If you weren’t an attorney, what would you be?
If I was not an attorney, I might still be an engineer, but more likely, I would be making furniture. I enjoy working with my hands and have always had a fascination with furniture making. I find a lot of satisfaction in creating things and furniture making takes a lot of skill, creativity and focus.
What are the top three attributes of your best clients?
Integrity, creativity, and vision.
What’s your favorite book?
Without a doubt, it is “The Pillars of the Earth” by Ken Follett. I have never read a book that is so engrossing and captivating (nor one that kept me up reading so many nights). The character development is absolutely phenomenal and the storylines, plots and subplots all flow together so well. It is a book that I have reread a number of times and have found it better each time.
