Connie Fisichello McCollister

Real Estate Agent

Connie is a DC resident and lover of all things HGTV. She loves color, pattern, texture and all the details that give a space personality. She could stroll through farmers markets and go to open houses all weekend long and would brunch every day of the week if she could. House hunting has always been a passion, and to be able to guide others through this process is not only an honor but also makes for an exciting journey. She believes every space has potential to be the perfect home for someone and can’t wait to help you find the perfect one for you!
A 2009 Broadcast Communications graduate from Elon University, Connie spent her first 2.5 years out of school as a part of the licensing creative product development team at Discovery Communications. Her passion for everything home prevailed though, which is how she ended up here today. And as the daughter of restaurant owners, she was born into customer service. It has always been a big part of who she is, so she can promise you the best most personalized service possible.
