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 not reading reports correctly
He was comparing two ultrasounds, which showed two completely different things and measurements, and DID NOT notice it, instead come up with a ver scary assumption which was based on purely nothing but not being able to take the time to read two different reports correctly. My primary doctor and two independent gynobs reviewed it again, and were just shaking their heads. One thing is, to be proactive and to exclude any major threat, another thing is to be arrogant and unattentive and not to properly read reports. Will report further.

Words can't describe what a wonderful and caring doctor he is. He delivered all three of my kids, all four of my sisters boys and my little brother. My family has trusted him for years. During a difficult delivery you can always trust that he will be right by your side. Love, Love, Love him. Top recommended to my family and friends!
