Just wanted to issue a review/warning about this place!
I attended a Wedding at the Pine Knob Mansion in Clarkston this past Saturday, and while it is a beautiful venue, the staff was horrible. The banquet manager was rude, problematic, and unkind. It seemed to me that the banquet manager was trying to ruin the wedding. Conflict was also caused with the Photographer and DJ by the banquet hall manager. The staff was unprofessional in every way possible, and that was apparent to the bride, groom, and all guests. I have never felt so unwelcome at a wedding before, and I feel horrible for the bride and groom for having to deal with such difficult people on their day.
I am planning a wedding as well, and I will never use or recommend The Pine Knob Mansion.
