Sorry to say but 'big deal'.

Ditto.

I have been doing something (in another field) since the mid 90's. I would say most people would consider me an expert. I get referrals for what I do from 'top' people investors in tech. I also went to what most would consider 'a top college'. I would never want to be positioned as being right or expert because of the amount of time I spent doing something or the college that I went to, or who trusts me, but actual things that I have done that point to my expertise (not a halo of some type).
