i would very much like to maintain contact with my professors, im glad to hear that it's a real possibility.

As someone who has always walked a bit outside of the norm, and felt this way towards my own professors in college, I would tell you that the relationship post college greatly varies on the connection made during classes and the professional connection of your career.

For example - I had an IT professor that I really connected with. I was almost always ahead of my class in studies, worked on projects outside of class that were related to IT, and semi-frequently sought guidance from this professor on my college and career future. I would consider our friendship akin to professional colleagues as we are both in the same field (though he’s teaching and I’m actually in the field working) and I still occasionally contact him to share resources, things he can teach his current students about, and am part of his committees for future course creation.

It really depends, but we don’t “hang out”
Or spend time together outside of this professional relationship. It’s a way for him to remain a mentor to me and I try to reciprocate that courtesy by sharing what I learn and how it applies to what was taught when I can (or whatever other resource I can offer as an exchange)
