David J. Ruyle, Jr. focuses his criminal and DUI defense practice in San Diego where he was born and raised. He received his Bachelor of Arts degree from Baylor University in 1998 and his law degree from Trinity Law School in 2002. During law school Mr. Ruyle interned with the San Diego County Public Defender’s office where he was exposed to felony related matters.

After working for a few years as an attorney on DUI and other criminal matters, he had a calling to better understand the public perception of law enforcement and the realities officers face. That calling led him to attend a California POST certified Police Academy in 2007 and become a Reserve Police Officer with the City of El Cajon. As a police officer, he was certified to use the PAS and Intoximeter to determine level of intoxication. He was exposed not only to the policies and procedures a police department and its officers must follow but effects they have on the community. During his commission as an officer he was exposed to drunk drivers, domestic violence, and narcotics offenders along with many other issues a patrol officer encounters on a daily basis. He enjoyed his participation in many community outreach events sponsored by the police department.

While he was a reserve police officer he continued his legal practice representing clients in criminal matters and was able to effectively apply his experience as a police officer to his cases and addressing his clients’ needs. He has since resigned his commission with the City of El Cajon but has a passion for sharing what he learned. He was able to share his real world and academic experience as an adjunct professor in the Criminal Justice Department of both Westwood College and the University of Phoenix. He now continues to work with students studying for the Bar Exam.

As a criminal defense attorney, Mr. Ruyle has represented clients charged with misdemeanors such as DUIs, domestic violence, drug possession and theft to felony cases such as severe domestic violence, burglary, robbery and narcotics. He takes pride in understanding his clients’ situations and being attentive to their needs while seeking a favorable outcome for their case. Also of importance to him is his clients’ ultimate well-being and the correction of any patterns of behavior that may be the underlying factor in their criminal case.

Mr. Ruyle is in good standing with the State Bar of California, a member of the San Diego County Bar Association and California Public Defender’s Association.
