Lease Assignment Agreement Lawyers for Santa Ana, California

I'm a California-licensed attorney with 18+ years of experience helping everyone from Fortune 500 companies and venture-backed startups to individuals navigating real-life legal situations. My career started at Fenwick & West, one of Silicon Valley's top law firms, where I worked alongside names like Google, Airbnb, Kleiner Perkins, and Sequoia Capital. From there I moved in - house at companies like Cloudflare, Autodesk, and Enphase - which gave me a practical, business-minded perspective that I bring to every client, no matter the size of the matter. Today I work with businesses and individuals alike. On the business side, that means commercial contracts, leases, startup corporate work, and serving as a fractional general counsel for companies that need a trusted legal partner without the overhead. On the personal side, I help individuals with employment matters, disputes, demand letters, contract review, and the kind of everyday legal situations where you just need someone knowledgeable in your corner. I'm direct, responsive, and I speak plain English — not legalese. Whether you're a founder closing your first deal or an individual facing a situation you've never navigated before, I'll give you the same level of attention and care.

I focus my practice on startups and small to mid-size businesses, because they have unique needs that mid-size and large law firms aren't well-equipped to service. In addition to practicing law, I have started and run other businesses, and have an MBA in marketing from Indiana University. I combine my business experience with my legal expertise, to provide practical advice to my clients. I am licensed in Ohio and California, and I leverage the latest in technology to provide top quality legal services to a nationwide client-base. This enables me to serve my clients in a cost-effective manner that doesn't skimp on personal service.

I graduated from Yale University magna cum laude, served as a Fulbright Scholar in Italy and attended UC Berkeley School of Law. In 2023, I was named a "Legal Visionary" by the Los Angeles Times. I have broad experience in corporate transactions and in serving as outside general counsel to clients. I started my legal career in Silicon Valley and Hong Kong working on large equity and debt financings and matters for private wealth clients. After returning home to Los Angeles, I advised startup companies with formations, acquisitions and day-to-day matters such as sales contracts and licensing. More recently, I have focused on data, IT and SaaS contracts for both providers and customers. My clients include NASDAQ-listed companies, a top ranked children’s hospital and local startups.

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.

With nearly a decade of in-house experience at publicly traded and high-growth technology companies, I bring a practical and business-focused approach to negotiating and managing a wide range of commercial agreements, including SaaS, licensing, procurement, and enterprise contracts. I lead strategic negotiations, advise on risk, and collaborate cross-functionally to support scalable legal processes. My background includes enhancing contract frameworks, refining templates, and driving alignment between legal strategy and business goals.

I am a San Francisco attorney with specific expertise representing the public with residential and commercial real estate interests in the Bay Area. I apply my background in dispute resolution services, contract analysis, and conflict management to identify and produce long-term results for clients amidst demanding and unforeseen circumstances.
