Denise Georgeff

Office Manager

My name is Denise Georgeff. I live in Melbourne, Fl. and I started working for PSAG, Inc. in 2014. I am the Office Manager and I oversee all incoming submissions prior and post the expertizing process. I also handle all correspondence with former and new clients. Over the years, working with Randy, I have learned so much about philately and the history of the postage stamp, which, I have to say, is my favorite part of my job next to talking with our wonderful clientele.
