Alan J. Sedley draws on his invaluable experiences while serving as corporate in-house general counsel to two large California hospital health systems to compliment his thirty-plus years as a private law firm healthcare attorney. During his years in-house, Alan performed work on a wide array of legal projects pertaining to corporate business issues at the health system level, while managing transactions, litigation, regulatory compliance and operational processes at the hospitals.

Through private practice and as retained outside counsel, he regularly advises and represents hospitals, health systems, physicians, NPs, PAs, ambulatory surgical centers and multi-specialty medical groups in their oft-challenging operational issues, addressing the traditional business and legal concerns within the context of the healthcare marketplace.

Experienced Medical Staff Counsel

Over years of healthcare law practice, Alan has pursued a specialized focus and offers highly experienced and dedicated counsel to large medical group and hospital medical staffs on issues including; medical staff credentialing, privileging, and recruitment, peer review analyses arising from suspected practitioner clinical deficiencies or disruptive conduct, peer review body and committee investigatory processes, and detailed guidance on peer review hearing procedures as well as statutory reporting requirements. He provides his expertise to the analysis and revision of medical staff bylaws and policies and procedures. Alan has been retained and has testified as a peer review expert witness in civil trial, offering his expertise on peer review due process requirements as applied to federal and state regulatory schemes.

Laser-Focus on Civil Litigation and Administrative Proceedings

As an experienced civil litigator with a proven track record of success in all phases of court civil trials and binding arbitrations, Alan’s client-focused strategies and depth of experience also come into play through his efforts to resolve matters efficiently and expediently without needlessly exposing his clients to the uncertainties and costs often associated with litigation through use of his honed analyses skills and mediating and negotiating techniques.

In addition to representing health care providers in commercial litigation, Alan has successful litigation experience ranging from the defense of employers in complex sexual harassment matters to litigating medical malpractice claims. He has successfully litigated cases in federal district court on behalf of hundreds of hospitals nationwide, initiating civil suits against the Centers for Medicare and Medicaid alleging its misapplication of federal rules and regulations, the results of which provided payment of hundreds of thousands of dollars in additional Medicare program reimbursement that had been initially withheld from those hospitals.

Able to navigate the complexities of administrative law, Alan has a track record of successfully representing physicians and other healthcare professionals before California regulatory and licensing boards and agencies, aggressively defending clients through the investigatory and administrative hearing phases, all the while maintaining a keen focus on the ultimate goal of preserving a client’s hard-earned license and enabling him/her to continue professional pursuits.


Since 2017, Alan has been selected annually to Southern California Super Lawyers and has received the Martindale-Hubbell ‘AV Preeminent’ Rating. He is honored to have been selected to serve key leadership roles at various community based organizations, including the boards of the San Fernando Valley Bar Association, Temple Aliyah, Israel Cancer Research Foundation, West Hills Hospital, United Synagogue and the Los Angeles County Citizens for Veterans. Having been certified in bioethics studies, Alan instructed oncology fellows at St. John’s Hospital annually through a six-month focused curriculum of health law and bioethics. He has been qualified to serve as a peer review hearing officer through the California Society of Healthcare Attorneys.

Frequently called upon to speak on health law-related topics, Alan enjoys the challenge of educating and training a variety of health care professionals and associations, including engagements with hospital and large medical group medical staff leaders, hospital administrators and medical societies, law schools and bar associations.

Life Outside the Firm

When not immersed in the myriad of challenges occasioned by healthcare law practice, Alan loves to hike local mountain trails, and is avid indoor and outdoor cyclist. While he pursues his dream of someday becoming a well-respected amateur photographer, he is focused on providing mounds of love and bits of offbeat humor to his three adult children and two young grandsons.
