    About Me

    Mark Seruya
    Managing Director
    Senior Portfolio Manager
    Private Wealth Advisor

    For over 30 years, I’ve worked with high net worth individuals and institutional clients to help manage their whole financial picture. I have specific knowledge in all aspects of fixed income investing, with a particular focus on municipal, emerging market, corporate and U.S. government debt. Additionally, I advise clients on equity and alternative investment products, both through individual recommendations and through the selection of third-party managers. I also help many clients with lending strategies, providing access to the firm’s Private Bankers and Investment Bankers. I enjoy working with a broad range of clients and their extended families, and have an especially active client base of tech entrepreneurs and real estate magnates.

    I joined the partnership in 1988 at Bear Stearns, where I became one of the youngest employees in the firm’s long history to hold the title of Senior Managing Director. I was named to the Financial Times’ list of America’s Top 400 Financial Advisors in 2014 and 2016 and was also recognized as a Top 100 Wirehouse Advisor by Registered REP. magazine in 2012.

    Russell Ganz
    Managing Director
    Family Wealth Director
    Senior Portfolio Manager
    Financial Advisor

    Drawing on nearly two decades of portfolio management and financial planning experience, I advise clients on the management, preservation and transfer of their wealth. I focus on fixed income portfolio management, particularly municipal bonds, and oversee the team’s fixed income, equity and balanced portfolios. Our group creates and customizes separately managed investment accounts on a fully discretionary basis, with a strong focus on asset allocation and risk management. I have also earned the Morgan Stanley Family Wealth Director designation, providing our team access to an extended suite of resources to address complex needs such as financial planning, insurance and multigenerational wealth and estate planning.

    I joined the team in 1997 at Bear Stearns, where I held the title of Managing Director, after originally entering the industry in 1996 as a fixed income trader focused on municipal bonds. I began my career as an attorney, specializing in securities and antitrust litigation. I hold a B.A. from the University of Michigan and a Juris Doctor from the University of Miami School of Law.

    David Berdon
    Managing Director
    Portfolio Manager

    Serving as Sage’s Portfolio Manager, I construct and deliver portfolios customized for each client’s unique investment objectives. I bring almost 25 years of investing and financial markets experience to the task. Most recently, I headed Morgan Stanley's Wealth Management Research department, where I managed a team of 125 professionals responsible for creating and delivering investment advice to the firm's 16,000 advisors and $2 trillion in client assets. My responsibilities spanned global asset allocation, product research and asset manager research for mutual funds, ETFs, and alternatives including private equity, private real estate and hedge funds. I also served as CEO and Board member of Morgan Stanley’s $6 billion publicly traded CGCM fund family.

    Before joining Morgan Stanley, I spent 12 years at Goldman Sachs & Co., where I was a co-portfolio manager for $35 billion in institutional equities. One of the funds I co-managed , Goldman Sachs Large-Cap Value, was named the #1 fund in its category in 2004. I earned an MBA from the Wharton School at the University of Pennsylvania and a B.A. in government and law from Lafayette College.
