About Me
A New Jersey native, Len graduated from Rutgers University with a BA in Economics and later earned a Masters degree in Public Policy from The University of Pennsylvania. He decided to combine his passions for finance and politics by beginning his career as a Public Finance specialist, advising local governments in New Jersey and Pennsylvania. Several years later, he started his own firm that provided equity and mutual fund analytics to investors seeking information on what funds and institutions were buying and selling. In 2010, Len joined Merrill Lynch and put his analytical skills to work in the service of clients and their families. “I derive great satisfaction out of adding value to my clients’ lives,” he explains. “The deeper the conversation, the more I’m able to understand what my clients really care about and how to help them proceed toward their goals with greater certainty and confidence.”
Len co-founded The Mangiaracina Stuart Group with Greg Stuart in 2016. The team finds it especially gratifying that many of their clients are passing them on like a legacy to their children and grandchildren.
Outside the office, Len is an avid golfer and served as Chairman of the Board for First Tee, an organization focused on youth development through the integration of golf with a life skills curriculum. He has also been an active participant in Leadership Montgomery County.
Len resides in the Kentlands in Gaithersburg with his two teenage daughters.

About Me
Greg collaborates with high-net-worth families, founders, and senior executives to bring order and intention to complex wealth. His practice is concentrated in the technology, government contracting, and real estate sectors, where compensation structures, liquidity events, and concentrated equity positions require precision and disciplined planning.
He regularly advises executives at top Fortune 500 technology companies along with leaders at emerging AI and privately held firms navigating pivotal growth phases.
Greg’s work centers on striving to help clients make confident decisions around:
• Concentrated stock and risk exposure management
• Equity compensation optimization (ISOs, NSOs, RSUs)
• 10b5-1 plan coordination
• Tax Efficient Liquidity event preparation and post-transaction planning
• Investment strategy integration with tax efficiency
• Retirement income design for executives and business owners
• Donor-Advised Fund Integration and Charitable Estate Planning
Where many advisors focus solely on investment management, Greg takes a broader strategic planning view. He aligns equity decisions, portfolio construction, tax considerations, and long-term retirement objectives into one cohesive plan. His approach is pragmatic, forward-looking, and built to reduce unnecessary risk while preserving upside opportunity.
Greg is known for simplifying high-stakes financial decisions and translating technical complexity into clear, actionable strategy — helping clients to move forward with conviction, not uncertainty.
A Maryland native, Greg graduated from Randolph Macon College with a double major in Business Economics and British Literature. He and his wife Amanda, a proud naval veteran and tech executive, often volunteer at the Walter Reed National Military Medical Center’s USO Warrior and Family facility. Greg is also an active member of The Bullis School Alumni Board.
When not advising clients and giving back to his community, Greg enjoys travel, golf and spending time with his wife and their two sons.

7Investing in the market entails the risk of market volatility. The value of all types of investments may increase or decrease over varying time periods. The returns on a portfolio consisting primarily of sustainable or impact investments may be lower or higher than a portfolio that is more diversified or where decisions are based solely on investment considerations. Because sustainability and impact criteria exclude some investments, investors may not be able to take advantage of the same opportunities or market trends as investors that do not use such criteria. Diversification does not guarantee a profit or protect against loss in a declining financial market.
