About Me Personally
My husband and I grew up in Sudbury, spent a few years just up the road in Marlborough and then returned to raise our family here. I have 2 older teenagers who keep me grounded. The Metro West area of Massachusetts has been my playground, both personally and professionally. I know the area like no one else and love to share all my favorite spots and all that the surrounding communities have to offer. Prior to entering real estate, I worked in the fashion industry for over 20 years. I developed a strong sales, marketing and business background. I have passion for "all things real estate" from decor and staging to effective negotiation skills and a unique internet marketing strategy. These collective skills are proven to get your home sold, quickly.
