I can describe myself as semi-pro: I don't do poker for a living, but I have a nice profit from the game. I started playing poker back in 2010 and finished every year so far with profit ( total profit of 20k$).
However, I never was brave ( or stupid) enough to quit my job ( which I enjoy a lot) and try to do poker for a living. However, I do know a lot of people from the industry some of them literally millionaires from the game. Some of them are at the moment in Vegas playing the World Series of Poker.
Actually, I run a poker coaching websites where we have coaches teaching other player how to improve at the game. All of the coaches are professionals and earn their living with the game. They all have 5 and 6 figure profits and support their families through the game. If you are eager to learn more about them or ask them anything here is a list with all the coaches I currently have on my website:
