Thank you for all the responses! You've given me a lot of useful information

The reason I asked was because I was told by a therapist who did not feel qualified to take me on that therapists and psychiatrists take insurance when they are inexperienced because they want to gain some experience and build up their client-base. He said that once they are experts in their field, they stop taking insurance because there are no benefits to taking insurance due to the hassle and poor reimbursement.
