About Barbara

I became a realtor in 1987. I specialize in residential resale in the northern Middlesex County, Somerset County and Hunterdon County areas. Since 1987 I have received numerous sales awards including the current 2017 Circle of Excellence award. Having graduated from the prestigious Real Estate Institute I have obtained my GRI designation, only obtainable after additional Real Estate study and experience in all fields of Real Estate transactions. I have also obtained my brokers license. If you need help or advice for any of your real estate needs feel free to contact me.
