Jennifer H. Diggles


My entire life I have been driven to, and am deeply passionate about, both working with people and being a perpetual learner. Practicing as an OUI attorney allows me to continuously learn and better my understanding of the law. OUI defense is multifaceted, involving not only an individual’s constitutional rights but also intricate scientific concepts that are constantly evolving. It is important that OUI attorneys develop an understanding of these concepts as they relate to breathing and blood testing and the admissibility of those tests in OUI cases. As a new attorney, I am privileged to be working with Attorney Bernard, who is at the forefront of these issues in Massachusetts and has in-depth knowledge of the science behind them.

Each client is unique, each case involving different facts and circumstances and requiring an independent approach. However, one thing is constant – your right to the best possible defense. I am here as part of a team that will take the time to get to know you, thoroughly analyze your individual situation, explore every possible avenue of defense, and guide you through the entire legal process.

Prior to OUI Defense

Life has led me down many roads where my role has varied dramatically – from being first on the scene of emergencies as a firefighter medic to working intimately with those suffering from addiction as a substance abuse counselor to now protecting individuals’ constitutional rights as an OUI defense attorney. These combined experiences have helped me develop the ability to connect with people on a personal level, listen with empathy, and recognize that each person’s situation is unique.

I received my bachelor’s degree from the University of Texas-El Paso and a Master’s degree in Addiction Studies from the University of South Dakota. I then pursued my J.D. and graduated magna cum laude from Western New England University School of Law. I am admitted to the Bar in Massachusetts.
