About me

Beyond having better than 10 years experience in both sides of criminal law, I come with contemporary training in electronic surveillance law and recent constitutional issues.  I'm one of a handful of attorneys nationwide published in and experienced with BitCoin.  Other than that, I'm a dog person, casual runner, meditator, and amateur martial artist.
