Ken Sigelman J.D., M.D.

Ken Sigelman J.D., M.D. is a serious personal injury and medical malpractice lawyer in California who is absolutely committed to seeking justice and obtaining fair compensation for the children and families he represents. Initial consultations are always free of charge. If Ken accepts the case, lawyer’s fees are on a contingency basis. Fees are owed only if you win, and are based on a percentage of the money recovered. In cases involving children, the court generally must approve the lawyer’s fees as fair and reasonable.

The insurance companies that defend healthcare providers, trucking companies, drug manufacturers, etc. are willing to spend virtually unlimited amounts of money on high-priced medical malpractice insurance defense lawyers and expert witnesses to defeat your medical malpractice case. Ken Sigelman J.D., M.D. commits all of the resources necessary to keep the playing field level; even it is means spending $100,000 or more to prepare the case as strongly as possible.

The final, and perhaps most important, aspect of commitment to clients is compassion. Ken and the entire staff at Kenneth M. Sigelman & Associates understand, empathize with, and deeply respect the emotional and financial sacrifices required of families under these circumstances.



Mark Birmingham

Mark spent the first 27 years of his career representing doctors, hospitals and other healthcare providers in medical malpractice lawsuits. He retired from practicing law in 2014 to operate a small franchise business for the next 3 years. Mark eventually realized he missed the unique challenges of working as a trial attorney in medical malpractice cases, but he decided he would not return to working as a defense attorney. He had no desire to work for insurance carriers and public entities, as he had for his entire career. Instead, he was determined to represent plaintiffs in medical malpractice cases to seek greater satisfaction from his practice.

Mark connected with his former adversary, Ken Sigelman J.D., M.D., in 2017 and his timing was fortuitous. Mark now receives tremendous gratification in using his extensive experience as a defense attorney to gain each and every advantage on behalf of the firm’s clients.
