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 Roost was very thorough and took time to explain each step of the procedure. He is patient and kind

Dr Roost is very knowledgeable and offered some great remedies as I am a menopausal woman. Again, I have never been to a male OB/GYN as I was not comfortable at all. He was very kind and made the room feel very comfortable. I will definitely definitely recommend him to every person I know.

Dr. Roost and the office were very busy, but he seemed as though he had all the time in the world to discuss my care and even casually chat. I appreciate his holistic approach to medicine, making his care collaborative and covering all of my needs/wants.

Dr. Roost is the best! He always takes time to talk with me and see how things are going at home. I appreciate that my appointments aren't just a quick chat, diagnoses or test and then leave. It's nice that he takes time to get to know me and remembers things about me and my family. He always listens to any concerns that I have and talks through options with me.
