Board Members
SDCERS' Board of Administration is comprised of 13 Board Members. The fairly unique thing about SDCERS' Board is that the majority (7 of the 13 Board Members) are independent appointees - meaning they are members of the San Diego community who have specific qualifications and experience for Board membership, but they are not members of SDCERS. Since these seven members do not participate in the SDCERS pension system, they therefore do not have a personal stake regarding SDCERS benefits. The impartiality of the independent appointees, combined with the personal experiences of the Board Members who are also SDCERS Members, increases our Board's ability to be both effective and trustworthy in its administration of the SDCERS pension plans.

Paul Lotze
Active Fire Safety Board Member
Paul Lotze is a Fire Engineer with San Diego Fire-Rescue Dept. He is part of the Post Academy Training ("PAT"). As a PAT Engineer, Paul has the opportunity to drill, train, and mentor probationary firefighters. During his time at PAT, he noticed the need for new hires to have an understanding of retirement readiness, because, at the time, they no longer had guaranteed income through a pension or social security. In order to fill this void and help support his fellow firefighters, Paul co-created the first retirement presentation for new hires. His passion to serve in the area of retirement readiness overflowed to his entire fire family and this helped catalyze the first retirement account chart. Paul’s continued desire to serve the financial prosperity of all firefighters has led him to the position of Active Fire Safety Trustee on the SDCERS Board. Paul’s prior knowledge and application of financial awareness, as well as his willingness to serve, will now benefit his peers and their families for years to come.
