Lyn and Ralph Haber formed the partnership of Human Factors Consultants in 1987, and we work together on every case. We firmly believe that combining our complementary knowledge and skills provides better expertise than can a single expert, or a large firm of experts. Research has strongly documented that two heads working together are better than one. Our partnership is an instance: we offer the legal community the best consultative services and the finest understandably, scientifically based courtroom presentations available.

Ralph Haber, earned a Ph.D. in experimental psychology, and has 46 years of professional experience in psychology and human factors. He has received many honors and awards, and 25 governmental contracts and grants. He has published 7 books, 250 professional scientific papers, and given 100 conference and convention presentations.

Lyn Haber, earned a Ph.D. in experimental linguistics, and has 35 years of professional experience in psychology, linguistics and human factors. She has received 7 governmental grants and contracts, published 5 books, 50 professional scientific papers, and given 60 conference and convention presentations.
