Mary Gillach is a true professional, with a strong sense integrity, always an immediate response with all questions pertaining to the selling of our residence. The Gillach staff followed through and represented my interest, from the sale to the closing, Gillach and her staff are the epitome of excellence.

M.K. – Bought a home in Auburndale, MA in 2017.

I cannot say enough good things about Mary’s group. We chose to work with them to buy our new home in Newton because Mary had sold my parents’ home, then helped my mother buy her new home and they were so thorough, attentive, and professional. Laura was the person we had most contact with – she came with us to look at houses and acted as a friend providing good advice and insights. When we finally found the right house, Mary arranged a private viewing of the property hours after the open house and then that night helped us figure out comps and come up with an offer. She was very methodical in her approach and understood that we were doing this for the first time and made us feel very comfortable. We can’t thank Mary, Laura and the rest of the group enough for everything they did for us – we recommend their group to anybody without hesitation.

Aron J. – Bought a home in 2017 in Brookline, MA.

We began our search for a new home in 2015, and after a pretty disappointing experience with an agent who seemed more interested in getting the sale than helping us find the right place, we re-started the search with Mary’s team in 2016. The contrast was evident from the beginning. Mary and her team were extremely professional, and clearly interested in helping us find the best place for our family. We focused our search in Brookline, and Mary and her team helped us navigate the extremely competitive market (for several months) before landing our new condo in a great location, and quickly selling our place in the South End (for quite a bit over asking). We’ve already passed Mary’s information along to several friends and colleagues in the market for a new home, and will be giving her a call again if/when we make our next move.
