  • Meet Me

    What do you enjoy most about your practice?

    I like being the "middle man" between inventors and the patent office. It's fun to be one of the first persons who sees new technologies being developed and brought to market.

    What are your favorite pastimes when you are not practicing law?

    I volunteer at a local food bank, run annually in a half marathon, enjoy reading newspapers from other countries, and camping in the US and exotic locales such as Iceland.
