About Margaret

A local perspective. A personal commitment.

My philosophyWork Hard and Do the Right Thing.

Born and raised in Seaford, New York, I moved to Reading, Massachusetts when my husband accepted a job in the area. I expected that we would spend a couple of years in Boston and then return to our home town. What I did not expect is that I would fall in love with the charm and possibilities that we discovered in the Greater Boston region. Purchasing our home in Reading and raising our three children here has proven to be one of the best decisions I have ever made.

I decided to make a career change and became a realtor in 2012. I knew instantly helping others achieve their dreams was my passion and what I was meant to do. My business philosophy is simple, 'Work Hard and Do the Right Thing' This philosophy has proven to be effective as I continue to be a multi-million dollar sales agent, year after year.

I utilize cutting edge technology and a never ending dedication to providing the highest level of customer satisfaction to help you through one of your most significant financial decisions.
