Thomas Wang

Attorney of Counsel San Diego 

Attorney Thomas Wang is what we call a “true believer” in the criminal defense industry.  As early as college, Mr. Wang came into contact with criminal defense litigation.

As a Junior attending the University of California - San Diego, Mr. Wang’s raw, yet sharp, legal acumen caught the attention of Laurence Benner, a criminal law professor at the California Western School of Law.  Professor Benner approached Mr. Wang with a challenge: to attend law school as an undergraduate.  Mr. Wang welcomed –and accepted- the challenge.

Over the next several months, Mr. Wang attended a law school class amongst admitted law students.  Despite clear disadvantages, Mr. Wang’s academic brilliance shined through.  Mr. Wang quickly distinguished himself with his legal mind, and ultimately graduated as the top student in that class.

Now armed with Professor Benner’s tutelage and his own success in law school, Mr. Wang decided to pursue a career as a criminal defense litigator.  Two year later, Mr. Wang returned to California Western as a scholar.

With his eyes set on a career in criminal defense litigation, Mr. Wang understood the importance of practical experience.  As such, Mr. Wang quickly became a group leader in Professor Benner’s San Diego Search Warrant Project.  Mr. Wang reviewed hundreds of search warrants, and determined if probable cause existed for such warrants.  Concurrent with his commitment to the Search Warrant Project, Mr. Wang also began to intern for the San Diego County Office of the Public Defender.  There, Mr. Wang served through various rotations over a three year span.  Mr. Wang served in Chula Vista, Downtown, and Juvenile Delinquency, and handled a variety of cases ranging from simple misdemeanors, felonies, to serious felonies.

In between his various stints with the Public Defender’s Office, Mr. Wang also externed for the criminal division of the Chula Vista Superior Court.  There, Mr. Wang authored bench memos to provide recommendations to judges on various criminal matters, including motions, writs, and appeals.

Despite balancing a tough work schedule, Mr. Wang’s academic success continued.  Mr. Wang would ultimately graduate with honors even though he never stopped working all through his law school career.  Along his way, Mr. Wang collected many accolades, including: 1) serving as an associate writer and editor of the California Western Law Review, 2) serving as an associate write and editor of the International Law Journal, 3) placing Second in the Gafford Trial Tournament, 4) recognized three times as a distinguished advocate, and 5) receiving the George S. Lee Scholarship and the Higgs, Fletcher, and Mack scholarship.

Given Mr. Wang’s demonstrated legal brilliance, it was no surprise that he passed the famously difficult California Bar Exam in his first attempt.  Thereafter, Mr. Wang began his career as a criminal defense attorney.  In the last year alone, Mr. Wang have handled a wide variety of cases, including: DUI, domestic violence, gang shootings, drug cultivation, child abuse, hit and run, welfare fraud, etc.

Mr. Wang’s many successes also translated to his life outside of work.  Currently, Mr. Wang serves as the Vice President of the San Diego Chinese Attorneys, and is a member of the California Attorneys for Criminal Justice and the Criminal Defense Bar Association.  Mr. Wang also taught various seminars on criminal defense at SDSU, UCSD, USD, and California Western School of Law.

Mr. Wang’s success is unparalleled.  And he credits his success to his appreciation for the “client-centric model” of criminal defense litigation.  In his own words, “criminal defense, unlike other areas of law, requires a tremendous amount of rapport and trust between the client and the attorney.  Nothing is more important to me than giving my clients the individual attention they deserve.”  Perhaps nothing demonstrates Mr. Wang’s dedication to his clients than the following testimonials:

“God's help through the hands of an attorney. Who would have guessed?”

“Mr. Wang listened to every word I had to say and then he started to anticipate my next question. Mr. Wang knew how terrified I am of courts, especially deputies or others in uniform. The penalty was very much in my favor due to Mr. Wang. I do and will recommend this gifted and talented man.”

“Wonderful Experience”

“I called Thomas the night before my family members arraignment. He answered immediately and answered all of my questions thoroughly and explained the entire procedure from arraignment to trial. My family thought my family member/defendant was without a doubt going to do jail time because of his prior criminal record. He was arrested for a felony and 2 misdemeanors. Thomas got him out of jail the next day with summary probation only! I'm so grateful we hired Thomas. He did everything you'd expect from a skilled lawyer and more! He even called me after his services to my family member ended to check on him and his progress and follow up on any unanswered questions. He was wonderful and did an amazing job for us! I have recommended him to everyone I know and will definitely hire him in any time of need!”

Mr. Wang’s demonstrated success and “client-centric” approach to criminal defense is a glove fit for us.  As such, we invited Mr. Wang to join us as an attorney of counsel.  We know that any client will be happy and fortunate to have Mr. Wang as his counsel.

Brandon Naidu

Attorney of Counsel San Diego

Brandon Naidu started his academic career as an Officer Candidate with the United States Marine Corps ROTC program at the University of Utah in 2004. While his goal was to serve his country as a naval aviator, a medical condition cut his military career short which forced him to re-evaluate how else he would serve his community. Mr. Naidu chose to take his bachelor’s degree to the next level by achieving his master’s degree in economics from the University of Utah, focusing on creative approaches to multinational economic crises.

Halfway through his master’s degree program, Mr. Naidu realized that the problems he set out to understand and solve could not be practically achieved through economic models and theories; but rather through direct action via the law. After earning his master’s degree, Mr. Naidu attended California Western School of Law, and early in his first year, he developed a strong interest in defending civil liberties and those accused of crimes. Mr. Naidu accepted a position with the California Western Community Law Project, where he primarily worked and assisted San Diego citizens accused of crimes without adequate access to representation. As a recipient of California Western’s Academic Excellence Award, and, law clerk with various law firms as well as, the Legal Aid Society, Mr. Naidu continued to drive his passion in criminal law.

Mr. Naidu trained with the best DUI defense attorneys in Southern California. As a practicing attorney, he has continued his focus to providing a high standard of criminal defense for his clients. Mr. Naidu has dedicated his career to the defense of individuals accused of driving under the influence and other criminal offenses.
