About Us

How it Started

Sensei was established in 1997 by Sharon D. Nelson, Esq., a practicing attorney, and John W. Simek, who holds a wealth of technical certifications. Within a few years, Sensei had a national reputation as a boutique provider of IT, cybersecurity and digital forensics services.

While Sensei initially attracted law firms because of Ms. Nelson’s knowledge of the legal world and legal ethics, Sensei quickly grew to serve many kinds of businesses and organizations.

As nationally known speakers and authors, Sensei’s principals continue to educate audiences across the nation about IT, cybersecurity and digital forensics.
