After law school, & a few years of working as a practicing attorney, Adam decided to pursue another degree, his 4th. He then studied at Golden Gate University, School of Law in San Francisco, California where he received an advanced Law Degree, a Master of Laws in Taxation, (LL.M. Taxation) while still working as a practicing attorney during his studies.
