About me

Attorney Blumberg was born and raised in Las Vegas, Nevada.  He only spoke Spanish until his parents entered him in pre-school.  Mr. Blumberg graduated from the Meadows School and attended the University of Miami for undergrad.


After graduating college in only three years he was accepted to the prestigious Emory University School of Law (currently ranked 22nd law school in the US).  Since 2004, Mr. Blumberg has devoted himself primarily to the constitutional liberties of others.  First as a Deputy Public Defender for San Diego County and later in private practice.  Never a police officer or prosecutor. 


Mr. Blumberg has extensive experience handling complex criminal matters in every Courthouse in San Diego County.  He has a stellar reputation and respect among local Judges and attorneys.  


Mr. Blumberg enjoys spending time with his wife and children, travelling and reading.
