Shabnam Mashmasarmi, COO

Shabnam born and raised in Brockton, dedicates her life to helping families build wealth by representing sellers and buyers, who are first time homebuyers, investors, wholesalers and/or developers.  As part of her passion to helping families build generational wealth, she educates her clients and communities on asset protection and estate planning techniques. Shabnam believes property ownership is not just about acquiring it, but protecting and sustaining it for years to come. 


To ensure Black communities have access and opportunities to real estate development and ownership, and to ensure Black women and those disproportionately impacted by the existing barriers be part of the conversations, Shabnam partnered with Chanda Smart and established OnyxGroup Development and Realty.

In the years prior to establishing OnyxGroup, Shabnam partnered with Suffolk University Center for Real Estate as Program Consultant. Shabnam also worked in the commercial real estate space, representing local developers acquiring off market properties and partnering with local developers such as Castillo & Company, Contemporary Home Remodeling, and L&M Real Estate Investments, LLC to provide quality and affordable homes. 


Shabnam graduated from Boston College and Suffolk University Law School. She also received a Certificate in Diversity and Inclusion from Cornell University.
