Reviews: “Dr. Halperin supported our legal team by providing great testimony and giving invaluable help in preparing to question the opposing expert. He was professional and helped to clarify weaknesses and potential landmines in our case. I cannot recommend Dr. Halperin more highly.” David A. Kallman, Attorney at Law Kallman Legal Group, PLLC Lansing, Michigan "I received fantastic expert testimony and other scientific support from Dr. Halperin for my legal case related to a Covid vaccine. If a similar need were to arise again, he is definitely whom I will be reaching out to. Dr. Halperin is personable, timely, and simply outstanding in every way. I tried contacting many other experts for assistance, and he was the only one that came through for me. I could not be more grateful." Angela Loerzel Swafford, LCSW, BCD, ACHP-SW, Portland, Oregon
