"It is during our darkest moments that we must focus to see the light".


Our Mission

At LightCore, our mission is to tenderly seek and narrate the deep connection between your being – who you are as a person with unique traits, characteristics and roles – to your actions. Our goal is singular: to provide the court with a personified appreciation of you through the use of a holistic and compelling narrative. We focus on you as a person and endeavor to balance the criminal act with emphasis on your positive attributes, personal history and remorse.

One of the unique draws of working with LightCore, is our access to a vast international network of professionals and experts. Our specialists are uniquely skilled in undertaking thorough record collection, careful review and interviews of key witnesses and experts, we work closely with you and your defense team to procure an individualized mitigation memorandum for your legal team.

Who we are

We are a team of professionals who specialize in criminal mitigation, advocacy in sentencing and parole with a restorative justice orientation. Our skilled specialists and advocates will provide you with comprehensive and effective support during this difficult and challenging time.

What we do

Our specialists undertake an individualized mitigation analysis in an effort to illuminate the unique circumstances surrounding your actions to inspire the court’s decision with as lenient a sentence as possible.

How Does Mitigation Help Your Defense?

Working with a mitigation specialist will add indispensable value to your legal process.  Research demonstrates, having a mitigation specialist on your team may help to achieve a reduced sentence. Criminal mitigation incorporates a focused exploration into your unique trajectory and individual characteristics. This unique analysis encompasses a wide cross-section of your life in an attempt to extract the varying types of specific circumstances that apply to your case. Lightcore collaborates and consults with your legal counsel to strategically procure your best possible outcome.

Some examples of common mitigating factors can include:

  • scope and extent of the role you played in the criminal action,
  • unusual circumstances,
  • extent of harm done,
  • lack of previous record,
  • relative necessity of the actions,
  • remorse,
  • presence of addiction,
  • difficult or traumatic personal history,
  • restitution etc.

At LightCore, our specialists have outstanding clinical and exploratory skills that will help your defense team to identify these factors.
