Welcome

My name is Mark Allenspach and I lead a St Louis-area Private Wealth Management team that serves a national clientele of ultra-high net worth families and individuals.  Most of our clients are either senior executives or entrepreneurs who have accumulated significant wealth in the form of concentrated stock positions.  We have extensive experience in developing strategies to manage these positions within the context of comprehensive wealth management plans tailored to their needs, goals and challenges. Whether you are navigating the complexities of executive compensation, investing the proceeds from the sale of your business, defining a philanthropic strategy or creating a legacy for your heirs, I can serve as the first-call advisor who helps you understand the issues and make solid financial decisions.  Combining my own knowledge and experience with the vast global resources of Morgan Stanley, I will deliver solutions to you and your family in the way that is most appropriate for how you invest and what you want to achieve.  You will have access to some of the worlds most seasoned and respected investment professionals, a premier trading and execution platform and a full spectrum of investment choices. I look forward to discussing your challenges and aspirations, and the giving you the resources needed to help ensure your financial goals are accomplished.

1 Morgan Stanley Wealth Management, December, 2024

Source: Barron's.com (May 2024) 2024 Barron's Top 250 Private Wealth Management Teams awarded in 2024. The teams are ranked on a variety of factors, including their size and shape, their regulatory records and credentials of their members, and the resources they have at their disposal to serve their client bases. The rankings are meant as a starting point for clients looking for an advisor—a first-pass vetting that can help investors narrow a search. Every advisor will have his or her own approach to investing, financial planning, and other services. Clients are encouraged to approach a search for an advisor the way they would a search for a doctor—interviewing multiple professionals and getting opinions from multiple third parties. Rankings are based on the opinions of Barron's and this ranking may not be representative of any one client’s experience. This ranking is not indicative of the Financial Advisor’s future performance.

Approach

Discovery Process
Investing the time to learn about you and your family; your assets and liabilities and the risk exposures, enables us to formulate strategies and customize the relationship to your needs.
Formulation of Tax, Trust and Estate Strategy
Working with your tax and legal advisors, we help analyze your income and estate tax circumstances to identify and tailor planning techniques that may be used to address your objectives.
Creation of Customized Strategic Asset Allocation
Your customized asset allocation reflects risk, opportunities and taxation across multiple entities, while integrating your investing and estate plans.
Integration of Tactical Asset Allocation
Short-term adjustments seek to capitalize on temporary market distortions. Before making adjustments, we analyze the impact of taxes and trading costs on potential returns.
Implementation of a Customized Wealth Strategy
After comprehensive due diligence and analysis of expected results across multiple market scenarios, strategies are chosen from our expansive investment platform.
Ongoing Assessment
In coordination with your other advisors, we can conduct ongoing reviews and comprehensive reporting to ensure that your strategy adapts to changing financial and family needs.

Clients

Tab Image
As of March 2025, we manage over $2.1 billion in assets for a select clientele of approximately 36 highly accomplished executives, entrepreneurs and their families.  Virtually all of them created the vast majority of their own wealth, and most are still actively engaged in the businesses they lead.  They tend to be highly active in their communities, passionate about their interests and deeply committed to the wellbeing of their families.

Though most are financially sophisticated, our clients often lack the time and specialized expertise to handle the complex, multifaceted challenges of managing significant wealth.  Our role is to provide, or provide access to, the full range of experience and resources to address all of these challenges so our clients are free to focus of their next pursuit, whether that is family, a new business opportunity or building a philanthropic legacy.
