Strategies designed to help you achieve your goals

As a client of the Private Banking and Investment Group at Merrill Lynch, you have access to services and resources ordinarily reserved for the world’s largest institutions. We work with individuals, families spanning multiple generations, business owners and executives. Using a goals-based wealth management approach, we put our clients at the center of every personalized strategy.

Our Approach

A Different Caliber of Experience

The RKMS Group provides wealth management strategies and offerings to a distinguished national clientele. Led by four principals, our team offers a depth of leadership that facilitates robust and informed responses to the challenges of significant wealth. We foster open communication to advance long-term client priorities, drawing on our complementary knowledge and skills, in-depth experience and refined service ethic.

We are the only team within the Private Banking and Investment Group at Merrill Lynch that is headquartered in Westchester County, New York. A single source for integrated wealth management, we unite the resources and capabilities that clients require to preserve, grow and transfer wealth effectively.

Our team offers broad experience, deep resources and vibrant collaboration. Together, we look to serve clients with a care and precision that demonstrate our deep-seated interest in their well-being.

Our private wealth managers and financial advisors provide clients with a direct line to all the resources and capabilities of a truly global investment firm—in ways that are more in keeping with a small, very exclusive boutique-like atmosphere. Concierge services, family meetings, and private seminars and events are all part of the experience.

PRIVATE BANKING AND INVESTMENT GROUP

The Private Banking and Investment Group provides tailored strategies to help meet the distinct needs of individuals and families with substantial wealth. Clients are served with a boutique-like approach by teams of rigorously trained and experienced advisors who are skilled in working with wealthy clients, their families and businesses. Clients can enjoy a caliber of resources and future-focused strategies that is typically reserved for the world’s largest enterprises. 

MERRILL LYNCH

Merrill Lynch offers a broad range of brokerage, investment advisory and other services, including insurance and investment analytics. Our advisors are available to work closely with the clients’ other trusted advisors, including accountants, attorneys and tax specialists. We can provide access to trust and estate planning services through Bank of America specialists.



"The horizontal structure of our leadership team enhances the client experience through fresh insights and a multi-layered perspective. Clients appreciate the one-on-one relationships they develop with each of us."

Private Wealth Manager

Catering to the Needs of a Select Group of Families

We are privileged to work with clients who have achieved extraordinary success. We help them navigate critical junctures in their financial lives, applying the skills, resources and acumen of our collective team.

We work with a diverse clientele, many of whom are senior executives, entrepreneurs and family offices. Because we exclusively advise ultra-affluent clients, we are intimately familiar with the nuances that significant wealth can entail. We focus our efforts on a limited number of clients, looking to serve them with an intensity and intimacy that underscore their importance to us.

Many of our client relationships span decades and involve multiple generations of families. Referrals constitute the crux of our business, and client satisfaction is paramount to our success.



"Continuity and longevity are hallmarks of our approach. We work with the children—and even the grandchildren—of clients we have known for decades. Real relationships are the core of our connection."

Robert Matluck
Managing Director
Private Wealth Manager

Our Deep Involvement in the Capital Markets

We are investors and pride ourselves on that distinction. Our proprietary investment programs target risk-adjusted returns, reflecting our decades of experience in research, analysis and execution. Our investment capabilities also encompass asset allocation and risk assessment—critical functions for high-net-worth investors. Clients value our hands-on experience in navigating challenging economic environments.

We believe that we drive value through our day-to-day involvement in the capital markets. By staying apprised of market themes and movements, we heighten our flexibility and responsiveness. We look to capitalize on opportunities by applying a nimble and informed perspective on changing conditions.



"Clients look to us for capital preservation and smart growth. Our direct interaction with the markets allows us to focus on these objectives while applying time-sensitive tactics and strategies."

Lee B. Konopka
Managing Director
Private Wealth Manager

Attuned to Client Needs

Clients have multiple dimensions of wealth: personal, professional and philanthropic. We help align all three, harnessing our experience, intellectual capital and the extensive resources of the Private Banking and Investment Group at Merrill Lynch to develop tailored strategies that culminate in cohesive action. We are highly trained and specially credentialed, but most important, we are resolutely focused on client outcomes.

Our offerings reflect our holistic approach:
  • Discretionary investment management
  • Concentrated and restricted stock strategies
  • Liquidity event strategies
  • Trust and estate planning services
  • Access to credit and lending through Bank of America, N.A.
  • Philanthropic strategies



"The clients we serve have complex needs and multiple priorities; we look to provide them with a seamless level of service and knowledge, addressing both sides of their balance sheets to identify efficiencies and tap into opportunities."

Todd A. Stankiewicz
Vice President
Private Wealth Manager
