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.

Still Doing Great
Dr. O'Brien took care of me after a heart attack 23 years ago. Under his care, I recovered nicely and am still doing well. I'm 79 years old and always get good marks on my heart health. I owe a lot to Dr. O'Brien.

Dr Paul O'Brien is always caring, efficient, effective, and an extraordinary listener/communicator and patient educator. Surrounds himself with caring staff as well. He is the closest cardiologist I found in Northern VA or D.C. that really understood the impact of nutrition on heart health. He was able to put me on a diet (a program that was administered out of his office) that helped me drop 20 pounds; which, in turn, lowered my blood pressure and LDL cholesterol. Years before meeting him, I had stents and a triple bypass surgery due to blocked arteries. He kept me heart healthy for several years, working patiently with all of my drug allergies. He is a meticulous detective and electronically literate as well! I recently moved to PA and hope to find someone with all of his qualifications, experience (to include military!) and caring demeanor. He is a rare gem of a cardiologist!

My husband and I are both patients of Dr. O'Brien. My husband became his patient first, and, through him, I also became a patient. Dr. O'Brien has given us good care, has shown compassion, and is always on top of things. We're forever grateful.
