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 Johnson is very thorough and listens!

Consult visit
Office staff very friendly and kind. Dr. Johnson spent time reviewing my history and validating my experience and previous care from other health care providers. He included me in making a plan for any future care, and I was reassured that I could always contact him for any concerns. I appreciate his expertise, he was easy to talk to, his explanations very clear and I would recommend him as a specialty physician to anyone. I thank him for his care and encouragement.

Not responsive to providing enough medical informa
While his medical degree wld indicate he knows so much valuable helpful medical information, Dr.Jhnsn refused for almost two weeks to Provide This Former pt.with prurient info.after repeated requests. I left. I need information given and specifics and facts. He 'sugar coats'. Not appropriate. He judges. Not appropriate. Never at The Mayo.Clinic in six months did i experience the Irreverence that Dr.Jhnsn pushed. He did not help me so i left.

Dr Johnson and his team is a wonderful caring group of people. The special attention I have seen them give to my husband and others in the cancer center is awesome. I tip my hat to them.

This visit was a pre-infusion visit, going over my labs and updating any symptoms. Dr Johnson is compassionate and professional in his demeanor. He is open to questions and provides clear, unambiguous answers.
