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.

If you have a tough 24/7 case of Afib, Dr. Sirak's 5 Box Maze procedure should be your top choice. It's the most thorough minimally invasive maze surgery available. Dr. Sirak developed it and has perfected it. I looked at many options to cure my long standing, persistent Afib, and this was the surgery I chose. I made the trip to Lima, Ohio just to put my heart and health in Dr. Sirak's hands. Was it worth it? I'm now Afib free, sinus rhythm and no medicines! Highly recommend Dr John Sirak for fixing your Afib.

Bad— my dad was pushed into open heart surgery at a hospital dr sirak isn’t even listed as a surgeon at! He told my Dad he would feel like a new man… and My dad now can’t even stand and has had nothing but complications since then! Would NOT recommend him doing surgery.

I had the Five Box Thorascopic Maze Procedure done by Dr Sirak in February 2015 and it has completely stopped my AFib. My recovery time was very short and I have only positive things to say about the operation. Dr Sirak is an exceptional physician and I highly recommend the Five Box Procedure.
