Approach

Tab Image
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.

    Understanding Your Savings Vehicles
    When it comes to retirement savings, the most important thing is to get started - after all, time is one of your greatest assets. Although retirement may seem far for some, it is essential to get started on planning for future living expenses, potential education funds, or travel costs. Let us help educate you on ways to grow and preserve your wealth.

    The Psychological Transition into Retirement
    Most retirement preparations focus on financial planning, but it is equally crucial to look at personal considerations and help you with easing the fear of the unknown. Given that many people overlook the psychological adjustments of retirement, we can help you understand why it’s important to be emotionally (not just financially) ready for retirement.

    Risks to Your Retirement
    Once you determine what kind of retirement you want, we will work together to take a closer look at the risks that might be standing between you and your retirement goals. No matter how well you save during the accumulation phase, it's critical to plan how you convert those assets to income. We can help you navigate the challenges that may arise.

    Impact of Taxes
    The strategies you use when drawing down your retirement savings can have a significant impact on how much you’ll pay in taxes and may help you keep more of the returns. Each retiree’s situation is different but establishing a tax management strategy for your investments can help you retain more of your investment returns.

About Achilles Kontoyiannis

My name is Achilles Kontoyiannis, and I am a Financial Advisor in the Wealth Management division at Morgan Stanley located in Aventura, FL. Since the year 2020, I have been a Senior Vice President and Senior Portfolio Manager here. My practice is dedicated to domestic and international clients aspiring to preserve and grow their wealth. With over 30 years of industry experience, I focus on asset management, multi-generational planning, retirement planning, trust and estate planning strategy, and tax-sensitive investing.

As an entrepreneur, I have unique insight into the financial needs of my clients. My financial career began at Merrill Lynch as a Senior Financial Advisor. Then I spent seventeen years at UBS Financial Services as Senior Vice President and Wealth Management Advisor, where I had the opportunity to grow and evolve my business. In 2020, Morgan Stanley welcomed me and has supported my business by helping it thrive and offering its many resources to my clients.

Prior to entering the financial industry, I established my own successful apparel manufacturing business in Philadelphia, as well as a home furnishing business in New York City. This helped me understand the importance of financial security and having a plan that works for you. Whether you are undergoing retirement, a wealth transfer, or the sale of a business, my team and I will create a financial plan that is tailored to you and your loved ones. The “one size fits all” standard does not fit into my practice. All our goals are different, and that is why I create financial plans that reflect your personal goals and values to help you take control of your wealth.
