About me

I am a family law attorney in Clinton, New Jersey where I am a partner at Gebhardt & Kiefer.  I am a Certified Matrimonial Attorney.

 In addition to practicing law, I devote a lot of time to additional community activities.  

In 2012 I was nominated to the Hunterdon County Bar Association and currently serve as President-Elect.  

I have the pleasure of serving as a Board Member of the United Way of Hunterdon County.

I have been nationally ranked and recognized as a Top 10 under 40 family law attorney and Ten Best under 40 client satisfaction award.  In 2015, I was named as a new leader to the Bar.
