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. O’Brien and Dr. Rogan are the best cardiologists by far from others. Well mannered, trustworthy and very transparent and pure reflection of good character and More than knowledgeable of what needs to be done. I consider them the wisest cardiologists you’ll ever meet.

Dr. O'Brien is very caring, light hearted, and funny. Most important is that he is very thorough in his examination. His staff was equally pleasant.

None better than O'Brien. Caring for my husband since a HA in 09', and our prev. Dr. in Vienna suggested he wait at PW hosp. till morn. Hosp. ER Doc called FFX Heart and O'Brien said send him. Copter ride and stint surgery an hour later saved his life. I failed a pre surgery exam and am being treated by him for AFIB. I am in great shape, have lost lbs. with RNY weight loss surgery and have the skill of his care keeping the scheduled surgery with his treatment. Healthy as a horse now. The BEST!!

I meet Dr. O'Brien in the Emergency Room at INOVA Fairfax on 12/13/1999. I was in coronary arrest, Thanks to him I am here enjoying life with family and friends. I am now 73, feel great and can do just about anything that I want. As long as Dr O'Brien is still practicing he will be my DR.
