Q. How has your professional experience shaped your thinking about your area of expertise?
Most high net worth individuals have worked hard to accumulate wealth. At some point in their lives, they want to transfer their wealth and accomplish that in the most tax efficient way, while still achieving charitable goals.

I have come to understand that family issues, real or perceived, are the product of a lack of communication between generations. Too often none of the heirs truly know what the decedent wanted, and this typically creates unnecessary conflict.
Q. How do you help your clients solve these challenges and meet their goals?

Throughout my 20-year career, I have encountered many family dynamics and the associated issues that go along with them. My approach is casual and focused on what’s important to my client and how I can best serve them. Discussing death and taxes isn’t enjoyable, but it can be done productively and proactively.

I listen carefully to understand my client’s goals, criteria and priorities. I establish a plan that addresses and accomplishes these principles in a tax efficient way, collaborating with their estate attorney and other advisors to ensure their best interests are at the forefront. Then I craft and deliver a powerful, yet individualized, estate plan to meet their needs. I provide peace of mind to my clients that their financial and charitable wishes will be accomplished. In addition, they receive comfort knowing that their wealth is being transferred tax efficiently to provide a majority of their assets to their beneficiaries and charities of choice.

Q. What is your favorite client success story?
One that comes to mind was for a family business where the first generation was the sole shareholder, despite all four adult children working in the company. They had charitable desires along with a wish to keep the business in the family. However, no successor was determined, and little communication had occurred.

After meeting with all parties individually and collectively, I helped open the communication and create a plan. By the end of the year, the business was transferred at a discount to the children, through a sale to Intentionally Defective Grantor Trusts (IDGTs). In addition, the parents created a private foundation and a board consisting of three generations, to educate the second and third generations on the importance of giving and investment management.
Q. What has been your greatest lesson learned over your career?
Let your clients talk, and listen to them. Really hear what they want and what’s important to them. Don’t assume their goals based on similar facts or patterns of other clients.
