I've been to Dr. Cameron and Dr. Roe. I was seeing Dr. Cameron about the time that he sold the office to Dr. Roe and he made sure to choose someone that practiced similarly to himself. I, too, had been to some that wanted me to come 3 times a week for weeks, but that wasn't the case with Dr. Cameron or Dr. Roe.
As for insurance, I have United Healthcare. They covered a certain number of appts. (I can't remember how many) and it cost me $20 per visit. Now, I'm on maintenance and he's suggested once every two months which I didn't think would bad at all. Insurance doesn't cover maintenance, but it's only $35 for a maintenance visit, which is way better than the pain in the neck I was having.
