"As real estate professionals, we sometimes we forget that buying and selling a home can be overwhelming and draining. I want the process to be fun and exciting for all of my buyers and sellers." The most enjoyable part of the business for Maggie is seeing the smiles on her clients faces when they get to the closing table, about to start a new chapter in their lives. Joining a team lead by two powerhouse veterans, Bob Arnold and Erna Russert, Maggie is thrilled to bring her experience, team player mindset, and positive attitude to the BAIR Group.
