I highly recommend him. His staff, depending who you get answering the phone will or can be helpful. Often you're sent to a VM or not answering at all. That happened to me several times. Again I liked Klein a lot.

Absolutely unacceptable billing practices…read more I was overcharged for a preventive screening -- something that is 100% covered by insurance. Not "maybe covered." Not "partially covered." Fully covered. And instead of automatically correcting the overpayment once insurance processed the claim, this office just... keeps the money unless you call and demand it back. Let that sink in. They will not issue refunds automatically. The patient has to catch the mistake and call. How many patients never even realize they were overcharged? How many people assume the office knows what it's doing and trust the bill? This office handles insurance claims every single day. They know how preventive services are billed. They know preventive screenings are covered at 100%. Pretending confusion or acting like this is some unpredictable insurance mystery is insulting. This isn't a rare coding anomaly -- it's routine, standard billing. Patients shouldn't have to audit their own medical bills to make sure a provider isn't sitting on their money. If you overcharge, you fix it. Automatically. Period. If you go here, scrutinize every single bill and compare it to your EOB. Apparently, that's the only way to make sure you're not quietly overpaying.

He printed me over 50 pages of scientific literature and said it should go away. Luckily English is my first language and I have a science background (I don't mention the second part ever). Well guess what, I went to another G.I. got some blood tests, CT scan, and it was something bigger. If you want someone who will miss something, go to this doc. If you want someone who will listen to you, advocate for you, go to any other doctor. I only took this appointment because it was the first one available, I'd recommend anyone to wait for another doctor, even if it's another one in the same clinic. This was the first doctor that I actually left in tears. Do not waste your time.
