Sherman Oaks, CA |
He is all about money. He now charges $25.00 to call a pharmacy and if you see him every month, he charges an extra $55.00. This is out of pocket. It doesn't matter so much about how fine he is because he is all about money. He kept my $1000.00 that I paid for shots and also kept what insurance paid. I checked on my own. I was then told not to get anymore shots!

Ratiner is a meny grubbing doctor and he is known by my other doctor's with that reputation. One doctor told me that the office doesn't like to send records to other offices. He now charges $25.00 for each phone call to pharmacies. He tacks on $55.00 extra if you see him monthly. How professional is that? He kept the money paid to him by my insurance and what I paid him. He told me there was no coverage for my shot, and I checked, and there was. That was $1500.00.
It's nice to have a physician who actually takes the time to discuss what is happening and involve you in this solution. Your in good hands and I highly recommend Dr. Ratiner! Mary V.

I’m 53 & have been diagnosed with acute autoimmune diseases of the colon, joints, skin and brain. Having seen 100+ doctors in my pursuit of relief; it’s safe to say that I am an expert! Dr. Ratner’s thorough, methodical and insightful approach to patient is beyond compare. My first appointment was 2 years ago and my overall health has dramatically improved, I’m 80% - 90% better! Dr. Boris Ratner is the Real Deal and the best I have ever seen!

This DR I WAS with no heart. He told me that I have RA in the most nasty way. He said ' I AM A BUSY MAN". I had to go to a specialist who told me that I do not have it. I was treated in unprofessional way. I would tell you that he is unpleasant. Yes we are in pain, but I would seek another DR.
