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. Janice is one of the best Doctors I have ever engaged with. His bed side manners are superb. Hes kind and smart and educational. Hes patient and respectful and listens carefully and with compassion. He made me feel safe and secure. Hes been very honest and open with me and has quick responses to my messages aka emails. Hes caring and I trust him and am so grateful hes my Doctor.

First visit: Inspires confidence; comprehensive asessments; interview and physical. Expresses interest and concern. Communicates concisely and clearly, presents the plan and welcomes and responds to questions. Does not waste his or my time.

Dr. Janis is everything you could ask for in a Doctor. I am not easily impressed nor do I trust easily. He is really focused and seems like a very bright person. He listens to you, he talks to you, he tries to understand your situation, and he cares how your feel. He came highly recommended by another cardiologist that I had worked with before.The cardiologist that spoke highly of him is a wonderful doctor and a caring person himself so that recommendation carried a lot of weight. See this MD!
