen Immediately doubts my diagnosis, wasnt listening to my concerns, didnt order any tests or lab work. Didnt try any medications. Then unprofessionally and privately harasses me by calling my personal phone talking about a review i left on google! This guy needs his license taken away.

Feel safe
Dr. Allen has been my cardiologist for years. He was my mother's dr first. He cares, he leaves no stone unturned . He gets answers. I feel safe with this Dr because he gets the answers. He found that I have pulmonary Hypertension when my pulmonary Dr didn't. Not 9 ly did he find it, he treats me for it.

Staff has always been kind and pleasant and very helpful. They run late sometimes but it’s a big hospital. Dr Allan and his assistant spend time listening to me. I have Chronic Lymphocytic Leukemia and I trust him.
