    Adam Zielinski, BFATM


    Adam made his first stock trade at age eleven, and while he earned just a few bucks on it, he became fascinated by the world of investing. Since there was no one in his family who worked anywhere near Wall Street when it came time to apply to college he decided to go where the action was and attended NYU’s Stern School of Business.

    Adam’s family set him up for success in other ways, being the interpreter as a child for his deaf parents set Adam on a lifelong path to helping people. It also helped him become a patient, active listener, one of his strongest attributes.

    Adam considers himself lucky to have traveled the world and has special memories from visiting Chile, Argentina, and South Africa while a student. His love of working with a diverse group of people probably started there. Upon graduation Adam was drawn to the institutional world of finance, starting in Investment Banking at Greenhill followed by working on a trading desk at Citigroup. However, he quickly learned the work-life balance that comes with working with the world’s largest corporations was not what he ultimately wanted and made an early pivot to working with individuals and families.

    One of Adam’s best career decisions was accepting the invitation to co-found Millstone River Wealth Management, LLC with his partner Matt Siegel. The firm specializes in guiding its clients to help them reach their most important goals.

    When Adam isn’t supporting his clients and their families, he’s spending time in Asbury Park with his wife Laura and their daughters, Josie and Edie. He is a recently converted Monmouth Hawks college basketball fan and he likes to say that he loves good food but doesn’t mind bad food.
