The most important asset of my business is the trust of my clients. I truly enjoy being part of one of the most important transactions in a person’s life. When helping families find their first house or helping others let go of the family homestead my priority is honesty and integrity.

Baldwin has always been my home.  My mother, Rosemary Mensching was an agent with Baldwin Realty and sold us our first house in 1981. I joined Baldwin Realty in 1998. Having earned a master degree from Adelphi University in psychology. My love of people made this a good path for me to take. The fact that 1999 was the beginning of a historic uptick in the real estate market did not hurt to grow my enthusiasm.

I earned by Brokers License and was a top producer at Baldwin Realty. The flexible independence of being a realtor fit my family life. My son Peter graduated Baldwin High School in 2000 and my son John in 2011. Both my son’s and daughter Brianna attended St. Christopher’s School. Brianna graduated Holy Trinity High School in 2008.

In 2013 I became the Broker of Record and Owner of Baldwin Realty purchasing the business from Catherine Gorman who had purchased it from the original owner William Walcott.

After retiring from Municipal Finance my husband Peter Sandroni joined our team. His calming supportive presence and unwavering confidence in me is wonderful.

Over the years our family has enjoyed Baldwin Park, Baldwin Little League, Police Athletic League basketball, soccer and track, Baldwin Bombers Football, Baldwin Eagles Soccer and the Memorial Day Parade.

In 2017 Baldwin Realty moved to the beautiful location at 720 Sunrise Highway, THE KOCH BUILDING. This is the most beautiful building in Baldwin and I hope to extend that beauty throughout the town.
