My team's hallmark is stewardship in wealth management. We make an unwavering commitment to serve clients with dedication, diligence, and genuine care. Technically, we focus on engineering portfolios with high sustainability regardless of market or economic conditions, aiming to capture and retain consistent stair-step economic benefits despite the market’s unpredictability. Our rules-based, market-adaptive, and risk-controlled strategies are tax-aware and designed to filter market noise and provide a capable navigation of market-regime shifts. In addition, we use advanced computer models in developing a full-range financial strategy that incorporates all elements of clients’ financial lives.

In our team we have a deeply-rooted tradition of participating in the communities we serve through both organizational volunteering as well as direct, personal involvement.

Where do we begin? It starts with you.

At Merrill Lynch Wealth Management, your financial advisor focuses on the things you care about most- family, goals and priorities - even as they change over the years.

Understanding Your Life


I believe that the creation and cultivation of wealth is a distinctly personal as well as a broader civilizational imperative. As such it needs to be pursued with the utmost seriousness, skill, and dedication. In my team we consider the clients’ wealth to be sacred, and we set as our mission not only to safeguard it watchfully but also to grow it – responsibly, sustainably, and even aspirationally. We approach this task with both reverence and diligence, bringing to it decades of vigorous schooling and training as well as many years of hands-on experience.

Our Philosophy

Guiding Principles

Today it has become commonplace to refer to a ‘goals-driven’ orientation in wealth management. While this reflects an important improvement across the industry, I believe that the focus on it is still misplaced. 
Of course wealth management must be at all times client-centric and goal-supportive, but I believe that it should first and foremost be market-aware. This is because the market can at times be unsupportive of your goals, and also because your goals are rarely static – they evolve organically and can be reshaped externally in ways that are tough to predict. Instead, I believe that wise wealth management ought to actively navigate the markets, seeking to capture and retain for you maximum stair-step benefits out of its gyrations through the use of market-adaptive, risk-controlled, and tax-aware strategies. This will allow your wealth to not only support your goals, but even inspire their evolution.

Our Approach

I believe that capital is the monetary manifestation of accumulated progress and the fuel of future aspirations, and therefore it requires vigilant preservation and tenacious cultivation.

Rooted in this philosophy, our approach to wealth management capitalizes heavily on the technical aspects of my quantitative education and training, and was further forged in the academic, corporate finance, and portfolio management roles of my career.

This pedigree has bestowed a distinctive character to the way we work with, advise, and invest for our clients, and sets us apart in both areas of our practice - wealth strategy and investment management, as outlined below: 
Our Wealth Strategy Discipline
In my team, we start the collaboration with our clients by engaging in a thorough exploration of their financial lives, including their status and objectives, preferences, passions, as well as their overall vision of the future. Many wealth managers readily derive from that exploration an investment plan, but we beg to differ in two important ways:

First, we believe this exploration is inactionable unless it is embedded in a realistic and creative view of the market dynamic. The market is not a blank canvass for investor aspirations, and so we find “goals-driven” financial strategies to be “voluntaristic” (part wishful, part willful). It is not only that some plans may not achievable but, far more importantly, many achievements that are possible will be left unattained without an insightful view as to what can be wrestled out of the market workings with good management.

Second, while many wealth managers rely on forecast-based simulation tools to build financial strategies that marry the client vision with the market dynamic, we are aware that such assumption-driven and normative tools have many limitations and we are skeptical of their realism and utility. In contrast, we prefer to use sophisticated “aft-cast” models that are free from economic, asset, and statistical assumptions, allowing us to stress-test with historical realism a great variety of contextually complex pathways of wealth formation. In this way we create actionable financial strategies that open up new horizons for our clients and remain resilient across market cycles.

Our Investment Management Methodology
I believe that while the capital markets are our civilization’s most powerful engine of wealth creation, they are not necessarily benign or benevolent at all times. Moreover, the markets can behave in ways that are atypical to their long-run historical averages during the investors’ particular tenure. Owning to that, we remain at all times unbiased and agnostic. We eschew the temptation to forecast the markets – an exercise that many studies show is rather futile – but instead practice watchful adaptation and vigilant risk management – two modalities that human intelligence excels in. Owning to that, our portfolios maintain an unconstrained orientation - in particular:

We do NOT practice “buy-and-hold,” since we find that markets are not constantly random, but exhibit tractable regime shifts.
We do NOT adhere to the ideas of “strategic asset allocation,” since we find that asset class payouts are not fixed, but vary by market regime, and one cannot practice true active management within the fixed targets of strategic asset allocation.
We are NOT “tactical asset allocators” since we find that markets are not continuously trending, and most shifts end up being transient and mean-reverting, reflecting pure market noise.
NEITHER do we espouse “matrix investing” since we find such portfolios architectures (like Size & Style or Sector Blends with Over-/Under-Weights) to be dilutive and blind to market-regime shifts. 
Instead, we build our strategies with the goal of harnessing multiple sources or ‘factors’ of returns - like Market Exposure, Momentum, Value, Quality, and Low Volatility - in an integrated way. In doing so we are guided by the overarching principle that market activity is dominated by noise which, when left unfiltered, masks the actionable signals of impactful regime shifts.  
Our strategies use proprietary rules-based tools to filter out the overwhelming noise that dominates the market activity and identify and capitalize on actionable signals of impactful market-regime shifts. Armed with those signals, our strategies are engineered to harness multiple return factors while minimizing the impact of the well-known instabilities that characterize the productivity and expression of those factors across the market cycle (e.g. Bear Markets, Value “traps”, Momentum “crashes,” etc.).

It’s our strategies' mission to wrestle out of the market gyrations consistent stair-step wealth benefits for investors, and we commit steadfast to pursuing it with diligence and excellence.


Using the broad investing resources of Merrill, I can also assist with income management, education funding, retirement planning, and guidance for executives with concentrated stock positions, traditional and alternative investments, wealth transfer and estate planning services. And with your permission we can also work closely with your other professionals, such as attorneys, accountants and other specialists, to help you pursue your goals.
