Who We Are
About Olive Branch Counsel
A Texas-based estate and tax planning law firm focused on helping individuals and families protect what matters most.
About the Firm
What sets Olive Branch Counsel apart is the depth of experience we bring to every engagement — and the personal attention we give to every client. Our practice is shaped by decades in private family office advising, big-firm legal counsel, and financial planning, combined in a boutique setting where you always know who is handling your matter. We believe estate and tax planning works best when it is proactive, clear, and built around your life — not a template. Whether you are planning for the first time or refining a complex structure, we are here to guide you with honesty, precision, and genuine care.
