Born and raised in the northwest suburbs of Boston, Maureen DeLeo’s familiarity of the region is unparalleled to many in the real estate industry. From growing up in Belmont to raising children in Acton, vacationing in Kennebunk, Maine to currently living in Concord Center, it’s the diversity of the areas she holds dear to her that have aided in the success of her real estate business. Licensed in both Massachusetts and Maine, Maureen is able to use her fondness and first-hand knowledge of those areas to help her clients buy and sell real estate.

Utilizing the experience she gained from a prior career in both high-tech sales and home staging, coupled with her knack for creative marketing, feisty negotiating and an advanced understanding of areas she serves, Maureen is a well respected Realtor within the local real estate community. Given her proactive work ethic and commitment to her clients, she holds a spot amongst the top producers at Keller Williams Realty – Boston Northwest, a brokerage of nearly 200 agents.

Treating every client as a partner, Maureen strives to provide the best experience for them, often being told that she provides a concierge level of service they have never encountered before.

Given these priorities, Maureen seamlessly manages her clients’ transactions, from the first property shown to closing, in a manner that does not go unnoticed.

Understanding that playing the role of both buyers’ agent and selling agent is extremely important, Maureen enjoys serving either side of a transaction as it affords her the ability to better support her clients throughout the process of buying a home, selling a home, or both. Above all, Maureen’s genuine care for her clients and the journey they allow her to be a part of always shines through, giving her an appreciation for a career that creates not just clients, but life long friends.
