Our Experience – Your Advantage

Dr. David Lewin is the founder and president of Statistically Speaking Consulting, LLC.  He graduated summa cum laude from Cornell University with a degree in Operations Research and Industrial Engineering.  He later earned his Ph.D. in statistics from the Wharton School at the University of Pennsylvania.

In addition to his academic training, he has professional experience working in supply chain management and pharmaceutical biostatistics at Johnson & Johnson, biostatistics for the psychiatry department at the Mount Sinai School of Medicine, and as the director of statistics for the Philadelphia Eagles.    

The breadth of applications and industries that he is familiar with is expanded by the consulting opportunities he has had over the past nine years involving pharmaceutical clinical trials, consumer product R&D, consumer research, statistical methodology development, manufacturing quality, and sports.

David attributes his ability to effectively communicate these technical concepts to his experiences as an educator.  He taught high school math, including advanced placement statistics and computer science, and has tutored numerous undergraduate and MBA students.

After many years on the East coast, he now lives back in his hometown of Chicago with his wife Lynn and 3 children (Ali, Kai, and Joy) and their dogs Philly and Bora.
