“Thompson Street came to us and we noticed a little something unique about them that we liked … they had done their homework before they met us … they were obviously very prepared … actually, I was quite impressed by it … being a businessman who’s never been through this experience before, I had a lot to learn but I’m very glad I got to learn it with Thompson Street being involved.”
