Partnership Agreement Review Lawyers for El Cajon, California

On this platform I have largely been helping people draft prenuptial agreements for many different situations as well as mediation/arbitration. I am an entertainment attorney by trade with experience in drafting and negotiating contracts in the fields of television, film, unscripted, music, and everything each entails. In addition, I have experience drafting and negotiating property leases and service agreements of various types. I am available for all types of contractual review or any drafting needs you may have.

Legal services cost too much, and are often of low quality. I have devoted my law practice to providing the best work at the most affordable price—in everything from defending small businesses against patent trolls to advising multinational corporations on regulatory compliance to steering couples through a divorce.

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. 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.

I hold a J.D., cum laude, from The George Washington University Law School and advanced technical degrees in chemistry and chemical engineering, which allow me to efficiently handle technically complex matters.

I have been a litigator in state and federal jurisdictions throughout the United States for the past 15 years, save for an eight-month stint as General Counsel and Chief Compliance Officer for a credit card processing company. I am an asset to any firm looking for support with any type of motion work or coverage for appearances, if necessary. I like to refer to myself as a self-proclaimed "walking code of civil procedure." I look forward to working with you and helping however I am able. Thank you for your consideration.
