BEWARE!!!! They are out of network for United Health care and Aetna (and probably many others), but they will not tell you until AFTER services are rendered. They take the insurance info on the phone when you establish there but never say that they don't take it. So, I am now being billed over $300 for a preventative cleaning that should be included and a zero charge.
When questioned, they say the "assume" people know if they are in network. When the office personnel take the insurance info and book the appointments, we "assume" that means they are!
