Gary Kempker Sr.

GaryIn 1994 Mary Kay's business began to grow and she needed someone to handle the financial side of things while she was on the bench, so Gary decided to join her instead of hiring someone.

His favorite part of it all is working with people to design that one of a kind piece that they have dreamed of and watching their faces light up when he makes their dreams become a reality!
