Personal Note

When not practicing law, I am an active member of the California Aikido Federation and an instructor, holding the rank of Nidan for over 11 years. Aikido is a modern Japanese martial art, whose name can be translated to "the way of harmonious spirit". I am a strong believer that the same harmonious and peaceful conflict resolutions principles of Aikido can be applied to the legal industry.

I am a dedicated family-man, residing in Roseville, CA, with my wife, two daughters, chihuahua (Chloe) and 2 guinea pigs (Bob and Wilson).
