Personal Note

Growing up in a rural community in Ontario, Canada my greatest pleasures were exploring the woods and discovering and excavating indian villages. Naturally, I grew up wanting to be an archaeologist. I also enjoyed engaging in heated debates with my friends and acquaintances, many of whom told me that I would make a good lawyer. I followed their advice and have no regrets in so doing. My favorite pastimes are spending time with my family and friends, playing guitar, and collecting and restoring antiques. In my law practice, my greatest reward is receiving the appreciation of the clients with whom I work.
