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.

Was in fact mis-diagnosed by Dr. Rosenthal for having MS. She treated me for MS for over 6 years and never shared spinal tap results with me. My current neurologist re-examined my case along with new tests and reviewing past results and confirms that I have NEVER had MS!!

She was a total Godsend. I can not say enough good things about this wonderful doctor. She was so personable. She spent over an hour with me each time. She was the friendliest and coolest doctor. She was very thorough. She is an excellent listener and a great talker. I highly recommend Dr. Ro

First of all you have at least an hour wait no matter what time your appointment is? Then she says she sending me for an outpatient procedure, after they put a pick line in my neck, then I get to spend xmas and New Years in the hospital when I have my cousins from England visiting? Then it takes over 2 months to get a sleep study done then I go for my appointment and one of her staff shows me a bill for 300.00 that I did not know a thing about, makes me wait in the waiting rm for over two hours
