Hi, my name is Mike Winsten, and I would like to be your healthcare and business attorney. I have been practicing law in the State of California since 1986 with several of Southern California's most prestigious corporate law firms until I founded my own firm in 2000. My clients have ranged from publicly-traded Fortune 500 companies to privately-held corporations and their key executives and shareholders. I regularly handle litigation and regulatory matters, often involving millions of dollars.

My business litigation practice includes jury and bench trials in both state and federal courts, as well as arbitration and mediation. My firm utilizes computerized litigation support technology, imaging, and databases when appropriate for document and/or image-intensive cases, and my billing system is LEDES and Legal Tracker compliant.

My business mission is to provide cost-effective legal and business solutions to my clients, with an emphasis on scholarship, common sense, ethical advocacy, and effective communication with clients and adversaries. All of my litigation clients want their cases settled, and almost all of my cases do settle before trial, some early in the process, others at differing stages leading to trial. Occasionally, for various reasons, cases do not settle and they proceed to trial. My business litigation jury trial experience is quite extensive, and this real-world courtroom experience and business litigation jury trial experience has enhanced my ability to vigorously and efficiently prosecute, defend and manage cases to settlement or verdict and judgment. I effectively counsel my clients regarding their expectations and offer a true continuous assessment of their cases, a skill that can only be learned by the first-hand experience.

I represent and counsel companies and individuals in numerous industries, with a primary focus on healthcare, real estate development and finance, and high technology. I have accumulated a great deal of experience and expertise in litigation, transactions, and counseling in the following industry sub-segments: healthcare finance and reimbursement, franchise relations, trade secrets, unfair competition, technology licensing, corporate ownership and management, probate, employment, and non-profit corporate governance. I also regularly serve as co-counsel with several of Orange County's leading family court lawyers with high net worth clients involved in marital dissolutions entangled with significant business ownership or management implications.

My wife, Cheryl, and I live in San Clemente, California. We are the proud parents of five incredible children - Chelsea, AJ, Ariana, Michael, and Ryan.
