About me

My wife and I have three boys and are partners in our legal practice.  I am a former athlete including playing football in college and in fledgeling professional football leagues after college.  I have trained for and competed in an adventure triathalon.  I have competed in amatuer baseball including Men's Senior Baseball League World Series.  I stay connected to sports by coaching my boys in football, basketball, baseball and track.  I am competitive by nature and trained very hard to prepare myself to compete in athletics.  I bring the same work ethic and competitiveness to my law practice.  I work hard to gain the knowledge I need to excel in this profession and prepare myself to take on the competition.
