Clark Ovruchesky was born and raised in San Diego, California after his family emigrated from Russia. Clark graduated from the University of California, San Diego (UCSD) with a B.A. in Political Science. He then worked for a family law firm, which confirmed his desire to become an attorney.

Clark ultimately decided to attend California Western School of Law and was awarded a Faculty Scholarship, which he maintained all three years. During law school, he became a Student Bar Association representative for his class and served on the Moot Court Honors Board.

Clark worked for several local civil law firms during law school, and as a judicial extern for the Honorable Peter C. Lewis, United States Magistrate Judge, U.S. District Court, for the Southern District of California, in El Centro, California.
