Attorney licensed in California, New York, and Florida with over a decade of experience in technology transactions, data privacy, and intellectual property.

I hold the CIPP/US and CIPP/E privacy certifications and regularly support clients on matters involving data use, privacy considerations, and contract structuring in technology-driven business relationships. My approach is practical and business-focused, with an emphasis on clear guidance, efficient negotiation, and helping clients move forward with confidence.

As an attorney licensed in California and currently practicing remotely from Ohio, my primary focus is on drafting and reviewing prenuptial and postnuptial agreements. I offer help in drafting or navigating these agreements, ensuring they are tailored to each client's unique situation and needs.

Additionally, I provide services in wills and trusts, along with other legal areas, to offer comprehensive solutions to my clients.

Clear, strategic legal guidance when you need it most—whether you're planning ahead or defending a position. Legal challenges shouldn't feel confusing or overwhelming. Whether you're building an estate plan, structuring a business, or navigating a dispute, my practice is built on clarity, care, and practical strategy. I work with clients who want real solutions—not just paperwork—through planning and advice that truly fits their goals, families, and businesses. Planning & Structure I focus on estate planning, asset protection, and business succession, helping individuals and entrepreneurs organize their assets, reduce risk, and prepare for every stage of life. Whether you're setting up your first living trust, shielding your business from liability, or updating an existing estate plan, you'll receive clear guidance, fixed-fee pricing, and responsive support from start to finish. Each plan I design is tailored to your real-world priorities: preserving wealth, avoiding unnecessary taxes and probate, and ensuring the people you love are protected when it matters most. I also focus on general business matters outlined below. Disputes & Defense When legal conflicts arise—disputed contracts, demand letters, settlement negotiations, or litigation decisions—I provide realistic risk assessment and strategic guidance. I help clients understand their actual exposure (not just best-case scenarios), identify leverage points, and navigate toward efficient resolution. If you're facing a legal claim or need to evaluate your position before responding, I can walk you through the realistic options and their costs.
