Taking lessons with David Gary at the Wetlands. What to expect?

So little backstory. I've played golf off and on for about 3-4 years. Probably average of once a month, although I've been playing a lot more lately.

I had never really played golf in my life when I started. I just kind of stumbled upon the game and loved it. Bought a used set of clubs and went on playing from there. When I started I really had nobody to teach me anything, so I was just kind of learning as I went. Had an old man that used to play at the same time as me at a club I used to be a member at. He attempted to give me pointers, but they weren't really helpful. I've watched a lot of videos on YouTube to try to figure out things I may be doing wrong, but it hasn't helped much.

I've shot in the 90's twice in my life. Other than that I'm usually around 110. I know it sucks, but I enjoy playing. If I'm going to keep playing I figured I should try to pick up some good habits and make playing more enjoyable. Golf is literally the only sport I've ever played where if I didn't just naturally improve as I played more. That's very frustrating, but also challenging which keeps me going back.

So I broke down after my last round and got the lessons. Anybody was in a somewhat similar situation as me and took lessons with David Gary? What should I expect? How much should I hope to improve? I got the package of 4 lessons from him, by the way.
