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.

Unhelpful staff
The staff were rude and unhelpful after attempts to request a copy of my records, which I needed to start treatment.

This doctor is not all there. He misread my charts, lied to me about a surgery he was going to perform and is a poor communicator. Avoid, it may save your life.

Dr. Thampi John performed a Radio Frequency Ablation procedure and caused serious trauma to my right leg (bloodclots) and occluded both my Superior and Inferior Pulmonary veins resulting in three stent placement surgeries. I also have a vena cava filter for the rest of my life due to pulmonary embolisms that he failed to see during an angiogram! I had to medically retire from my job. Patient beware!!!

I saw Dr. John for almost 10 years before I was able to obtain insurance and have an ablation done. I was always very satisfied with him. He is a little hard to understand, but he's a good guy and highly educated. He is NOT after your money, his fees for office appointments at that time were very reasonable. I trusted him, and he delivered. He is a specialist, and they are hard to find in California - only a few can do what he does in this field. You would be well served to go see him.

Dr. John is GREAT! The BEST!! If you have a condition that requires an ablation, do not hesitate to take the referral and allow him to take care of you. Office gets backed up due to number of patients referred to him, but do not let that deter you. Have a seat, read a magazine or book and wait your turn. Dr. John is worth the small investment of your time when it comes to your health.

I wouldn't give this guy a star under any circumstances, h. This doctor almost killed me and he knew it. He insisted on doing a third ablation when he knew that I needed a pacemaker. I ended up with an emergency pacemaker and Dr. John did not come to see me in the hospital the whole time I was there. I wasn't scheduled to be in the hospital but he put me there! This guy should be run out of business and if any of you know what you're doing please, please choose a different doctor. He is a quack
