Is he the right doctor for us?

So after a year and a half of trying, my husband and I went to a fertility doctor yesterday. He is supposed to be one of the best in the state and has the best

numbers in the state, so we waited a while to see him and were excited (and nervous) for the appointment.

We get called into his office and the first thing he does is pull off his mask and say is "you don't have to wear your mask if you don't want to, my covid test came back negative". Right away that made me a little uneasy about him. Doesn't sound like a doctor that takes my health seriously. After that he goes on to talk about his businesses and how his genetic testing business is traded on the stock market, etc etc. Basically bragging about himself. He tries to over some blood test numbers with us, but his manner of talking made him so hard to understand. Boastful, unwilling to explain things or speak of things in a linear fashion. It was also, really hard to talk to him or ask any questions. I felt like I was being swindled by a used car salesman.

I got some additional tests done at his office, but I'm not sure of I should keep him as my doctor. I was practically in tears leaving his office, but if he has the best results of any doctor in the state, does is make sense to stay with him?

IVF

(if we go that route) is super expensive and I want to maximize my chances of getting pregnant the first time, but I can't stand that man! I dislike him as a human being. What do I do???
