A natural resource for your wealth

Some of America's foremost energy and business professionals seek us out to help them design their portfolios and overall financial picture. When you consider what it takes to build and pass on significant, dynamic wealth, it's no surprise these clients need a different perspective, one that can adapt to the demands they place on themselves, their outlook and their resources.

Our wealth management advisors have years of experience helping bring greater structure, clarity and efficiency to key aspects of clients' financial lives. What's more, our advice, guidance and services are backed by the investing insights of Merrill Lynch and the banking convenience of Bank of America.

Exploring the possibilities of tomorrow
We think you'll find one of the strengths our team offers is helping you define and sharpen your vision of what you want your life—and lifestyle—to look like over the next 5, 10, even 20 or more years. Based on your individual goals, we help you create a blueprint for your wealth, one that details how your assets, income, insurance, spending and borrowing can all work together to support your objectives. This approach helps our team to make targeted recommendations on your short- and long-term investments, business interests and retirement and legacy planning strategies.

Strategies for the most sophisticated needs

If you're like most of the clients that we serve, your resources give you the power and the privilege to choose the kind of lifestyle you want—on your terms, on your timetable. We offer financial and investment strategies designed to help you actively pursue your goals.
Retirement outlook. Together with your outside tax and legal advisors, we can offer guidance on tax-minimization strategies to help structure your wealth in the stages leading up to retirement.

Monetizing equity compensation. For many clients, smart management of their employer stock holdings can be essential to preserving their wealth and fueling their retirement. We will work with you to develop sensible strategies to manage your holdings, based on your risk tolerance, time horizons, objectives, expectations for future growth, liquidity needs and tax considerations.

Wealth transfer services. Working with specialists from Merrill Lynch, and in coordination with your attorneys and accountants, we can help you develop an efficient wealth transfer strategy. We can guide you on trust investments, charitable giving, life insurance and other tactics to help you pass on your wealth the way you want.

A focused relationship built on understanding and shared information

We know that your assets are far more than just numbers on a balance sheet—they represent a certain lifestyle, a vision of the future and a legacy for the next generation. In helping you manage your wealth, we respect the efforts you've put into building affluence, and we work hard to demonstrate our integrity in everything we do.

Client-focused relationships. We're integrally involved in clients' financial lives, understanding their needs and constantly looking at how to exceed their expectations. Our service philosophy is simple: We build relationships, and we get things done.

Open communication. We want clients to speak freely with us. To work effectively on their behalf, we need to know about their assets, their goals, business issues, or impending family changes, retirement or health concerns. At their request, we also communicate with their legal and tax professionals, so that each one's strategy and service is coordinated.

Informed advice and guidance. Our strategies and recommendations are built on careful research, analysis and our understanding of market trends and tactics. We can show you the rationale for each course of action we propose, so you can make an informed decision.

Helping energy professionals power their futures

At The Mirabella Fenz Abalos Group, we focus on an extraordinary group of clients. They are some of the most dynamic and accomplished leaders in the energy industry and other businesses throughout Texas and across the country. By and large, they have spent lifetimes creating value, opportunity and a different level of affluence.

These clients have demanding goals for their wealth and their lives—and they need wealth management that can keep up with their changing outlook and perspectives. They want guidance from a trusted place, offered by people with the insight and know-how to help create the potential for a brighter tomorrow.

Coupled with the investing insights of Merrill Lynch and the banking convenience of Bank of America, our team can offer a degree of advice and guidance, service and experience that we believe few other financial teams can exceed.

While you may know our reputation, once you experience our level of service, we think you'll see why a select group of families and prestigious companies have chosen us—and stay with us.


Merrill is proud of our advisors who’ve received recognition from industry publications. We believe they are setting the standard for exemplary client service.

    *Peace of mind is an aspirational state of mind that clients hope to achieve. There are no guaranteed results following completion of the Goals-Based Wealth Management process because markets can fluctuate and investments can lose value. Merrill Lynch Wealth Management Advisors work with clients to help them understand how the goals based wealth management process can help to address their concerns, financial situation and priorities.

    Helping you reach your goals starts with getting to know you personally. Through understanding what matters most to you, we can help you create a financial strategy that reflects your personality. Only then can we offer an approach that is built around your life priorities and the ongoing advice you need to help you manage fluctuations in the market and changes in your life. Let’s work together to help you achieve your goals.
