Prior to law, I spent over a decade as a data engineer in both the Air Force and in the private sector. I’ve advised governments on securities laws issues, cryptocurrency issues, written and delivered CLE’s on securities law and cryptocurrency and delivered that training in Oregon and California. I’ve taken on state pension funds for imprudent investments, and helped create new law when Bitcoin was first thrust on the scene in federal court. I spent two and a half years on a pro bono 1983 case to help a convicted felon retain his right to a lifesaving medical treatment because I believe that community service is vital to an attorney’s life. I’ve never been known to back down from a good fight, and in my early years probably fought a little too hard on cases I shouldn’t have (but still obtained favorable settlements). 

My practice covers: securities law, intellectual property rights (trademark and trade secret infringement), cryptocurrency regulatory compliance, and various contractual disputes. I’ve handled qui tam issues, arbitrations, administrative law matters, state court and federal court issues, and acted as special master to judges regarding securities law and cryptocurrency matters.
