Sean L. Robertson | Attorney

Sean Robertson is the Founder and CEO of Gateville Law Firm, a boutique practice specializing in sophisticated estate planning, tax strategy, business succession, and asset protection for high-net-worth individuals, business owners, real estate investors, and seniors. With over 22 years of experience and an advanced background in tax law and asset protection strategy, Sean is passionate about helping entrepreneurs and families who have built significant wealth protect their assets and transfer their legacy to the next generation. He loves what he does, and that passion comes from understanding that estate planning is not really about documents. It is about relationships, families, and being there when times get challenging—especially in moments of death, incapacity, or major life transition. Recognized as a Best Law Firm by Best of Fox Valley in both 2024 and 2025, Gateville Law Firm is proud to serve the Yorkville community.

A Business-Minded Approach
Unlike many attorneys who approach legal matters in isolation, Sean understands that business reality and practicality go hand in hand with legal strategy. He has worked extensively with entrepreneurs, business owners, and real estate investors navigating growth, scaling, and operational challenges. His extensive background in commercial real estate transactions gives him unique insight into how to structure and protect diversified assets while supporting business growth. More importantly, he understands the emotional weight of protecting what you have built.

Practical Experience When It Matters
During the 2008–2013 recession, Sean worked extensively with small business owners, families, real estate investors, and commercial property owners facing unprecedented creditor pressures. He witnessed firsthand the fear families experience when an economic crisis threatens decades of accumulated wealth. His experience demonstrated that asset protection is not theoretical. It is essential, life-changing work that preserves not only wealth but also peace of mind and family security.

Sean brings over seven years of significant experience in divorce and family law matters. His hands-on experience with contested asset protection, child support and spousal maintenance issues, and custody matters gives him practical insight into asset protection that goes far beyond planning theory. As a married father navigating a blended family, he personally understands the unique complexities blended families face. This experience informs his deep commitment to helping families navigate complexity with clarity and care.

Comprehensive Wealth Planning
At the core of Sean's practice is comprehensive estate planning using wills, living trusts, and strategic structures designed to avoid probate, minimize taxes, and ensure families' assets transfer smoothly. Sean knows the real work happens when he helps clients think through their deepest concerns: How do I protect my children's future? What happens if I am suddenly incapacitated? He develops personalized estate plans that address these human concerns—whether protecting assets for beneficiaries, providing for blended families, ensuring business continuity, or planning for long-term care needs.

His deep expertise in tax planning and asset protection—including Series LLCs, land trusts, and holding companies—combined with his rigorous tax background enables him to develop comprehensive plans that preserve wealth and position it for growth and efficient transfer.

A particular focus is protecting seniors from the devastating financial impact of long-term care costs. He works proactively to develop strategies that preserve life savings while ensuring access to quality care.

Building Lifetime Relationships
Sean is committed to being a trusted advisor throughout your life—the attorney you call when circumstances change, when you face difficult moments, or when you need guidance. His goal is to become someone you depend on—someone who genuinely cares about your family's well-being and financial security.

A graduate of DePaul University College of Law and the University of Illinois at Urbana-Champaign, Sean brings both intellectual rigor and genuine care to clients' most complex challenges. He is committed to providing the expert guidance and reliable counsel you need to protect your wealth, grow your business, and leave a meaningful legacy for the people and causes you love.
