Personal Note

I was drawn into the practice of law because I like solving problems and each case entails solving problems. In my career, the most important lesson I have learned is that I do not know everything and continue to learn.
If I were not an attorney, I would be a teacher. I love helping my clients and I have provided seminars for clients covering issues including basic workers’ compensation law, investigation of claims and case law updates.
