About Me

I understand the emotional difficulties of divorce, separation and paternity actions.  I know that each case presents unique facts and deserves my full attention.  My varied background includes having been a radio and television journalist and former business owner. I know my way around the court system and am an efficient litigator and advocate but do my best to settle cases whenever possible.
