Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

I started with heart palpitations on a Friday 7 years ago. They were very persistent and this was my first episode so I became very anxious. I called Virginia Cardiologists and Dr. Onufer was on call. He put me totally at ease and arranged his schedule to see me first thing Monday morning. I cannot say enough about Dr. Onufer. He is so knowledgeable, caring, explains in layman terms and is just a GREAT guy . I felt like I was the only patient he had to see that morning. Solved my PVC's with medication. You all are very fortunate to have Dr. Onufer in Arlington Heights although I really wish he was still in Richmond , VA. Gail Duncan in Richmond, VA - October 9, 2019

My mom had a heart arrhythmia for 2 years. We went through diagnostics exams and hospitalizations at different hospitals back and forth for 6 months. While at Northwest community emergency, Dr. Onufer was our life saver doing the ablation immediately and curing this long-drawn heart problem.

Dr.Onufer is the most excellent physician that I have ever encountered . I have had issues with heart arrythymias - he has performed two procedures on me - a heart ablation & another procedure to implant a pacemaker . He was very prompt & thorough during office visits about why I would need these procedures and how the procedures were performed - he is extremely easy to talk too - also a great listener ! I always felt very well cared for - He is the bEST - a great guy !

Dr. Onufer performed a hybrid maze procedure on me along with Dr. Bundy (cardiovascular surgeon). A follow- up procedure was required 1 year later which was performed by Dr. Onufer alone. Both operations had excellent outcomes with no post-operative complications. After the second procedure I am now A-fib free for the first time in 30 years. Dr. Onufer is extremely skilled and competent and posseses a very good interpatient relationship, clearly explaning the operation and the risks vs. benefits
