LENZE | LAWYERS  is proud to have the unique distinction of being a women owned, women led law firm. As a firm, we strive to adhere to the fundamental premise that providing the highest level of service to the client is the foundation of a successful legal practice. The strong representation we provide our clients comes from our preparedness, grace and civility.

Our focus is mass tort pharmaceutical drug and device defect litigation, as well as personal injury cases, employment litigation, medical malpractice and other types of law wherein individuals are unjustly harmed. We believe in providing a compassionate ear and strong voice on behalf of all of our clients. 

Our founding partner, Jennifer Lenze, has been recognized as a Top 40 under 40 Trail Attorney by The National Trial Lawyers. Top 40 under 40 is a professional organization comprised of America’s top young trial attorneys.  Membership into The National Trial Lawyers: Top 40 under 40 is by invitation only, and is extended exclusively to those individuals who meet stringent qualifications and specialize in the legal practice of criminal defense or civil plaintiff.


LL began following the death of Jennifer Lenze's former partner, J. Paul Sizemore (1970-2014), a recognized trial lawyer who provided exceptional representation on behalf of injured clients. Paul instilled in her the core values of civility in advocacy, tireless commitment, and compassion for those who have been wronged. These principles have inspired the vision for LL.
