New Practice, how to get folks in the door

So I’ve been working like a dog 6 months to get this new practice open. I finally get the doors open and the phones just aren’t ringing, the only patients I’m seeing are the ones coming from my old practice, and I’ve come to realize I have no idea how to market. I’m in network with all the big insurances. I’ve got a decent website with online scheduling and I’m trying to do the social media stuff. I come from a super shitty corporate job where the phone literally rings nonstop with people trying to get in, so I guess I thought taking insurance was all it took. What do I need to do?
