As a family law attorney, I meticulously prepare my clients for and guide them through the intricate family court process with a goal of setting them up for success beyond this challenging phase.

My journey in family law began with an insightful clerkship in the Hennepin County Family Justice Center, where I gained a comprehensive understanding of family law from a judicial perspective. Over those formative years, I was deeply involved in a myriad of hearings and trials, offering me the invaluable opportunity to discuss cases with judges and draft critical court orders. This experience now underpins my approach at Henson Efron, where I leverage these insights to provide clients with realistic expectations of the family court process, how judges might perceive their cases, and the most effective strategies to achieve their objectives.

I focus exclusively on family law, addressing a wide range of matters including:

  • Divorce
  • Child Custody and Support
  • Spousal Maintenance
  • Orders for Protection
  • Post-Divorce Cases

My passion for family law is rooted in a deep-seated desire to support individuals navigating significant life challenges.
