My t works in a practice with 2 partners. They have a receptionist. My pdoc works in a clinic setting. I've seen solo practitioners before. I like the small office with partners. It's never crowded in the waiting room, but there's not the risk of T taking advantage because there are checks in place. I had a T who billed my insurance for appointments I didn't attend and I've never known if it was because he was forgetful or unethical.
