Being the founding partner of this legal corporation was a long journey and one that is held in the highest regard.  

During my time in law school I gained valuable experience that put me in the position of service to the community.  I valued my legal internships with the Veterans Legal Assistant Clinic and top defense attorneys practicing in the region.

I have assisted professors in teaching contract and tort law.  I have experience serving clients in a variety of matters including: criminal, family, financial, and military matters.  

I strive to build strong relationships with clients and provide top quality legal service using the breadth of my legal and personal experience.
