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.

Wonderfullly compassionate and knowledgeable. I won’t use any other Doctor. I trust her completely.

Dr, Hayssen is very personable and she asked all the appropriate questions to figure out my issue before her exam. She explained everything she was doing during the exam. Dr. Hayssen explained why I had my problem and recommended medication to help! She was very thorough in all aspects of my care!

Dr. Hayssen is the perfect combination of skill and compassion. At first i was concerned because her ratings weren't as high as i would have liked, but she gave me great confidence in our initial meeting. She thoroughly discussed my condition and then compassionately explained how my health is her health. She performed a great surgery. She stopped by at least once each day while i was in the hospital to check on my recovery and answer any questions. She personally called me and explained the pathology reports when they returned. She referred me to a great oncologist and personally called him to make sure he understood my situation. I HIGHLY recommend Dr. Hayssen.
