I have been with Lichtenstein, Briefman et al since 1987.  Prior to that I was with a local law firm for several  years.

Family time (just love those grandchildren), cooking, travel, and reading are my favorite outside activities.  Relaxing on the balcony of a cruise ship with a good book is a priority.

Never regret a day of your life, good days bring happiness, bad days bring experience and lessons learned but, the best days bring memories.  Always be true to yourself and you can never get lost.
