Frank Gavidia, CFP®
Managing Partner & Chief Compliance Officer

Frank started 25 years ago in the industry as a Financial Consultant at Smith Barney.  While he enjoyed what he did, he always felt that there was more that he could do besides helping clients select investments.  Eventually he embarked on the study program to become a CFP® Professional.  In 2008, he earned the CFP® designation by completing the study program and passing the exam.  He began working with clients in a more comprehensive way but found he did not have all the tools he needed while still working at a brokerage firm.  This led to the decision establish Nissim & Gavidia Wealth Management & Financial Planning, LLC.  Frank firmly believes all Wealth Management begins with a plan.  Frank grew up in San Francisco and graduated from San Francisco State University with a B.S. in Economics.  He attended St. Ignatius College Preparatory also located in San Francisco.  Frank is also a veteran.  He served faithfully in the United States Marine Corp and was Honorably Discharged.  His military experience taught him to have discipline, and above all to always show integrity.  Frank is an avid soccer fan.  He currently volunteers at Mount Diablo Soccer Association as a youth coach, referee and Assistant Treasurer.
